My Vista x64 PC is randomly powering off. MSI Neo4 Diamond MB, AMD athlon 64 X2 4200+ CPU, 2G ddr2-800 ram, 1TB and 500GB SATA drives, ATI Radeon HD4350 video card.
started a couple months ago. either you get into Vista and are working and suddenly pow... it goes off like pulling the power cord. sometimes it will do it right before the screen gives you the login to Vista...
Thought it was a power issue and upgraded a 500W supply to a 750W modular unit. No change... have completely disassembled the unit, cleaned everything, cleaned the CPU/heatsink and put new Arctic silver in. I can sit in bios all day watching the hardware monitor and the CPU never get's over about 30-31 Degrees C. Voltages are good and steady.
as soon as it's booted to Vista, it starts... even sitting idle it will do it. I have Windows XP and Windows 7 RC on the 500G drive. if I boot to either of those OS's, it will run for days without ANY issues... it is ONLY vista that has the issue. I thought it may have been the drive, so I made an image and restored it to the 500GB drive, then removed the 1TB drive from the system... Same issues.
