SOLVED: Windows 7 PC keeps randomly rebooting

[Paladin]

Over the past couple days my PC has been randomly rebooting. It blue screened once, the other reboots are completely random. I need some help in debugging.
All Windows updates are current. I haven't updated my video or audio drivers in quite a while (4 months).
There is a memory dump, what is the best way to analyze?

Any help is appreciated.

I use this:

Quite good at finding which driver or event caused it. No need to install anything, just unzip and run the exe.

Although last time I had your issue, it was a bad stick of memory.

Sounds like it is overheating because the CPU fan is frozen or clogged. Or a bad power supply. From my experience, these are more likely hardware than software. Intermittent memory failures are by their nature completely random.

I'll check the heat, and blow out my fans. I'm usually pretty good at keeping them clean, though now that I think of it I haven't done it in a while.
My first thought was RAM stick also.
Also, it's done a disk check twice tonight.
I'll try that download.
Any other hints are appreciated.
Thanks

I went into the bios, and looked at a few things. On one page it stated:
"The system has experienced boot failures do to overclocking or changes of voltages"
I haven't changed anything, and looked a the settings, and they are still default.
Sound like a power supply issue?
I tried removing one or the other sticks of RAM, no joy.
The system only stays up now for 10 minutes max. Then reboots.

Sounds like a power issue to me. That "changes in voltage" warning despite not having overclocked- I've seen that very thing occur with a failing PSU or a severe brownout condition in the home wiring. Basically the BIOS doesn't know the source of the problem, just throws up that error by default.

I'd check the PSU (if possible use another one temporarily and see if problem persists and/or check if you might have an electrical issue elsewhere causing irregularly in the power. (Best would be to use a UPS or decent surge protector and see if it persists.)

I assume you did check the CPU fan, PSU fan, and temps? No excessive dust anywhere? Check all connections seated properly and attached perifs including internal/ external drive connections?

Also can't hurt to clear/reset the BIOS.

I went to Best Buy and picked up this:corsair-cx-series-modular-cx750m-750w-atx-power-supply-black
It had good reviews there and at Newegg. Installed and the system has been up for an hour with no issues so far.

Thanks everyone
