Stable bios settings for ga-p55a-ud3, i5-760 and 1600 mhz 1.65v ram?

The current build I have has windows 7 64 bit installed and I've been trying to install the windows updates but every time it freezes or reboots (event 41 kernel power) while downloading or installing the patches. I'd like to get this computer to be stable, I wonder if it's the bios settings causing the problems.

The computer can run chkdsk or sit in bios just fine without problems although for a while I would sometimes start the computer to see random black lines through the bios/windows boot screens, usually on the first boot of the day, but rebooting it would get rid of that problem.

Settings I've tried are...
fail-safe with and without XMP1
optimized with and without XMP1
fail-safe with XMP1 and QTT changed to 1.17 and 1.19, and CPU VCORE to 1.3
And some of the above with Advanced CPU Core Features C1IE, C3/C6, Thermal Monitor, CPU EIST disabled, hard to remember which ones I tried with these on/off I should have wrote it down

Other things I've tried are...
chkdsk, no problems
memtest86, about 9 hours, no problems
furmark, the gtx 460 runs at 98-99 c but makes it through the test
rma motherboard, also tried using asus p7p55d-e lx
reinstall windows 7 64 and drivers thru clean install, also tried an upgrade installation
temperatures, cpu runs idle around 25-32C and isn't past 40C when freezing, video card around 38-48C in windows unless gaming
using a radeon card, i can't remember the model number but it was $75

gigabyte ga-p55a-ud3 rev 2.0 bios f11
i5-760 with hyper 212
corsair dominator 2x2 gb 1600 mhz ddr3 "C9"
gtx 460 1 gb
antec truepower 750 watt
samsung spinpoint f3 1 tb, passes chkdsk no errors
sound blaster xtreme music
haf 922 case
asus dvd

Long story... This system has always had random freezing ever since I first built it a year ago, it usually happened either while loading windows 7 or while I have a few tabs open in windows explorer. It rarely happened while gaming. A couple weeks ago, after it restarted on its own, it kept freezing in the windows 7 loading screen over and over until I left it off for a while. But then it did the same thing again, where I couldn't load windows after a random freeze or restart. Maybe windows was corrupted but I tried using an asus p7p55d-e lx motherboard with the same parts. Sometimes this motherboard would first boot with black lines through the bios screen and windows would load into safe mode, and this one froze a lot less often but still randomly froze in windows, and since I rma'd the other motherboard and they said nothings wrong with it, the only thing left for the motherboards is either that the p55 chipset doesn't work well with the video card or ram or their combination with windows, but I was hoping someone on here had these parts and got it to work so I could copy their bios settings to rule that out.

    Perhaps we can work together on BIOS settings.
