Graphics artifacts

[holy god of nil]

Europa universalis (http://en.wikipedia.org/wiki/Europa_Universalis_III) which is seriously un-graphically intensive and used to play perfectly on my old system, has nasty artifacts in normal play since I upgraded; black and yellow lines shoot across the screen at random intervals. My gpu, a 7850, is furmark stable and I have up to date directx and amd drivers, I have no idea what might be causing this?

I was thinking maybe the new directx/drivers might disagree with it but can't think of any way of troubleshooting this (other than installing loads of old versions of drivers which doesn't sound tempting)

Test it in another PC if possible

what driver version you using

and do you have any overheating issues within the system

???????

Aye I will test it out in another machine but I'm struggling to see it being a hardware issue really.

System runs very cool, idle temp of the card is only 33, didn't even top 67 in furmark. Running catalyst 12.8.

Is it overclocked? with my sapphire 7850, if i even overclock it to just 900 mhz, it runs stable in furmark, heaven, & 3d mark 11. But when I went to play dirt 3, the strangest thing ever happens, the headlights of the car illuminating the road flicker on and off.

It's the overclocked version, which I have also overclocked further yes. However running it at the cards stock clocks (still over a standard 7850 obviously) it still seems to happen. Will have a good go at working out what's going on this evening.

I would try unplugging any hardware that isn't needed. Just incase something is causing a problem with the drivers.

You never know. Hardware issues can present them selves in funny ways sometimes.
