Been using the P5Q Deluxe for a while now and it's been nothing but finicky (although the features are great). I figured maybe I could get some help stabilizing this thing if I posted some details about the problems so here goes:

My rig really hates cold boots - usually I have to shut the psu switch off then back on again when I'm turning it on in the morning. I do have some random crashes but they're very infrequent - the cold boot issue is the most obvious one. I'm running 8x420 with ram @ 840 / 2.1V that passes memtest all day/night long at those settings so I don't think the memory is the issue. I also don't think cpu voltage or OC settings are necessarily the issue, because crashes take place randomly - like I can run Prime95 for 24 hours using all four cores with total stability then I'll get a critical error while surfing the web using firefox.

The only thing I can think of is that I installed a new PSU - the corsair 750TX - with this motherboard. If I check my voltage the cpu voltage is showing up right, but the rest look kind of funny. Could the psu be causing my problems?? The rest of my voltages according to speedfan are:

3.3V @ 2.95V
5V @ 6.044V
12V @ 13.31V (fluctuates)

The rest of my specs are in my signature. Any ideas on troubleshooting this? Should I send my psu back? Could it be my motherboard / OC settings?

EDIT: Just upgraded to 803 bios and still having cold boot issues / random crashes.
