So I woke up this morning and booted my PC. The screen remained black even after the computer was on, "No signal" appeared on the screen. So I of course restarted, no dice. Next step I took was to unplug the monitor from my GPU and back into the default slot for the built-in graphics card the computer used to run off of. The monitor then responded and I was at my desktop.

I was able to readjust my resolution back to what it was, however when attempting to run WoW the FPS must have been less than 1. Of course this is because the monitor is now running off of the old card, which can't handle such resolution settings. My problem now is getting my GPU to work again. My computer only has one slot that it fits in so trying a different one is out of the question. I went into the device manager and my GPU isn't even coming up now, only the built in one that it is currently running off of. So is my card dead, or is there something else I should be doing?

Specs:
