The following software issues are examples that can cause a TDR event:
-Incompatible drivers of any sort (either GPU, sound, etc)
Windows Compatibility Center: Find Updates, Drivers, & Downloads for Windows 8, Windows RT and Windows 7
-Messy registry (
I doubt this and don't approve of registry cleaners)
-Known vista issues resounding around multiple displays, aero, dreamscape, and various display drivers. (
none known for Win7 - but in early to mid-2012 there were some reported issues w/ATI drivers)
-Known vista issues that sometimes cause corrupt information to be sent to the video card from system memory (will be addressed completely in SP2, has had various fixes applied since vista's release) (
none known for Win7)
-Bad direct x files (
uninstall, then reinstall DirectX)
-bad system files (
System File Checker - was run above)
-Bad driver (some drivers will cause an event due to internal bugs, however these are not nearly as common as many think due to all of the previous things causing the same symptom) - (
remove all 3rd party programs and check to be sure drivers aren't loading. Then install only the necessary 3rd party stuff, and ensure it's the latest version and that it's compatible with Win7)
