BSOD in most games after installing new GPU

Don't bump - it has the opposite effect, it will place it at the bottom of the list.

I'll look at this in the next 10 minutes.

Andrew,

Are you using Ccleaner or other optimisers on a regular basis? Running these causes the .dmp files to be deleted, which is why they aren't present in C:\Windows\Minidump

Do you recall the bugcheck code that was displayed at the time of BSOD? Without the .dmp files, the only thing I can suggest is to uninstall this tool (which is a very common cause of BSOD's):

Code:

DAEMON Tools Lite	"c:\program files (x86)\daemon tools lite\dtlite.exe" -autorun	JINX\Andrew	HKU\S-1-5-21-2850683096-181325466-2443321536-1000\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Lets see if we can force the system to BSOD again. Temporarily uninstall Ccleaner, or change its settings, then follow these instructions please:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Driver Verifier - Enable and Disable

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal and upload the new dmp file/s here.

I recommend creating a system restore point before turning on driver verifier:
System Restore Point - Create

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:
Safe Mode

Once the system BSOD's, upload the files here and I'll have a look at them again.
