Graphic card working after removing dust

i would check your power supply make sure that it can handel the load of your new card and that the 12v leg has the current rating for the card. i would then run memtest just to rule out your ram. you can also run prime95 to check your cpu..there also gpu burn in programs that you can see if the gpu artafatcs in burn in. i would also download msi afterburner to see what the default fan speed is set and is the fan ramping to keep the card cool.

which motherboard are you using?
