While playing a games with my new system the screen freezes, turns grey, loses input signal, then comes back on(while playing in window mode it says that the drivers stopped responding and has recovered). I believe it is the graphics card because it does not do this with the on-board graphics card but xfx says it could be the memory or the ram voltages could be off(they are set to auto).
I have disabled the on-board graphics when using the card.
What do you guys think? Thanks in advance.
