Posted this on the ATI forums but figured Id try it here as well. This is killing me:
A little back story.
I put a new PC together and started using it on Oct 22nd (fresh Win7 64bit install) and everything has been working perfectly. This past Tuesday rolls around and I stumbled onto ATIs website and saw the ATI Catalyst Suite for Win7 64bit here:
http://game.amd.com/us-en/drivers_catalyst.aspx?p=win7/windows-7-64bit . I was running driver 8.651 and saw this had 8.661.
I download and run that, everything seems to go through ok. I reboot and start web surfing, about 10 mins later I notice my mouse cursor was huge. After some searching, I end up on the ATI forums and find that its an issue with some Gigabyte motherboards and that the most recent BIOS revision seemed to fix it. I did all that and the mouse cursor issue seems to be fixed.
This is where the problems started.
I now periodically get random "dwm.exe has stopped working" errors on startup. This disables the Aero theme. Usually, restarting fixes this and I could go for hours fine.
Another issue thats been confusing me is that everything will vanish from the screen and itll get filled with a different color depending on what programs I have open. For instance, if the error occurs when I have Steam open, the screens fills with that green color that Steam is. If I have the control panel open, it fills with that greyish blue. The only way to fix this is to shut down by holding my power button and resetting the whole system.
Last but not least, all flash videos were running very choppy this morning. This only occurred once and was fixed after reboot. However, after the reboot, I got the dwm.exe error followed shortly after by the screen being filled with color. At this point, I reboot in safe mode and rolled back the video drivers to 8.651. Reboot and again I got the dwm.exe error. For the last time, I reboot and everything started up fine. Now Im at work so I cant tinker with it until I get home.
This is what Im running with:
Gigabyte GA-P55-UD4P motherboard (BIOS f4t)
Intel Core i5 750 processor
Radeon HD5850 (Sapphire)
G.Skill Ripjaws 4GB (2x 2GB)
Antec EA 650 Power Supply
Windows 7 64bit
I regret ever updating the drivers and BIOS because that seems to be what started this whole thing. Its quite frustrating.
Any ideas? Could there be something else in that Catalyst Suite package other than the video drivers thats causing an issue?
