I have a Dell Studio 1555. It was running fine until a few dozen people started inserting their flash disks in and out. First it got this dwm.exe error whenever I played games. I fixed it by disabling that thing. I can play smoothly now, but not up until recently when a BSOD popped with an ataport.sys. I'd run a lot more tests but I figured I'd show the minidump before doing so, just to get a quick opinion before I get into some uneeded processes to solve this. I'm hoping its just a rootkit, but I have no idea how to know. If its a hardware problem, I'm f'd. Thanks guys.
