Green lines when running 3d mark?

[TheEnosFam]

When i run the free version of 3d mark 11 I get to GPU test 4 and then my screen has these olive green lines / bars going up and down and my PC freezes. Trying to see what the problem is and if i need to RMA as the card is only 2 months old. Card is a HIS HD 5770 running it on a Asrock M3A770DE Mobo with AMD 1090t BE - 4 GB OCZ 1333 gold - CIT 700 PSU . If i remember correct the temp was about 58c when this happened so i don't believe it s a over heat problem. Any help would be great.


Thanks in advance.

It may be your PSU. have you got a spare one to test?
Is it just 3d mark? Does it do this in games? Also, try heaven and see if anything similar happens.

It was doing it in Game but then I turned the settings down a notch and it doesnt seem to do it any more. I am hoping it is my PSU and sadly I do not have another one to try at the moment. I will try Heaven and report back. Thanks.
