I sounds like video card first thing to do is try reseating the card. Use driver cleaner and wipe all video drivers then install the latest catalysts. If that no workie then try to rma your card.

I think your video card is fucked up . I know because it happened to me before. ı had got a 5700le. ı put an aftermarket cooler on it but it had not been contacting to the gpu( ı learned it when it was too late) ı was overclocking it and after a while thouse vertical lines appeared even in bios screen and my video card was dead :)

if you did not oc-ed it ...it`s probably a heat issue........open the case and clean the cooler.....also keep on eye on it......old coolers usually get stucked also...
good luck
