I've had a lot of problem with my new computer. I've also tried everything I could think of so now I'm getting desperate. This is what I've tried so far. -updated bios -uninstalled Zone-alarm and AVG and replaced with Norton Internet Sec. 2009 -updated chipset driver -updated GPU driver -memtest 86- result ok (was on for 8 hours) -checkdesk ok -different kind of test tool from ultimate boot cd. This is a new computer with XP Pro and Windows 7 installed (different drives). System hang especially when playing iso-files with Daemin Tools even with simple games like Deerhunter 2005. Need reboot to get up running again. The system can also freeze and the famous BSOD appears. Please can anyone have a look at my dumps and tell me what next because I'm stuck right now. ****, forgot to attach the dumps. How can I do this afterwards.
