Nothing can put a damper on productivity quite like a computer that crashes on a regular basis. Sometimes, a crash is preceded by the dreaded “blue screen of death” or another warning; other times, a computer simply shuts off without any warning at all. In either case, the end result is a whole lot of frustration, aggravation and lost work. If your computer has been crashing frequently, you’d probably like to put an end to it. Unfortunately, getting to the bottom of things if often easier said than done. The following tips about improving your computer’s performance, though, are excellent places to begin.

Possibility #1: Corrupted System Registry Files

Every Windows-based PC has something called a Windows registry. The registry contains several files that are integral to the performance and operation of your computer. Over time, some of those files can become corrupted, be misplaced or get lost altogether. When that happens, the system registry becomes compromised – and frequent crashes are all-too-common symptoms. The best way to rule this possibility in or out is by running a Windows registry cleaning program. Such programs scan your Windows registry for problems then automatically make repairs. If you run a registry cleaner and the crashes persist, they are probably being caused by a different issue.

Possibility #2: Disorganized Files

Windows operating systems handle file organization in a way that isn’t very intuitive. Basically, they break files up and fit them into gaps in the computer’s memory. As time goes by, these disorganized files can prompt frequent crashes. Luckily, a great optimization solution is built right into Windows-based PCs: the disk defragmentation utility. Although its location on a computer varies, you can generally locate it within the System and Security section inside the Control Panel. By running a defrag once every few months, you may be able to keep those pesky computer crashes at bay.

Possibility #3: Malicious Software

Malicious software can take many different forms. Sometimes, it’s a virus that is accidentally unleashed after opening a strange email; other times, its adware that tags along with other information that is automatically downloaded from a website. Whatever type it is, there’s no question that malicious software can wreak havoc on a computer’s performance. Happily, there are many topnotch programs out there that regularly scan your computer for the presence of such problems – and that help guard against them, too. Buy one, install it and use it regularly; your crash issues may come to an end.

Possibility #4: Too Little Available Memory

When you buy a new computer, it feels like there’s no end to the amount of memory that it has. Of course, this isn’t true at all. As never-ending as the available memory on your PC may initially seem, the fact is that it can be depleted with incredible speed. You can find out for sure by checking the information within “My Computer.” If it appears that your available memory is low, you can use a PC cleanup program to remove unnecessary files; such programs remove things like temporary Internet files and other file debris that can suck away much-needed memory.

Possibility #5: Overheating

If you’ve run through all of the preceding possibilities and continue experiencing frequent crashes, a hardware issue could be to blame. An easy one to rule out is overheating. A computer’s CPU, or central processing unit, includes a fan that is designed to keep it running cool. Sometimes, the fan wears down and doesn’t work as efficiently; other times, it’s just not able to handle the work that your computer has to do. In either case, buying a bigger, better fan isn’t very expensive. If it puts an end to your PC crashing problem, it will have been more than worth it.

Don’t Put Up with Frequent Crashes!

As discussed, frequent computer crashes can be triggered by a wide variety of issues. Luckily, many of these issues are relatively easy to remedy. Work your way through the preceding list; chances are, you’ll be able to pinpoint the problem and put an effective cure to work. Nine times out of ten, a computer simply needs a little bit of routine maintenance to get it back on track again. In the future, keep these points in mind. Any time you buy a new computer, keep up with its basic maintenance right from the get-go. By doing that, you could avoid “blue screen of death” and crashing problems altogether – and that’s something that you’re bound to appreciate!

Tips for Speeding Up Your PC

Few things are as frustrating as dealing with a slow, sluggish computer. When a computer is brand new, it works wonderfully well. Over time, though, its performance can slowly begin to worsen. This happens for a number of reasons, but the biggest culprits are things like spyware, adware and other computer threats that are unwittingly downloaded along with other content while online. You don’t have to download thousands of MP3s, movies or other items to experience these problems, either – nobody is immune to them. Instead of accepting the situation, there are plenty of techniques and strategies that you can use to make it better – a few of the best ones are outlined below.

Strategy #1: Clean Your Computer’s Windows Registry

The biggest cause of slow, sluggish PC performance is errors and problems within its Windows registry. Adware, spyware and other threats usually target the registry, damaging or misplacing important files within it. When it comes to PC cleaning, a daily Windows registry cleaning should be at the top of your list of priorities. However, this should never be done manually – there are too many opportunities for major errors that could seriously damage your PC’s operating system. Instead, invest in a high-quality Windows registry cleanup program and configure it to run once per day – you won’t believe the difference that it makes.

Strategy #2: Remove Unneeded Files

Every time you log on to the Internet or otherwise use your computer, temporary files are generated. They are usually only needed once; however, they don’t disappear on their own. Instead, they accumulate over time until they are cluttering up your computer’s file system and affecting its performance. While it’s possible to remove these files one-by-one, it’s much easier and quicker to use a PC cleaning tool that’s designed for the purpose. Try to do so about one time per week to keep your computer humming along with ease.

Strategy #3: Remove Unneeded Programs

Like many people, you probably download and try out many different programs each month. How many of them do you actually end up using on a regular basis? Chances are, not very many of them. By getting into the habit of uninstalling unused and unneeded programs, you can keep your computer’s file system a lot less cluttered. In turn, your PC’s performance will improve dramatically. You can optimize your computer in this way by using its Add/Remove Programs feature. Its location varies by operating system, but you should be able to find it somewhere in the Control Panel.

Strategy #4: Empty the Recycle Bin

When you click “delete” on a file or a program, it doesn’t go away for good – not immediately, anyway. Instead, it sits in a kind of purgatory in your computer’s Recycle Bin. As things pile up in the Recycle Bin, your computer can start exhibiting some very annoying problems. If sluggish startups and frequent crashes are occurring with increasing frequency – and your computer’s recycle bin is very full – go ahead and empty it. From then on, get into the habit of doing so about one time per week. This small but important strategy can make a huge difference.

Strategy #5: Perform a Disk Defragmentation

Windows isn’t very efficient when it comes to storing files. It actually splits them up, depositing them into whatever spaces are available. The more spaced apart the pieces of a file are, the harder your computer has to work to make them run. The Windows disk defragmentation system tune-up utility works to piece all of those files back together again. The process is a long one, though, and only needs to be done about four times per year. Set it up to run automatically once every three months. By doing so, you’ll be able to keep your computer running in tiptop shape.

When it comes to keeping your computer running optimally, small but regular maintenance is the best way to go. Protecting your PC only does so much; even the most careful Internet users in the world unintentionally download malicious software from time to time. By using basic system tune-up tools, cleaning your computer’s Windows registry regularly, performing regular file-cleaning maintenance and otherwise optimizing your PC, you should be able to keep it in like-new condition for a lot longer. Even if your computer has been performing slowly for some time, beginning this regimen is sure to produce results. In the end, you’ll be able to enjoy a computer that flies along – instead of one that spins its wheels.

1. Change channel number

Wireless routers operate on a fixed channel. Since most routers ship with a pre-selected channel, the wireless signal may interfere with other routers in the vicinity that are operating on the same channel.

Changing the wireless channel from the factory default is a good starting point if your wireless signal strength is poor.

2. Give the router space to breathe

The biggest advantage of a wireless router is that it can penetrate doors and walls – but that doesn't mean you can just stuff it next to a wall or cordless telephone, or use it as a stand for your stack of DVDs. Treat it with respect.

Try to keep it in a central location, away from other wireless devices; make sure it's not in direct sunlight; lift it off the carpet; and ensure its vents and air holes aren't covered.

3. Improve reception

Try as you might, you'll find it's sometimes not possible to put the router in a good spot. One way around the problem is to buy a router with multiple antennas and point them in a variety of directions covering your home.

Alternatively, if you've already got a router, check whether it's possible to upgrade its antennas to something stronger. However, don't get disheartened if your router doesn't have any antennas. A wireless repeater compatible with your router is a perfect solution.

4. Use WEP

Running an unsecured network will earn you brownie points from neighbours and hackers with cars, but that's about it. Wireless routers support a variety of encryption methods, such as WPA and WEP, but these aren't enabled by default.

WPA2 is the most secure method at the moment, but before deciding on an encryption method, make sure your network cards and adapters support it as well. Bear in mind that older machines – and games consoles such as the Nintendo DS – don't support WPA.

5. Restrict access to specific PCs

If you really don't want to use encryption, you can force your router to only connect to specific PCs. Your router identifies each computer by the unique MAC address of its network gear. Feed it a list of MAC addresses to connect to and you save yourself the trouble of entering a password each time you log in.

The disadvantage is that you'll have to add the MAC address of any new computer before it can get on your network – which is probably a more annoying way of getting things done.

6. Disable SSID broadcast

All wireless routers have a Service Set Identifier (SSID) that identifies them to network computers. Routers from the same manufacturer generally ship with the same SSID; 'Netgear' or 'Cisco', for example.

You should first change the SSID to something unique to set your router apart from those of your neighbours. Then, once all your hardware has been set up, it's better to turn off broadcasting the SSID altogether. This ensures your router isn't displayed in the list of available networks, and won't be a target for potential hackers.

7. Keep the firmware updated

Router manufacturers keep working on firmware, even after hardware has been shipped. In addition to tweaks in the user interface, new versions might make better use of the various components in the router, or add extra features.

Just like with an operating system, it's a good idea to upgrade the firmware of the router regularly – check the manufacturer's website for a new version. In the good old days, there was the risk of a botched firmware upgrade bricking your router, but it's a lot safer today.

8. Familiarise yourself with the router manager

All routers ship with a browser based manager. To use many of the tips in this article, you'll have to log in to this interface – try typing 192.168.1.1 into your web browser for the most common location.

It's a good idea to familiarise yourself with the various options and settings you can tweak from within this software. Many routers also have detailed documentation that's updated regularly, so hunt out the latest manual online.

9. Check your connections

There's nothing more irritating than receiving a 'cannot connect to remote machine' error. To ensure a solid connection, use Ethernet cables where possible. It's also a good idea to check the connection between the two PCs with the ping command.

To do this, simply open a command line and type, for instance, ping 192.168.1.2. You'll need to replace the address given here with that of your target machine. Ping works identically on Windows, Mac and Linux.

10. Forward ports

Many servers and applications – for example, file-sharing software, FTP servers and music-streaming servers – need to serve people outside the network. These applications accept connections on specific ports.

With port forwarding – check your router's interface – you can poke holes in your router and ask it to direct incoming traffic on a particular port (or, if you wish, a range of ports) to a specific computer that's on the network.

11. Change DNS providers

DNS is what fetches you a website by translating the human-friendly address, such as www.pcplus.co.uk, into a bunch of machine-friendly numbers. It also displays the '404 page not found' error, corrects misspelt URLs and finds the fastest route to a web server that hosts the site you want to visit, along with lots of other cool things.

Generally, it's up to the ISP to put up a DNS server. However, there are other free services as well, including the likes of OpenDNS and Google Public DNS.

12. Use USB adapters

These days, it's difficult to find a laptop or netbook without a built-in wireless module, but if you've used one, you'll know that they can't always be relied upon. Network cards with antennas are the best option, but they're really only suitable for desktops.

If you really need both mobility and assurance, make sure you get a USB adapter. Most of them ship with a Windows driver, but many work out-of-the-box on Linux as well.

13. Enable Dynamic DNS

The Dynamic DNS feature enables you to connect to your computer remotely. Back in the day, when real-estate on the web was expensive, it was a wonderful option to show off your HTML skills and host your own website.

Now, by associating your dynamic IP address with a domain name, DDNS enables you to connect to the internet-exposed home computer from anywhere in the world. In addition to enabling the feature on your router, you'll also have to register with a dynamic DNS provider, such asDynDNS.org.

14. Save power with Wake-on-LAN

What's the point of keeping a print server on when there's nothing to print? The smart way to save energy is to use the Wake-on- LAN feature of the network card. Thanks to this, you can put the machine to sleep after it's been configured to wake upon detecting network activity.

15. Encrypt your online activity

With the range of snooping tools now available, it isn't safe to do anything online without covering your footprints. There are lots of tools that promise to encrypt your online activity, making it completely unintelligible to anyone who might be listening in.

Some of the best ones to try are the Enigmail plug-in for Thunderbird,Psi for Google Talk and FireGPG, available for Gmail.

16. Get a Firewall distro

You can configure a firewall on a Windows or Linux machine, and there are also a bunch of third-party software firewalls available. However, building a firewall isn't easy. If you're serious about putting one up, download a dedicated firewall distro, such as Ebox.

17. Install the software

Ebox is distributed as a Live CD ISO and there are VirtualBox/VMWare images as well. It's based on Ubuntu Server 8.04. You can also pull in Ebox packages to a standard Ubuntu Server 10.04 installation. You can find it atwww.ebox-platform.com.

18. Configure settings

Ebox can be adapted flexibly to your network. You can use it to restrict services that can be accessed and slice the network to keep some areas more secure than others. The distro runs a browser-based interface for adding, removing and configuring the components.

19. Filter content

Besides the firewall, intrusion detection (via Snort) and filtering content (via DansGuardian) are two other highlights of the distro. DansGuardian can also plug into the ClamAV antivirus scanner and filter content based on known virus signatures.

20. Exploit other features

In case you're still not satisfied, Ebox can also act as a gateway and provide a host of other services. It bundles various applications that enable you to turn your network into a VPN, host XMPP chat sessions or run a Postfix mail server, a Squid web proxy and more.

21. Turn on UPnP

Universal Plug and Play helps smart devices that support UPnP to discover each other without any user intervention. Once turned on from within your router, UPnP enables a compatible infrared device, a Bluetooth phone or a FireWire camera to see and talk to each other.

22. Write files remotely

The most logical use of a network is to share files. This is the job of the SMB protocol. Thanks to it, you'll be able to write files to a remote network share via Network Neighbourhood. On Linux, the SMB protocol is implemented by Samba.

23. Share printers remotely

In addition to sharing files, SMB can be used to share printers attached to a Windows machine. Once configured via the Windows Control Panel, a printer can be used to accept print orders or even be managed from a remote machine, irrespective of its operating system.

24. Format shareable partitions as FAT

PCs running Windows can easily see each other and share files. For Linux or Mac machines, ensure the partitions are formatted with the FAT filesystem. Create them as Samba shares and they'll show up under Network Neighbourhood.

25. Plug in USB drives

Once, if you wanted to share files on the network, a network-attached-storage, or NAS, device was the best bet. Not any more. New routers enable you to plug in one or more USB devices that are automatically accessible by all the users connected to the router.
