Ok here's the system,
Monitor: Dual Monitor with Acer GD235hz (that's their 120hz 3d model) as main.
Graphics: EVGA Nvidia Geforce GTX 260 (most up to date drivers at the time)
Processor: AMD Phenom II X4 810
OS: Win 7 Home 64 bit.
Ok i'm sorry if this has already been answered but it's a bit complicated so hard to search for. Here's what happens, i'll be playing a game (this mostly happens durring FPS's, of which i've been playing Bad Company 2 the most), then all the sudden when i click the screen will go black as if i just Alt Tabbed (but obviously i did not) then immediately reloads, then runs fine, also I know this has nothing to do with it but it seems to only happen right when i'm going to kill somebody. Also to be noted is that this has started happening only since i got my new Acer monitor.
Can anybody help me out to figure out what causes this and to get it to stop.
