Hi there -
I've had intermittent hard shutdown problems (computer turns completely off, no reboot) for over a year and with money available have begun to narrow it down by switching in new parts, etc.
I've switched from a normal HDD to a SSD, Memtest'd the you-know-what out of my RAM, and experienced the shutdown with both onboard video and my current GPU (using both VGA and HDMI ports on each). I also just reinstalled Windows 7 for the sake of cleanliness, twice. All of my temperatures are fine, all of the time.
The only parts I have not changed at this point are the CPU and Motherboard. I just don't think it'd be a CPU issue for a full year running which leaves me with mobo and PSU. For as long as I've had this issue, I cannot remember if I switched my PSU for the sake of thinking I needed a "better" one or if this was done in response to the problem. Luckily I do have two for testing.
For the sake of not knowing, each PSU is labeled as potentially bad or potentially good. I just don't know yet ha.
My voltage values from the PSUs with HWMonitor and BIOS readings:
Potentially good unit (500W) cannot replicate shutdown with this unit:
HWMonitor - (12v)[11.88-12.03], (5v)[5.08-5.10], (3.3v)[3.33-3.34], (GPU's VIN0)[1.10]
BIOS - (12v)[12.03 constant], (5v)[5.082 constant], (3.3v)[3.327-3.342]
Potentially bad unit (650W) was installed for every known crash:
HWMonitor - (12v)[12.08], (5v)[5.04], (3.3v)[3.34-3.36], (GPU's VIN0)[0.90-1.10]
BIOS - (12v)[12.08], (5v)[5.042 constant], (3.3v)[3.342 constant]
So the biggest discrepancy between the two is the potentially bad unit hovers somewhat higher on the 12volt and varies back and forth between the GPU's VIN0 voltage from 0.90 to 1.10 while the good unit is locked on its GPU voltage. It is a PCIe card so it draws all the power from the board.
That being said, here are my current specs:
AMD Phenom II X6 2.8GHz
GSkill 2x2GB 1333 DDR3 kit
AMD HD6670 1GB
Crucial M4 64GB SSD
Any help would be greatly appreciated.
Thanks!
