My computer has been running very stable since a cpu upgrade four months ago. Tonight I fired up Bioshock 2 and a few minutes in, the computer just shut off like someone flipped a light switch - no warning.
The 400w power supply was too hot to touch and I got a small static shock when I touched the case. Doesn't seem good. I let it cool down and then tried to boot - nothing - it behaves like the power is completely off. I disconnected the motherboard and components and then tested the 20+ pin ATX power plug using a voltage probe - it has power - at least enough to run a small light bulb.
What doesn't have power is the 4 pin 12v power plug that connects to the MB near the cpu.
Is this normal that I wouldn't be able to see a current in the 4 pin power plug using a voltage probe grounded to the case?
Is there any sort of test I could use to rule-out the power supply besides try it with a new MB?
Components:
Rosewill 400 W (max) power supply
MSI K9A2 CF V2 (125 W max CPU support)
AMD Phenom II 955 X4 3.2 GHz processor (125 W)
Asus EN9600GSO Nvidia 9600 GSO GPU w 384mb DDR3
4 GB OCZ DDR2 PC2-6400 RAM
Western Digital Caviar Black 640GB
Western Digital Caviar Blue 500GB
