Dying computer

Hello Dual boxing community,
Lately my computer just dies i have no idea why though. I've tried everything to get my games to work. (WoW, Red faction, L4D, etc) I've reinstalled i have checked ram, video card, i have even completely reformatted my computer! please help!!!:(

Here are my computer specs
AMD Athlon 63 X2 Dual Core Processor 6000+
2.00GB ram
Nvidia GeForce 8600 GTS

2GB ram is not enough to multibox on. Maybe your hard drive is getting overloaded with page caching.

if your computer is dying, do you mean it shuts off for no reason?

could be a overheating problem, if so you should look at improving the cooling/airflow in the machine.

Need to clarify what you mean by "dying". Sutting down? Freezing up? Completely? Can you get the task manager to come back up? What OS?
