Ok it just happened again.. going to contact pk about this..
I looked at your uploaded memory dump, and it was a fault in your video driver (i'm really not sure what's the reason)... you can try to update your drivers or check hw/installed apps. Or wait for another dump - once you get it, upload it on our ftp, and email me.
tech details from dump:
nt!KeBugCheckEx
dxgkrnl!TdrBugcheckOnTimeout
dxgkrnl!DXGADAPTER::Reset
dxgkrnl!TdrResetFromTimeout
dxgmms1!VidSchiWorkerThread
nt!PspSystemThreadStartup
nt!KiStartSystemThread
- you can try to google "TdrBugcheckOnTimeout" and read some posts on this topic
