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.

Hello 5ft24,
My train of thought would have been, Heat-Psu-HDD, you seem to have covered all that, so have you cleaned the system ?.
It's all thats left really. Run Malwarebytes first,and then CCleaner. (backup registry when prompted).

Take a look at these two tutorials, I would run them both.
Good luck and post your results.


Malwarebytes.org

CCleaner - Download

Startup Repair

System Files - SFC Command

Hello 5ft24,

Sounds like a hardware issue to me. Since you changed the PS, have you looked at the MB? Some MB keep an “Event Log” which keeps a record of hard faults such as MB or CPU faults. The log is usually accessed through the BIOS. If yours does, have you checked it lately? It could/should give an indication of the problem.

Yep, no errors on the MB. I had also swapped SATA ports on the MB so the 500GB drive was on the primary SATA port (Same as the 1TB drive)
If the repair or a clean install doesn't fix it, then I will have to suspect the 1TB drive.

Have you tried flashing the motherboard?

Yep, Reflashed with the latest Bios (Which is what was already in it)
Set all params to the "safe" defaults and then back to my settings... Definitely appears to be the 1TB drive, as it works just fine with the 500GB drive on the same SATA port.

Try running check disk on the drive and selecting both boxes including fixing file system errors automatically. You might to defrag your pc first.
