I purchased the MSI 4890 Cyclone OC and whenever I launch a video or video game it goes black like the monitor was in standby mode. Audio is still playing, but I can't do anything unless I restart the computer. Sometimes it will flicker first then go all black. All video clips show artifacts or some kind and black and white line streaks horizontally across the display. A couple times it would give me the BSOD.

I did everything I was suppose such as wipe out old drivers, install latest drivers (9.8 catalyst), temps are good, etc.Both DVI and RGB connectors do the same thing.

What's going on here? This card has given me nothing, but headaches. Any help would be appreciated!

Try decent PSU not Ultra's.
With solid single rail with at least +32A @ +12V {Corsair VX,TX series}

My Ultra's power rating is 34A @ 12v. Besides, I tested with a multimeter and it doesn't go below 12.02v during heavy loads.

Test VGA in another machine then, as i doubt in Ultra's quality.

I did and it is doing the same thing. I have been reading around and other 4890 owners had encountered this problem.

I click on a video file and it would freeze up to a black screen, and throw me VPU recover errors. Temperature 52c.

This thread describes exactly what is going on with my card:

Have you done a new fresh OS installation? There could be some mess.
Also try VGA drivers from MSI web for your VGA and latest drivers from ATI.
If no change seems something is wrong with the VGA.
