Need help, think GPU broke

[Ghost X 710]

Update: finally got a new gtx 590 thanks to Asus

[Lesbian Dad 555]

I had something similar happen to my old 8800. As a temporary change, I just switched the DVI output to the monitor (there were two for dual monitors). The other one worked for a while before it crapped out too. Warranties are always something I look into getting something expensive, the longer the better.
