Help: Monitors don't show visuals

Dual monitor setup. Samsung Syncmaster SA450 (main) and a samsung 20C300L (2nd). Both connected via dvi.

2 weeks ago my gtx580 kacked it after 4 yrs. Today i put in my sisters old gtx630 just so i can use the comp. When it was in, we hooked everything up and there was no picture.

I then took it to a friends house (he's in the know). Hooked it up all worked fine (via dvi) after motherboard identified it as the dedicated graphics card. Single screen.

Drove home, 1 hour later all set up and no picture. It was just working and now theres no visual on either screen. The computer works because i could hear skype load up and can play music (spotify loads at startup and my keyboard has a play button).

So i call my friend on skype via laptop and we try a few things.

dvi or vga dnt work on either screen.
vga to TV doesnt work
vga - laptop works on main screen only
used different power outlets, no visual
used brothers monitor, no visual

hdmi - tv works BUT vga from tv - monitors does not give a 2nd screen nor can 'screen resolution' identify it.

This is where we call it.

After the call, i go to setup my laptop - main via vga so i can still have 2 screens and do stuff, but now that doesnt want to work either.

Do i call an excorsist?
