Hi, I'm running Windows 8 Pro.  I have a HD7970 MSI Lightning video card.  2 SSDs for space.  Every 7 hours my computer crashes and the monitor displays about 15 vertical lines across the screen...many times they are green lines but it varies into multicolored.  The computer then needs a hard reset to boot back up again as it becomes unresponsive.  I have had the video card replaced and same thing crops back up, so it is probably not the video card but some driver issue.  I have updated to the beta 12.11 driver but it seems to be a little worse than the 12.10 driver, so I use the 12.10 driver.  Any ideas or advice?I was curious when the new whql driver will come out for AMD.  Do you think it will fix this problem? 

-------------------------

you should try 12.4 to 12.6 and see if you still have these issues.Make sure after you uninstall old drivers to purge them out with a program like driver sweeper.
