I recently bought a Nvidia GTx 560, It works fine for about 5 minutes into the game and then my monitor (LG Flatron E2250v) Goes blank and says no signal ?

Could be your PSU can't cope or is failing or the card itself is faulty. Contact the supplier and state what is happening.

Overheating is a possible problem too. Try running a stress test both (both a GPU one, such as Furmark, and a CPU one, such as Prime95), and see what temperatues you're getting. You'll be able to monitor your GPU temperature using the nVidia Control Panel, and your CPU temperature using RealTemp
