I have a Dell XPS 420 which i recently upgraded with a EVGA GTX 550TI and a 80GB SSD Drive. I converted this machine into a home theater PC. Which I've always had on.

The computer wasn't responding, and so i restarted it and when it started, video ports showing static. I was getting static on my TV thru both DVI ports and the mini HDMI port.

I assumed my video card had gone bad, but i completely replaced it and still the same behavior is occurring. I do not know how to diagnosis this issue. Any thoughts?
