I just rebuilt my HTPC, and have been getting all the software set up. Now it's running Windows 7 x64 on an Intel i3-340 (Gigabyte H57 mobo), with 8gb ram, a 1tb hard drive and an 80gb SSD for the system drive.
Everything works quite snappily (high spec machine for and HTPC, but oh well); one problem. When I was finishing up getting things set up, I selected the "Enable GPU Scaling" box in the Calalyst Control Center, clicked "OK", and the screen went blank. The computer was still running, but the screen went blank and stayed that way.
I rebooted a bit later, uninstalled and reinstalled the driver (uninstalled while running on the chipset's native graphics, reinstalled running on the ATI in VGA mode), but it always returned to the blank screen when the driver was installed.
I tried fixing it by removing ATI entries in the registry, but just ended up rendering my machine unbootable.
Has anyone seen this happen before? I have seen some people saying that this has happened when they're using unusual resolutions, but I'm using the default 1080p resolution and no exotic settings.
The easy answer is "Well, don't click that then." :-) But I would like to know why this is happening, if anyone ever has had this problem and figured it out.
