....not the fault of Windows 8 preview, as it happened before I put it on. BUT my graphics card - I have 2 in, a Radeon 6670 and an earlier Radion 4750 I believe -the 6670 frequently blacked out the screen, so I gave up and went back on my older one. Which didn't have the black outs. But yesterday I was on Steam and they now apparently look for driver updates for you. Great sez I. Upgraded, and now my older 4750 has blackouts too !
What the hell is going on ?
(If you feel this should be moved, by all means do so - just desperate)
