My latest build, a Phenom 9750-based system, has been troublesome since September.
In September I discovered (the hard way) that the memory seemed to be bad.
Long story short, after replacing both the memory and the motherboard, the sucker is still acting up.
Replacing the memory at first seemed to make the problem go away, til around mid November (2 months to the day). I decided then that there must be something else at work here, and swapped memory with a friend since I had no other DDR2-capable systems. 24+ hours of memtest86 showed no errors on either system. At that point I replaced my mobo. A few days later, it's crashing, rebooting, and in general misbehaving. Memtest86 actually crashes. (it did before on the old mobo too)
The cmos doesn't have a voltage monitor, so I don't know what voltage the memory was running at. I manually set it to 2.2, the voltage indicated on the sticker. Still there are problems (but only after ~36 hours). I ran SpeedFan and enabled logging on it. No heat anomalies preceding a crash.
Previous motherboard was an ECS A770M-A. New one's an Asus (don't recall the model, will check when I get home).
Memory is Crucial Ballistix DDR2-1066, cas 5-5-5-15.
My thoughts on it: Could the memory have actually been damaged if it were running under-voltage for long periods? That might explain the disappearance of problems upon replacing it, only to have them reappear later. It only ran on the new mobo for a few days, so that could've been sheer luck with damaged memory.
Other ideas: PSU is a 550 Watt Antec, I hate to think it might be the problem, but I would suppose it is possible. PSUs are one of if not the most common failure these days.
CPU might be damaged or defective.
Maybe both the AMD 770 (on the ECS) and 780 (on the Asus) chipsets suck, too.
Probably the easiest test would be swapping RAM again, but running the test (or heck, using it) for several days, rather than ~24 hours.
Thoughts, fellow geeks? I miss my quad core. I'm addicted to Fallout 3.
