Can't figure this out. A few hours after running a Playstation emulator (EPSXE), I started getting issues where my screen would turn off for a half-second, then on again. It started off infrequently then happened more often. Whenever it does this, I noticed that the game advances frames more during the "black screen" time than it normally would with the settings I have. The game is in window-mode, but the whole TV screen turns off when it happens. My output is currently set to HDMI, with the same cable carrying sound.
I have heard that it could be all sorts of things - bad card, voltage issues with the power supply or motherboard power-saving features, drivers (which I have updated - still waiting to see if that helps), overheated card... Any advice / ways to keep it from happening again?

So the display and sound drops off for one-half second. And it is because hdmi cable is set to transmit both sound and picture.
In my opinion, the game continues playing in the computer but the hdmi cable momentarily cuts out. So you cannot see and hear anything. The TV set does not turn off.
Can you reseat hdmi cable at both ends (computer and TV set) and/or try another hdmi cable ? Broken wires in the cable or loose fit might cause this because sound waves may cause shaking of the cable during high levels causing cable to lose momentary connectivity.
