I suspect my PSU or WiFi card but here is some info and minidumps. Brand new install of Win7 Ultimate x86. The setup: Intel Pentium D 945 @ 3.4 Ghz, Gigabyte 8I865G775-G mobo, Nvidia 7800GS AGP, 4x512MB Kingston @ 400 Mhz, TP-Link TL-WN951N Wi-Fi internal PCI card, 320GB HD WD SATA, random unnamed 500W PSU. Any help appreciated. Thanks for your time. edit1: as i did some research for my TL-WN951N wifi i ve seen some people having issues running it under win7 since there are no signed drivers for the OS. i just want some info on the minidumps so i can figure out what's going wrong.
