Ran fine booted up and everything then 5 min into play starcraft BLACKNESS followed buy horrible omg fan noise. took for ever to get it to reboot and my computers surge warning came up -.- I am running a 850 watt power supply which is way more than i need i upgraded to that just for the card. Once i got it back tried reinstalling drivers ran fine for 10 min the BLACK again ugh........changed voltages added/ took away fans. Tried again......BLACKNESS this time i open the case right up and OUCH HOT the card was on fire after about 5 min........Help what do i do? I returned the card for a new one but i am afraid to have the same dang problem.
