Hello. I recently upgraded my system to include two HD 5770's in crossfire. When crossfire is enables games will start but the video output is either ridiculously blurry in the menus or no video at all. If I disable crossfire the games work flawlessly but I obviously do not get the performance boost from crossfire. Also, if crossfire is enables and I restart my machine, after restart the system will freeze, every time. I really need some help here. Thanks

Specs:
Core2Quad Q8400 OC 3.00Ghz
8 gigs G Skill DDR2 800Mhz
MSI P45 Platinum HC Edition
2x Diamond Radeon HD 5770 in crossfirex
Western Digital Caviar 200GB
Seagate Barracuda 500GB
Western Digital Caviar Green 1TB
OCZ ModXStream Pro 700W

Did you uninstall any previous gfx card drivers.
Have you tried uninstalling & reinstalling the
latest ati drivers.
You said you had enabled crossfire, was this done
in the catalyst control centre.
Can you check that the pci-e latency is set to auto
in the BIOS.
Download & run gpu-z for info on how your gfx cards
are performing;

Thanks for your quick responce phillpower2, I was luckily able to resolve the problem after messing with the drivers a bit and doing a BIOS update.
