serious hardware failure... what's the cause?
I've been having bluescreens for about a year, I had assumed it was a faulty graphics card, so I recently bought a new BFG gForce 6800 GT, but I have still been getting the errors while playing Warcraft. I downloaded prime 95 and it confirmed a hardware error. I downloaded motherboard monitior, and it says my cpu diode temps are 150-160 degrees and my +12 voltage is usualy dropping to like 11.9. I ran some 'power supply calculator' which said i needed a minimum 285W power supply, but my power supply says its 450W? How much of the 285 is the +3 or +5 V which mine says has a 220W maximum? I really have no idea how to confirm what is wrong with my computer so I can fix the right thing the first time.... any help would be greatly appriciated
