Something very weird is happening at the moment. Upgraded to an AMD 6400+ 2x CPU about 2 months ago. Had a 600W powersupply... [need it for the GTX8800 3D card] and since about 2 weeks ago, PC has been shutting down completely - asif u pulled the AC power! Just DEAD!
Eventually replaced the power supply with a Gigabyte 550W, and it still does the same. These power losses are randomly - not able to reproduce it --- and it's not overheating - CPU is running at about 54 degrees and my mobo at 48 degrees.
Any ideas?! And yes, I know it might be the motherboard, but I can't fork out about R1500 for a new mobo, only to find out it might be something else.....
T :S
