Computer "hisses" and shuts down!

Hello, everyone.
Recently, my computer has started to act up. When I turn it on, it emmits a sort of electronic hissing noise whenever it thinks. The noise isn't loud, but present none-the-less. It takes about 15 tries for the computer to actually fully boot, restarting in between each try on its own. Finally, when it is all set, I'll be working on something, and it will randomly restart again, without any warning at all. Any help would be appreciated! Thanks!

It sounds like a critical hardware fault. Back up your important data and files as soon as possible!

Often the symptoms you describe are indications that your hard disk drive is about to fail. This means it will permanently be damaged and will need replacing. All of the data on it will be lost once it has had what is called a "head crash".

If you are computer savvy, once you have backed up your files, you will need to purchase a new hard disk, swap it for the existing one and then reinstall Windows (your operating system). There is an illustrated guide to replacing a hard drive as well as the official Microsoft guide for reinstalling on your new drive: How to install or upgrade to Windows XP.

You will need a screwdriver, your Windows XP CD, some time and patience. If you don't want to do it yourself, find a trusted local computer store that will do the job for you. It shouldn't cost any more than £50 in fees.
