ok this going to be a wierd problem just bought a new system amd phen x4 3.4ghz 8gb ram asus crosshair 4 formula 6950 2gb asus 950watt psu built system everything went fine installed windows when i installed my display drivers cat 11.3 everything went fine and my computer rebooted. after the windows 7 logo screen boom artifacts lines all over my screen thinking i got a duff card i went in safe mode and booted up at a lower resolution. i then tried to find out if ccc was doing something it shouldnt with my monitor set the hertz to 60 and slowly bumped up my resoltutions. when i got the 1680 x 1050 artifacts again, after waiting patiently for 1 minute my computer did not revert back the previous resolution, i pressed the power switch and the computer was unresponsive , i tried this soo many times same result. i then tried the different dvi port same result. i hooked up my computer to my tv via hdmi and it set it self up at a bigger resolution 1980 x1050 something like that, i then set it down to 1680 x 1050 on the tv, no problem at all worked fine. i then got my monitor plugged it in and booted the computer and bam crash again all lines on my monitor, now im tottally stuck, i have no idea how to explain this to my suppliers. is there something im doing wrong and my monitor is a 22inch hp and has worked on countless cards.
