Can someone help me out with this problem please? I have built a new PC, and it’s been unstable from the first day I powered it up. It constantly fails with a BSOD, (PAGE FAULT IN NONPAGED AREA is the most frequent error, but by no means the only Stop error). Some basic details; Gigabyte EP45 UD3P (Bios version F9), Intel E8600, Samsung Spinpoint 1Tb, 4Gb G.SKILL DDR2-800 [F2-6400CL4D-4GBPK] (CL4-4-4-12 2.0~2.1V), ATI Sapphire HD 4830, Cooler Master 460W PSU. Not overclocked. I ran the Microsoft mtinst memory test utility on extended test mode for 9 hours without fault. I have removed and re-seated the RAM. I have resized the Pagefile and defraged the HDD, with zero success. Minidumps are attached. Can somebody help me out…? Appreciate it, Paul.
