Useful Links

Driverguide - huge driver database search engine. Very useful if you have lost the drivers for a particular hardware item and you cannot locate the manufacturer's web site (if any).

Windrivers - Pretty much the same as above. Try here if you cannot locate the driver you require on driver guide.

Hardware review sites

Tom's Hardware guide - The best hardware resource site. If you are looking at buying new computer parts such as a new motherboard or a new graphics card, check this site to see which one is the best value for money. There is a lot of cheap and nasty computer components around and this site sorts out the best from the rest to avoid potential PC problems with cheapo components. Also has a load of information on how to overclock your CPU for those who want to squeeze as much performance as possible from their current system without upgrading.

Hardcoreware - This site is a good resource for hardcore gamers who demand the best and fastest computer hardware. Not as much info as the site above but definitely worth a look.

Computer monitor related stuff

Computer monitor schematics

This is a Russian site but however the manuals / schematics are in English. Just click on the monitor make and model and this will link to a downloadable file. Very useful.
