Confounded and Boggled...

Hello all!

As the title says, I am both in regards to the state of my computer. Over the past 3 months, my computer has especially disagreeable and the source of my troubles has perpetually eluded me. I am desperately searching for clues as for what could be wrong with my randomly BSODing, freezing, glitching computer.

Here is my current/recent config(s):

E8400 OC'd to 4.25GHz(8.5x500) 1.3625Vcore, now at 3.6GHz(9x400) 1.3Vcore.
Gigabyte EP45-UD3P motherboard
Mushkin 996580 2x2GB, was at 1000, now at 800MHz.
2 x Sapphire 4870 512s, stock
2 x Western Digital WD1600YS Raid 0, has been in Raid 1 also
Seagate 500GB
PCPAC Silencer 610
XP Pro x86, Win7 64bit, Vista HP x86(current)

Okay. So in recent days I have had Win7 x64 installed on my comp, wanting to skip Vista entirely for a better version of the same. Initially pleased, I soon was boggled by the instability i found there getting several BSOD's per week related to Page Fault in Non Paged Area and Bad Pool Header relating back to dxgmms1.sys. I promtly researched this on Google after the 3rd time this occurred, finding that this was a 3D related file. I found this curious, since I would get this error while browsing the internet and listening to music as much if not more than while playing COD4 or Left4Dead2. I also thought it could be related to my overclocking, so i scaled back to 3.6 which found my proc prime95 rock solid for 28 hours, small FFTs. As the errors persisted, I continued to scan my memory with memtest86 which completed 18 passes over 20 hours unscathed. After my seagate 500gb drive suddenly decided to commit digital homicide and murder all my backup data and music, I thought surely, /surely/ it was at fault! Absolutely not. Even running diagnostic tests on my WD drives returned perfect results. Fed up, I absolved that it truly was a Win7 incompatability that my woes drew from.

Which brings me to where I am now, under Vista x32, still experiencing some of the most random, wierd problems(far more diverse than even within Win7x64) I have ever come across(like the sound just going out for no reason while listening to music and playing COD4 and not returning until i restarted, win updates stalling,failing and then after a reboot working, etc.). So then I sighed a deep sigh, believing that my trusty PCPowerandcooling PSU had gone bad. As the next step, I hooked up my DMM to it to measure voltages as I played COD4 briefly to percieve any major hiccups- I found nothing. Barely a budge of .02v on the 12v fed to my 4870.

And so, I am at my wits end trying to figure the damned problem out that seems to be nothing but a ghost in my computer, intent on trying my sanity! PLEASE HELP ME!

Set your clock speeds back to stock settings and run your diagnostics again.

Okay- I reset all clocks, voltages and other OC settings to stock and ran Memtest86 overnight for 8+ passes: no errors. Also, I separated my WD 160GB drives in RAID1 by disabling RAID, and ran WD LifeGuard diagnostic on both with no errors. My proc is still %100 under PRIME 95 as well.

I am willing to try ANYTHING at this point. Even though I used a digital multimeter to test the voltages of my PSU under load, all things still point to it(or the motherboard, but I doubt it b/c its only like 6 months old) being the culprit(after all, it is nearly 3 years old). Yet, the next best PSU I have available is a 4+ year old Antec 450W thats been used 24/7 for about 3 of those years... Anyone know of a way to test it without buying a new one?

Are you using the stock drivers that came with the motherboard or did you go online and download the drivers that are compatible with Vista/Win7?

any bulging caps on the mobo?

had a biostar mobo give similar errors, found bulgy caps, replaced mobo with exact same kind, no more blue screens, didn't have to reinstall anything.
