I have two computers. Yesterday I hooked up my newer pc to my old ones monitor/keyboard etc to diagnose a seperate internet issue. I really wish I hadn't.. I had to use a dvi to vga adapter to plug into the graphics card as the old PC's monitor only has VGA. When it booted it asked me to load new monitor drivers which I did. It didnt help me diagnose the problem so I took the PC back upstairs to my new PC and monitor... BUT when I hooked my new PC (Asus P5Q Pro Turbo with msi 8600GT-OC) back up to my new DVI Relisys TL795-RU monitor with the DVI cable it gives a terrible green/yellow garbled display with lines and flickering. Also it doesnt display anything on the initial post boot screen until the XP logo or if i press del and wait for bios to show. However, it works fine if i use a a vga cable with dvi adaper in the graphics card as I did on the other P.C What's going on?? I dont want to have to use VGA as the display is not very clear. It seems as if the card has been altered to VGA and doesnt want to switch back. I've tried uninstalling nvidia and monitor drivers but it doesn't help. I think the problem is deeper than that because the messed up graphics happens even in the in bios. I'd really appreciate some help, as this is the latest in a long line of problems, I'm at the end of my tether.....thanks btw ignore my specs as i cant rescan on this P.C

check if video cable is bent also check every connector around there

The cables arn't bent. I don't currently have other DVI monitor or cables to check but i'm curious whether the problem is with my graphics card or the the monitor or even windows although I get the problem in the bios too. below is an image of the screen, it flickers constantly. When i plug in the dvi cable to it takes maybe 10-20 seconds to get this screen, the monitor seems to try to find the right settings http://img36.imageshack.us/img36/13...

I just tried a brand new cable in, same problem.

reinstall the graphics driver if doesn`t work try disabling the graphics card temporarily and the enable it again

also try this... right click on desktop >> properties >> settings tab >> set color quality to highest...

it's already at the highest, anyone else got any ideas?
