View attachment sfdiag dumps.zip Hello I started a custom build about last December. Within two days of the first power up I started having problems. The system would just freeze up and the speakers would emit a dull tone. Did some research and discovered that it was most likely a RAM problem. I missed my return window so I was faced with possibly dropping another $100 and getting new ram, but the wife wouldnt allow that so I tested the crap out of my current ram and kept getting the same result... no problems found. Ok a few months go by and I get some more free time so I start working on it again. I would have probably a 10% chance of a smooth boot and error free time using the computer. When I would shut down at night and go back in the morning to play around I would get blue screen after blue screen. I orginally had it set up with home premium 64 but was having a couple problems with some of my older programs and thought maybe the 64 portion maybe causing the blue screen problem, so I installed the 32 bit version. After installing all ms updates (with multiple reboots) and an antivirus I still didnt have any problems so I made a restore point. Shut down computer and turn on again the following morning and BSOD once again. Im at my wits end. I want to take a sledge to my beauty but I know my wife will kill for wasting almost a grand on it. please help. Problem: BSOD - Memory management, page fault... nonpaged, bad pool header occasionally during safe mode as well Recently I have tried: Clean install of home premium 64 Clean install of home premium 32 registry cleaners memory testing - result = no problems memory swapping - still BSOD turning off XMP - had a good session immediately after i switched it off, on next boot up windows failed to start and I had to run windows startup repair about 4 times. trying different antivirus - first MS security essentials, then Norton Security suite from comcast various other suggestions from these forums over the past few months My Build: Intel Core i5-750 Lynnfield 2.66GHz LGA 1156 95W Quad-Core Processor BX80605I5750 Western Digital Caviar Black WD6401AALS 640GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL8D-4GBHK ASUS P7P55D PRO LGA 1156 Intel P55 ATX Intel Motherboard MSI N260GTX-T2D896-OCv3 GeForce GTX 260 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card I dont know what other info to give you all, but I hope you can help.
