Green lines with 7800gtx

[Blistered]

Hi!
I just got my new pc today, but when i ran 3dmark there was a broad vertical line on the left of the screen and a horizontal green line running across the centre. No matter what game i try and run the lines are there, but they don't appear while viewing the desktop.

my specs are:
asus a8n32-sli deluxe mobo
2 x 1gb corsair ram
2 x bfg 7800gtx 256 (sli)
SB X-FI PRO ELITE
ACER AL1721 LCD monitor

Any ideas? It's really frustrating as my pc has literally just been put together!
Any help would be greatly appreciated 😀

which driver you using?

Are you using the SLI bridge, or not?

In the nvidia settings there is a checkmark to turn off the green line.
Since you are running sli the line shows the screen split for which each card is rendering.

Disable show GPU load balancing.

Cheers for the help!
I thought there was something very wrong with the cards!
All sorted now! I was also having trouble with F.E.A.R, but I intalled the latest forceware(?) release and it's running so well, it's unbelievable!

Thanks again!
