Ive also ran Windows Memory Diagnostics at 6 passes, No errors found
Also ran MEMTEST86 - for 8 hours, no errors found
Post 5 for the above.
Post 11 is Speedfan screenshot which clearly shows the temps and voltages are well within acceptable ranges.
I do agree the make and model of the PSU was overlooked by myself and thank you for pointing that out.
Also the make and model of the GPU will help in determining if the PSU is indeed enough to run it.
Ahh, I missed that line.
And I agree. That power supply should easily be enough for what you've got.
However, I don't know how much I trust Speedfan Due to issues in the way in interfaces with the motherboard using its own, weird/poorly written driver, I've seen Speedfan report really strange things that don't mean anything, but can be misinterpreted as hardware problems to the inexperienced.
Also, it doesn't really matter if Speedfan is showing acceptable voltages during the system idle. What really matters is the one voltage dip you get when you begin to load the system. As all the transistors in the CPU begin to turn on and off, that voltage demand draws a significant load from the PSU, which must quickly compensate or all is lost. In fact, with most digital (i.e. Software) voltage recorders, it is impossible to detect this drop it is so short and sudden (in my experience). You really need a voltmeter with a really fast sampling rate on the PSU wires directly. Because of the danger of monkeying with the PSU, this is NOT RECOMMENDED. Since we are able to confirm successful operation of the other key components in the system (mobo/memory with MEMTEST, hard drive with CHKDSK), it only makes sense to focus on the PSU. Since we are able to stress the video card, I would say this points specifically to the CPU 4+4 circuitry as the failure/weak point. Unless you have a PSU tester that can power up the PSU and apply an artificial load, the only way to verify this is with a new/known good PSU.
I did forget to mention that i discovered my HDD SATA cable was loose, and not sitting in place very well. I just went to CompUSA and purchased a new one, which i will install tomorrow, perhaps that may resolve an issue here or there.
Interesting. This could be the cause of the problems that we're seeing. However, I'll be skeptical because you have never reported errors booting. If you hard drive wasn't properly transmitting data to the system (which is what a loose cable implies), then I don't see how it would let you successfully boot up time and time again, but only fail under user-induced load.
