Random bsods, tried almost everything!

[Duvelduvel]

Hello,

Well i did remove X.M.P ofcourse cause i could not boot, and with a processor on 2.6 QPI of 1.23 should be enough.

The strange thing now is, i did set my processor to dual core last night and since then i dind't crash or "freezed" in a game yet.
So now im running at 2 Cores, also the Prime95 is going quite good (did multiple blend runs (even while running a game)) and it did not bsod on me and also not crash/freeze the game.

The only strange thing now is that my mouse cursor is bugged, some graphical glitch, quite strange and this happend 5minutes ago btw. (temps are all fine)

The thing is, i guess ill put it on tonight again (all of the cores) and see if it starts crashing again, but then i still don't know if the motherboard can't handle the 4cores or it is actually some defect on the 3/4th core?

I did not hear much about broken cores on i7.

And yes, i will try to contact my dealer to test it out i guess.
But untill then i hope to find actually what the problem causes :<

Thanks for your time again.

And btw:

My memory is OCZ Gold 1600 MHZ 8-8-8-24 and runs on 1.65v as default.
My psu is a 750 watt corsair.

Interesting that it runs on two cores, everything sounds like a CPU issue but, power (PSU) can cause the multiple issues you are having.

If you can get another PSU to test with, I think it might be worth doing.

Asking to reduce the RAM frequency and timings to see if it will become stable, which may indicate memory controller problem, if the memtest86+ passes.
Dosen't matter what the RAM is rated for, since you have backed off the CPU and are still having crashes you need to back off the RAM and memory controller load also.

Lower frequency and voltage on everything then bring one component up at a time to see if there is an indication of the cause. The trouble shooting method is similar to OC'ing, find the limits/failure points for each component.

Ram failures are the most common, so usually it's a good place to start, be systematic.
Rule out one component at a time.
The shotgun approach will work sometimes, if you're lucky.
