So I updated my laptop to Windows 10 and despite lack of official support it had worked OK for many months.
A few weeks ago though I got a sudden blue screen
Video tdr failure atikmdag.sys. With massive amounts of graphical artefacts on screen.
Tried Google and many hours of trying to get a working driver without success.
Did a memory test. check disk etc and they seemed fine
Eventually reinstalled win 10 from scratch but had problem straight off but couldn't do anything after that without getting bsod.
Tried going back to win 7 and whilst better has already has bsod re the same thing before even having the updates completed
Edit.. Also tried opening and cleaning it all but no change. Didn't go under heat sinks to GPS though as bit more involved
Is all lost? It's old but was still fine
Surely can't be driver if still crap with clean installs on two OS?
Cheers for any help
