Exorcist Wanted. Inquire Within

I came back from the Oak Ridge Playhouse's 60th Anniversary Gala last night, nudged my PC's mouse, and discovered my monitor has been taken over my demons.

All I can see is a dim, glow with barely legible words, and horizontal streaks across the screen like an old RCA with bad reception.

I tried reinstalling the driver, no help. I switched out with my son's monitor, and same thing on his. Apparently something must be hosed with the graphics card (gack!) because I've ruled out cables and the monitor itself.

So anyway, please forgive any mispellings - I can hardly see what I'm typing - and if anyone knows a PC witch doctor who makes house calls, please let me know.
