Greetigs, For quite a while now I'm having these PAGE_FAULT_IN_NONPAGED_AREA BSODs. My System: Windows Vista x64 DualCore Intel Core 2 Duo E6750, 2666 MHz (8 x 333) Gigabyte GA-P35-DS4 (2 PCI, 3 PCI-E x1, 2 PCI-E x16, 4 DDR2 DIMM, Audio, Gigabit LAN, IEEE-1394) NVIDIA GeForce 8800 GTS (640 MB) Corsair 2048 MB (DDR2-800 DDR2 SDRAM) Seagate 320 GB HDD I installed Vista just a few days ago, before Vista I had Win XP installed and encountered these BSODs too. Trying to solve this problem I did all sorts of thing. Ran Memtests, zero errors. Checked my HDD a few times, zero errors. Installed different AntiVir programms, cause somewhere I read that this BSOD could be triggered by them. I still have some ideas about what might cause these bluescreens. My mainboard, cpu, ram and grafics card are all about one months old and I have head these bluescreens since I upgraded from my previous system. At the moment im using 470W power supply to run my system. I thought that mybe 470W would'nt be enough, but from what i know runnig my system with 470W should'nt be a problem. These BSODs occur while playing games, doing nothing at all just watching at my monitor and so on blablablub. I have also uploaded some minidumps. I'm thankfull for all the help I get.
