Desperate need of help - i7 920 OC

Please please help !

So basically I am experiencing system freezes randomly while playing games or idle, doesn't matter which.

I had this system 100% stable with a 24 hour prime test only two weeks ago. Only two things have changed:
I got my 7970, and I moved my pc to my new house. So I tried messing around with every voltage and setting I could to get my 4 GHz stable again when the system started to freeze (there is no BSOD).
Now I am running my system at safety defauts, my RAM is 1066, my CPU is 2.66 GHz....basically everything is auto, I even droped the overdrive OC on the GPU, though I really doubt this is the issue.

My specs are in my sig, please if you can give any advice on what this may be, have I pushed too hard? I'm just going to buy a 2500k if this keeps up...

No problem if you need any more info!!!

Thanks in advance,

  1. What cpu cooler do you have? what voltages did you try? What temps were you getting? more info.
  2. I have the i7-920 DO and it is OCed to 3.82 GHz; very stable. I know that CPUs will vary depending on die location on the silicon wafer.

    I OCed mine to 4.0 GHz and after running it at 4.0 I decided to back it down to 3.82 which in itself is a nice overclock.

    Since you are quite familiar with overclocking, why not start over and OC until you start to have problems? Then back down a little.
