Hey guys, bought a new pc about a month ago, and I am having some problems with it, I keep getting BSOD's with different errors, sometimes it's win32k, sometimes it's IRQL not less or equal, once it was dxdmms1, once system service exception. I was running windows 7 x64 enterprise edition, but I read some reading around here and you guys said that the x32 version was more stable, so I installed it today, and while I was trying to install AVG free edition, I got a BSOD with the attached mini dump. My pc config is as follows: Asrock 890GX Extreme3 AMD Phenom II X6 1055T Kingston HyperX dual channel kit 4gb 1600 cl9 240 Samsung Spinpoint F3 HD502HJ 500GB 16MB Nvidia Quadro FX 580 Corsair CMPSU-400CXEU 400W I sent the pc in the warranty service, but their luck was that in the same time a s-ata cable failed, and they changed that cable and sent the pc back, claiming that was the only problem. Desperetly need your help, I work with 3d studio max as a freelancer, and I have a very angry client waiting for me to finish his project, but I keep getting random BSOD, and it pisses me off. Thanks a lot for your time and effort. Edit: I forgot, I tried unplugging the video card, and using the onboard one, it still gave me BSOD, so I don't suspect the video card. Edit2: Just got a new one whyle browsing: PFN list corrupt: here is dmp file Edit3: Fresh BSOD coming up! Never got this one until now, MEMORY MANAGEMENT: dmp file attached.
