So my computer is custom built with an AMD Athalon XP 2400+ processor, a 120 GB western digital hard drive, an NVIDIA GeForce 6200 graphics card,and a jetway v400abdl motherboard with updates bios. Now my computer just randomly reboots itself. sometimes this is while playing a game, surfing the internet, or just doing nothing on the desktop. When it reboots it comes up with a stop error that says there is probably something wrong with a device driver, but all my drivers are up to date as far as i know. also i have reformatted my hard drive and reinstalled windows xp home with no change in the problem....Besides the random reboots, there is also a problem when running certain programs, such as internet explorer, windows media player, firefox, autodesk inventor, and many PC games. Basically the programs freeze up constantly and ask to send error reports, and then i must reboot the program. This is a problem especially when im working on a report and programs constantly freeze after being in them for maybe only 20 seconds. ive been at this problem for a while with no one haveing been any help to me yet....ive tried testing my ram, changing my video card, updating everything, and testing the the system temperatures....i just dunno what to do anymore, can anyone help?
