Suggestions on programs to test stability?

[VovaM]

I have a E6400 @ 2800, and I'd like to make sure it's reeeeeally stable. It seems to be stable in Prime95 and Orthos, although I've only been running them for 2 hours each.

BUT, I've been noticing some strange quirks, especially when It was clocked a little bit higher (which led me to lower my OC a bit). One time the system rebooted when a friend of mine added a shared folder for us in Live Messenger. One time the GUI of Windowsblinds was corrupted when I started it. And one time I got a crash when opening CPU-Z. I'm not sure this is due to overclocking (haven't had a single problem in a couple of days now) but it seems that it might have something to do with it.

So here's the question: What programs should I run to test the overall stability of the system? Not just math calculations... I need to test other things than the CPU & RAM as well.

Windowblinds fights with Windows, and CPU-Z accesses low-level information. Occasional glitches are normal. Don't bother with Prime95, Orthos is a tweaked version and it's all you need

I just use dual prime 95 (for each core), with rthdribl for graphics and use everest ultimate edition stress tests for HDD's and ram just to throw more stuff at it. All at the same time
