hey there guys. i am using win 8 x64 and i have XFX GT240 1GB DDR5. the issue is since the driver update to 301.42 all the other latest drivers are not working properly. I mean i am having continuous screen flashing with windows warning sound. looks like the GC is turning on and off at the same time. i havent played any game with this issue yet becoz this problem itself is a big mess. but when i roll back to 301.42 everything comes to normal. now the need is that 301.42 is not properly supported with win 8 so i need to update it at any cost. please suggest a solution.
