Here is my system:
Asus P7P55D PRO w/ latest BIOS 0711
G.SKILL Ripjaws Series 4GB DDR3 SDRAM DDR3 1600 (PC3 12800) F3-12800CL7D-4GBRH
SAPPHIRE 100282SR Radeon HD 5850 1GB
Western Digital Caviar Black WD6401AALS 640GB
Windows 7 x64
The problem is that the system will boot to a blue screen on cold boots. This only happens on cold boots when the system has been off for more than 5-6 hours. After a few restarts the system will finally boot into windows, but I get lots of windows explorer has stopped working errors.
The BSOD is either STOP: 0x00000050 Page_Fault_In_Non-Paged_Area or one that says that a recent hardware change is causing the blue screen.
Ive ran memtest on both auto settings and also the rams rated speed (7-7-7-24 @1.65) for about 5 hours each with no errors.
I formated a few times switched ram sticks around and quadrupled check that the ram is seated properly, and still no go
chkdsk dosent find any errors either.
Sounds like the PSU or Ram are to blame, anyone have any ideas?
