Hello, I keep getting BSOD about 5 minutes after opening a game. I tried many things to stop this, but it just keep crashing, with different causes. I tried Memtest86 and it says everything's OK. I downloaded the Drivers Pack Solution and same thing. I made it crash many times and after fixing a thing it crashes by another cause (first IRQL not less or equal, then Page fault in nonpaged area and now it says NTFS file system). This is a new computer, I only could play once, and then the second time it crashed. It happened with Devil May Cry 4, but I installed Assassins Creed II and it does the same thing. Specs are: Windows 7 Ultimate AMD A8-3780 APU with integrated Radeon HD 6550 D Motherboard AS-ROCK AA55M-HVS RAM 8192mb DDR3 Power Supplies: 230V 50/60hz 500W By now the dump says it's caused by AVG (I think) but I guess it won't fix by uninstalling it. I've got many dumps with different causes of crash, but here's the last one: Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64 Copyright (c) Microsoft Corporation. All rights reserved.
