AMD/ATI Windows 7 x64 BSOD atikmdag.sys
I've just built a new machine and a problem has reared it's ugly head and it sounds like it's a common one with AMD GPUs.
Every now and then (usually when watching a video or if I change the input on my TV) I get a BSOD. Examining the minidump, atikmdag.sys appears to be the root, suggesting some issue with the GPU.
I've tried numerous fixes I've found online, including reinstalling drivers, registry hacking the TdrDelay value, underclocking the GPU. None seem to have worked (though I thought TdrDelay had as the problem went away for a whole day)
Next step is to try removing a stick of RAM as that's been reported to work but if that is the only fix, this card is going back. Ridiculous compromise.
Any regular AMD users experienced this issue and if so, do you know of a reliable fix?
