When your pc goes wrong it is usually time to pay someone to fix it, or call in a big favour from your favourite computer geek of a friend. Sometimes though it's not always necessary to fall back on these two alternatives to repair your pc. There are an abundance of tools supplied with Windows, or for free download which you may be able to use to fix your own pc. The first thing to realise before you start looking into fixing your own pc, is that most of the time it's a software fault, and not very often hardware related, so don't break out the hammer and chisel to open up the case just yet. It's time to stop, and consider when the fault first manifested itself. Had you just installed some new software or updates to your existing software? Have you downloaded a new Internet Explorer plugin or did anything request permission to install itself while you were surfing? Have you updated a device driver or installed some new hardware?

If the answer to these questions is "Why Yes, what harm could that possibly do?" then it could be that the culprit is a conflict with the new program or update. If so, then you could try using the software's uninstall link, or the "Add/Remove Programs" section in the Control Panel (Control Panel is linked from your start menu usually). If this doesn't work, you can always bring out the big gun, and use the "System Restore" utility. This can be found in the Start > Accessories > System Tools folder. This can be extremely scary the first time you use it with all kinds of warnings and texts to read, but basically it will roll back your computer to one of the previous dates it has stored. It doesn't delete documents or emails, just removes any software installed after the date you're going to reset to.
