BSOD pagefault in nonpaged area 0x00000050 ntoskrnl.exe+75bc0

OK, thanks essenbe. I'm going to install the new video card I have on hand and see what happens. I will keep you updated.

Replaced xfx R9 270x with a brand new Power Color R9 280 (not my favorite brand, but got a good deal). Just to be safe I uninstalled all drivers and ran Display Driver Uninstaller before I installed the new card. New drivers directly from AMD site. I'll run Furmark and monitor temps and see if any more BSOD's.

Sounds good. Let me know how it goes and the temps. They are supposed to run pretty hot. I bought a Powercolor 5770 when they were new. I use it for a backup now, but it's still running. They are not that bad.

Well, so far so good with temps. The old card idled at 32 degrees C and maxed out at 95 degrees C on furmark. New card idles at 30, and maxed out at 73 on furmark. So, I'm impressed with the cooling at least.

Too early to tell on the BSOD's, but I'm hoping for the best. I've already replaced the power supply and mother board, so unless it's the CPU or RAM, I've pretty much replaced everything else.

You ran memtest which tests the ram, and I think you ran Prime95 which tests the CPU. Trust me, just because it's new does not mean it works right. I'm glad it is working out so far and hope it continues. Let me know the outcome.

Indeed, will do, and thanks again for all of your help, Steve.

Well, another BSOD. Attached dump file. Is mother board next to replace? I've literally replaced everything except CPU and RAM. Memtest 86+ passes 16 times with zero errors.

I should add that with prior motherboard (Asrock z87 extreme 4) I did not actually have any BSOD's, but the system froze up quite regularly, I guess what I would term as black screens of death. CD drives would open, mouse light on, etc., but monitor black and system would not respond--would require hard re-boots.

I suppose it's possible I've gotten 2 bad motherboards, or perhaps some of the other fixes would have resolved the Asrock board issues? At this point, unless the dump files point to something else, I'm going to RMA this ASUS board and reinstall the Asrock board and see what happens. Let me know if you have other suggestions. Thanks much.
