Graphics = Nvidia GeForce 6600
OS = XP SP3
RAM = 1024MB
CPU = Celeron 2GHz
yes my computer is old (about 6 years)
when i first got my computer everything was fine, it did not have a graphics card and it had 256MB memory. i eventually put in 1024GB of memory and a graphics card. sometime down the road, my computer started to freeze on screen saver (not all the time though). this eventually escalated into a restart. i have re-installed the OS about 4 times. recently i re-installed the OS to clean things up a bit, i only have a 30gb hard-drive. i tried to put little games on it, like warcraft, half-life, doom, etc. all of these games ran fine before i re-installed my OS (they even ran without my graphics card). i tried to play some games and about a min into it (even before playing) my computer re-starts itself. it happens on all the games i tried. i tried to re-install the OS again, and the same problem. i did a mem-test, both when my computer was on and on start-up, and they both came back fine. i did a disk check, everything was fine. i tried without the graphics card, same thing. i tried different ram, same thing. my computer feels like it is running cold, but to be sure i have mbm5 and it says that my computer is around 100°F. but sensor 3 is running at 168°F, the only problem is, i don't know what that sensor is for. i checked the BIOS temp readings all three readings were around 100°F. i even tried with the case open (the case has a fan on the side).
what do you suggest?
i think that my mother-board is just crapping out on me, its been 6 years.
