I have been receiving a message on boot that; Couldn't Load HydraDMH.dll??  So I decided to check for updated drivers for my card to see if that would correct problem.  So I went to AMD and downloaded autodetect.  It then checked my video drivers and OS. It found that there was an update that should be downloaded.  It showed to download 11-2_vista64_win7_64_dd_ccc_ocl.  I went through the procedures to download and install.  Everything installed and restart computer my screen is messing up.  Lack of better terms.  It is full of vertical linesall the way across screen, and colors don't match background.  And screen is quite offset to the right.  I was connected to my monitor with Monster HDMI cable, which was working fine before download.  I disconnected it, then attached DVI cable, screen came back perfect??

Thanks for any help?

apology for forgetting that important info.

Personally, I have zero faith in the 'autodetect' thing. Use the following guide to uninstall/install the new driver suite and download the drivers from here > http://benchmark3d.com/amd-catalyst-12-10-whql . you need the dot4 version.

Uninstall your old drivers using your computer control panel / uninstall a program. Express uninstall all AMD software including the installer. Reboot. Run Driver fusion (free) http://treexy.com/products/driver-fusion  select AMD graphics and delete all it finds. Reboot. Install the latest driver suite for your card including the dotnet4. Reboot. You should be good to go.

ok, uninstalled everything, did driver fusion task, downloaded suite with net4.  I am not receiving the couldn't load message anymore. But HDMI is still not working completely.  When I try to set screen resolution to 1920 x 1080, I get the vertical lines and messed up colors??  But with DVI hooked up works just fine? 

Monitor is a Acer X233H, 23" wide screen

You did solve one problem, thank you.  But what else can I try on resolution/HDMI prob?
