After building and maintaining PC's for as long as I have, there is still one VERY common problem that I continue to overlook. The power supply. Not only do most people forget to consider that when adding new drives, ram or updating their processor, but they can also slowly go bad and provide flaky power to your machine. This often leads to unpredictable and unexplainable errors, crashes and lockups. Post what type and wattage of power supply you have, and how many drives (hard drives, cd/dvd), memory, etc in your machine. Do you have lots of USB peripherals, etc? Anything that uses power (at least a significant amount...don't tell me you have a keyboard :). Then either take a spare one that you or a buddy owns that you KNOW will be powerful enough and is working properly. You aren't really a nerd unless you have at least one spare. Maybe it's in another machine. Turn it off and tear out it's power supply. Run your machine for a while (the longer the better) with the "new" power supply in there and see if that helps. If so, go buy yourself a power supply and rejoice at your newly functional machine. If not...well...we've all seen "Office Space".
