Hey guys I have a little problem.

My cpu running stabile at 5.1Ghz at 1.45 volt!

then I try 5.2Ghz it do.

First time it boot fine up, can almost run a 3dmark 11, then BSOD, and if I try to reboot it freeeze after it come into windows, then I can wait 20 mins and I can do the same again.
I got a big felling that my chipsæt being to hot!!

What would you say?
Temps on cpu is fine.
