what to do?

ok so i have read through about 20 pages of this forum and im still not sure what to do, while playing games like arma 2 or call of duty 4 my video card, i belive, is shuting down and i get a no signal on my screen, then have to restart computer. i have a gts 250 right now and i dont know if i should get 2 and sli or get a better video card, if that is the porblem. doesnt seem like its overeheating, when i touch the card it is barley warm

pc specs are
650w power supply with 1 52a 12v rail
intel quad core 9550
4gb ram 800mhz ddr2
gigabyte ud3p 45? mother board
bfg gts 250 oc

Still could be a defective card, how long have you had the card?

i bought it about a month ago, it seems like it only crashes when its got to work hard

What mobo have you got??
GA-EP45-UD3P?? It don't support SLi anyway.

What happen to your card? is it faulty?? Do your PSU juicy enough to run the card?

I would stiil install something like EVGA Percision and make sure what the fan speed is and the Temp.

could be PSU, could be bunk GPU. It sounds like you think the card is just not powerful enough: this is not the case. It sounds like a hardware problem but it never hurts to update drivers.

edit: forgot to give advice... RMA RMA RMA (chanting), if you are running up against an RMA deadline then get that sucker out the door.

ok so i got evga precision and the fan speed was at 38 and gpu was runing at 50 so i bumped fan speed to 60 and got 42 under gaming and it still crashed, so i returned card and got gtx 260 for 20 dollars more hopefully it works, still downloading drivers. oh yea this is the second power supply i have tired first one was 650 with three 12v rails at 22 amps and still had the same problem

*update* new gtx 260 works great can play through a whole mission on call of duty 4 single player
