After reinstalling windows, changing power supply, changing ram, changing video card, optical drives, then trying a new harddrive I have finally found out why Gameex randomly locks off and my screen goes in standby mode. Nod32! I've loved nod32 for the past years I've been using it, but I think the active monitor is choking it up because it tries to scan each file thats accessed, and when skimming through my romlist I believe its a bit too much overhead for it. Beware fellow users, it's had me down and pulling my hair (and pc components) out like made for 3 weeks.
