Computer Specs:
CPU: Intel Core 2 6600 @ 2.4ghz
Graphics Card: BFB NVIDIA 8800GTS
Motherboard: ASUS P5B
Memory: 2GB Patriot PC2 6400 RAM
Power Supply: Aero Cool 650W
Hard Drive: 320GB Seagate
Thermaltake Cooling System
Operating System: Windows 7 Ultimate


Here is my problem:

The computer is very fast(could be better with better RAM), has 5 or 6 fans buzzing around in there and the graphics card is great. It runs most every game out there and can handle Adobe CS4 without even missing a step. However, when I am off of the computer for a few hours, and itís on, it will just randomly shut off.

My first thought was that it was too hot, but I check the temperature inside the tower in system setup and itís mid-40ís and I honestly have an amazing cooling system. So I doubt it shuts off because it gets too hot. Then I went and looked at the tower and on the mother board there is a bright green light that is on!? So I have to flip the switch on the power supply and then 3-5 seconds later the light on the mother board shuts off. Then I turn the power supply back on and then turn the computer on and it fires right back up again, no problems at all?!

I just donít know what this could be?? What would cause the computer to shut off, but the motherboard is still on until I turn the power supply off? Is it the graphics card? Does RAM have anything to do with it? I am so clueless and canít afford to go pay a repair shop $70/hr to diagnose it! Any help will be greatly appreciated!!! Thank you.

Could be infected with a virus.

I just reformatted on Monday, so there really is nothing on the hard drive! So I don't think it's that.. And what is weird, is when I turn it back on, it will run for a few days just fine and then out of nowhere it just shuts off, but the MOBO stays on! so weird?!

They are on balanced. Do you think it could be Windows 7 shutting the computer off if I don't use it for 30 minutes? Or do you think it is a hardware problem? I feel like the parts are new enough, and it works fine when it's on.. I wish there was a master chip that could tell you EXACTLY what was wrong without testing each component individually
