Solved Troubleshooting guidance for custom-built PC

Microsoft Windows 7 professional 64-bit

Specs: W7 Pro 64 bit, AMD triple core/4gig
2 years ago I built this machine:

mobo: Gigabyte GA-MA 790XT-UD4P
CPU: AMD Phenom II X3 720 triple core 2.8 ghz
Memory: Corsair XMS3 DHX DDR3 PC3-10666 1333 mhz CAS9 2 x 2gb
PSU: Coolmax (sorry...don't know model)
OS: W7 pro 32 bit

Everyone once in a while - maybe 1 time every 3 months - I'd notice first thing in the morning that it had rebooted itself. Didn't really think much about it.

I decided to put in an SSD and W7 pro 64 bit. Now started seeing problems more often. Had lots of trouble using mouse, like when a process was eating all the CPU cycles. Then computer rebooted itself twice in period of 3 hours, complete with BSOD. Talked with MS about error message shown, they said it indicates memory problems.

Then machine wouldn't boot at all, not even POST or BIOS. Took it apart and bench tested. Could get to POST so tested with 1 stick of memory in each slot. Machine worked in each config. Put back together and running.

Not sure what my next step should be. If I buy new memory, install it, and the problem is CPU or mobo, could it damage the new memory? Could the problem be a short in one of the cables from the PSU?

Any suggestions on how to proceed greatly appreciated.

Temps, bios settings, voltage issues, esd damage.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Kuwese, thanks for the heads up on memtest!!! I burned a DVD, booted up, ran the tests and the memory bombed!! I'm doing further tests but it looks like I'm getting errors when 2 sticks are in but none when just 1 stick is in. And the sticks are exactly alike - go figure!!
