Well, the test finished significantly faster than I had anticipated.
The results came back with no errors.
Perhaps Memtest86 from:
http://www.memtest86.com/ is not compatible with duel core processors, or at least not my specific processor.
Here is a quote from the homepage:
Listed below are a few of the planned projects.
* Support for memory testing using multiple CPUs. Code is needed to detect, select, park and start CPUs. In addition new methods need to be created for effective memory testing using multiple CPUs.
Anyway, the test from:
http://www.memtest.org/ was able to ascertain more information about the processor and memory, and came back with zero errors.
I was sort of hopping the problem was Hardware related so that I could just replace a part, and have the system work properly, but now I think I am back to the drawing board.
Perhaps the power supply is not large enough? Is 630W sufficient?
The computer was freezing at random times, with no discoverable cause. Sometimes the computer would boot up with no video output, but seam to go through the rest of start up just fine.(with no output detected by the monitor). Also, arbitrarily the computer would return from sleep with no video output, which could sometimes be fixed by a forced shutdown and restart, and other times not.
Could it be the graphics card? When the computer is working, it will run games like Crysis 2 and Spore just fine, so I was banking on a memory issue.
I suppose the next course of action would be to reinstall the operating system, and see if that fixes the problem. I wish I could replicate the problem, or get some error code to look up.
