Hi Osprey.
Thanks for the tip.
I have run the dxdiag at the moment and have only got a "not digitally signed" file note, full text below.
Would you have any suggestions at to what programs would be good to fully test the diagnostics?
I have seen some suggestions of Memtest86 and Prime95 in the forums but they don't seem to be video card specific, I will probably run these anyway just to check that there is nothing going on with that also but if you have any videocard diag tools you could recomend to run I will run those also?
The full note from dxdiag:
The file atiu9p64 aticfx64 aticfx64 atiu9pag aticfx32 aticfx32 atiumd64 atidxx64 atidxx64 atiumdag atidxx32 atidxx32 atiumdva atiumd6a atitmm64 is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.
Thanks for your help and suggestion.
