Hi, I got a pretty old GPU as you can see. I was gaming the other night, suddenly it throws me off a game, black screen, couple short beeps(5-6), then PC goes for restart. I was running two screens, "Maximize 3D performance" is ON (multi gpu ). After restart on a login screen/desctop I see artifacts on both screens, freezing for second or two, screen blinks, seconds later screen goes BSOD saying "Video Scheduler Internal Error". I disconnected my other screen.(there are 2 DVI and mini display on top, and 1 DVI at the bottom. Screens were connected middle top DVI and bottom DVI(same gpu called gpu "a" in Nvidia panel )).So now I have 1 screen connected to DVI-D(middle top) - same thing happens. I then disabled Multi GPU, restarted. I tried each port while SLI is disabled and found out that I do not get artifacts only when I have 1 screen connected to the left upper DVI port port on my card, it happens to be second GPU port(GPU "B" in Nvidia control panel). So I am unable to run multi GPU or 2 screens at a time, because the other 2 DVI ports seem do not work properly, hence my GPU "A" is bad?
 
Any thought on this? 

Solder cracking somewhere on the PCB has probably occurred and is causing the problem..Not uncommon for those cards and other cards of that era.

Completely disassemble the thing and bake the PCB (aka 'the oven trick') like this which should reflow any solder cracking, and hope for the best.

If you bake it, do it with the GPUs side up..200C for 10 minutes.

Good luck.

I got no other oven 

Guess you'll have to make a decision to either purchase a cheap toaster oven to attempt to repair your card, or just put the funds that you would be spending on the cheap toaster over towards a new card.
