Occasional glitchy mess with HD7770

[Tithis]

Been working on finally getting my cocktail machine up and running.

Initially everything seemed fine, but during tests I quickly began running into a video glitch.



So far I've only noticed this when launching games from the front end (Attract Mode) when launching from the Mame UI I've yet to run into any issues. The glitches start at the 'top' of the screen and get worse until the whole screen becomes a garbled mess. Once this occurs switching resolutions will temporarily provide a stable image before breaking down again, only thing that fixes is a reboot.

Any suggestions? Some sort of setting that might help fix it?

Any suggestions?

Might be a good idea to also post a log file.   

From Calamity's sig:

Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.Important note: posts reporting GM issues without a log will be IGNORED.

Can't seem to get my front end to launch games with those flags, instead I have a log from an instance running fine, and then another after the front end started the issue.

I tried about a dozen launches from commandline without any issue, so maybe I really  just need to find something besides Attract Mode :/ never gave me issues like this on my upright though.

edit: Ended up switching the OS from Win7 to GroovyArcade w Attract Mode and haven't had any more video glitches.

Card going bad or maybe monitor going bad?
