My Monitor goes black

[adast]

Okey.... so i had this pc for few months now maby like 4-5 months something and yesterday i was playing dead island with my friend and what happen my monitor went black But... i can hear the game sound its like monitor has been disconnected from GPU i turned my monitor off and on still nothing then after few second this nasty smell came from my desktop that smell was like something was burned so i quick turned off my pc and turn back again.
what i notice that i cannot play games when i start playing my monitor goes black but i can at least play MINECRAFT :d and watch movies browse internet so i been thinking maby its GPU because it says disconnected from my pc

Try using another video cable. Could be that the cable has a bad pin or something.

it cannot be cable because that cable is brand new and i think its graphic card because that stinky smell came from it i think

What i did now i play the game in windowed mode and it works but if its fullscreen it just goes black what problem can that be graphic card?

Try to uninstall/reinstall the driver. IF not, then get that card RMAd
