Is my system stable?

[PwnageSoul]

I just custom built a pc with 790i ultra, Q6600, 9800GX2, and 4gb ddr3 @1333. My case is an Antec120, and my cpu cooler is a Tuniq Tower. My system's randomly crashing (once every few hours) during usage. When I was overclocking, I accidently set 3000 fsb to my cpu clock speed, and my bios wouldn't boot up for a few seconds when restarted. When it did restart, my cpu clock speed was reset to the 2.40 stock speed. I was wondering if that could be a factor in my crashing? It shouldn't have harmed my cpu though. My computer crashes indiscriminately now, no matter the clock speed. It would sometimes even crash when It's idle! I currently have my Q6600 O/C to 3.38, and my idle temp is 24 degrees celcius.

Also, when monitoring my cpu frequencies, it would jump between 3.375 and 2.250 (default speed is 2.40) Why is this?

Thats called speed stepping, when your CPU is not in use it runs at stock speed, so it looks like you have it OC to 3.375GHz. Who makes the mother board.?

My mobo is a EVGA 790i ultra. I just checked the stability of my cpu with OCCT and it said it ran fine without any errors. It couldn't be my cpu that's causing it to crash (since it crashed even at 2.66.. unless it's permenately damaged). Should I overclock my cpu even more? It's currently running on air @3.38ghz, idle temp = 25.

PwnageSoul, kill speed stepping in BIOS, you’ll run full OC all the time then.

If you want to know if you have damaged your components which i don’t believe you have... run the machine @ stock settings in Prime95 for a few hours.
When it passes Prime95, up your FSB and test with Prime95 again. Rinse and repeat until you crash and then drop it down to the last good OC.

Also, is your memory linked to the Processor? If so unlink it, set to default voltage and CAS.

Disable speedstep in bios and remove all but 1 stick of RAM.If the system remains stable for twice as long as before without any errors,then add another stick of RAM.Also,you forgot to mention what POWER SUPPLY you have.You should have a 750watt PSU or bigger of a quality name brand.Goodluck.
