Do you remember making any changes to the computer recently?
This seems to be a connection problem or the cable is gone bad.
I would suggest that you connect the monitor to another CPU unit if you have this is to check if the monitor itself is gone bad. Also make sure that the connection to the monitor is correct. Also try connecting another monitor to the computer and check. This issue may also occur if the signal from the video adapter exceeds the scan range of the monitor. The video adapter setting for updating the screen (the refresh rate) is incompatible with the monitor.
The maximum resolution for the MV540 is 1024X768 @60Hz refresh. The other monitor isn't giving you an error message because not all monitors have that feature, but both the monitors are unable to display whatever data the computer is sending. If the display is normal until you start the game, then the game itself is setting the resolution to something out of the monitors' range. You'd need to set the game up to play at a setting the monitors could handle. I've never played WoW so I have no idea if the game offers a way of selecting the resolution. The game may simply require more graphics capability than your monitor can provide. Most systems now are using 17 or 19-inch flat screens or CRT's, and they offer more resolution and refresh rate options.
Reinstall the game the resolution for the game maybe out of range for the monitor, this will set the resolution back to defualt. does the monitor say "out of range or out of frequency" when the screen goes blank? if so it is the monitor being incompatible with the current resolution setting. if you changed monitors recently this may be why. Otherwise it is not compatible with your existing graphics card
some games need high resolution. Monitor resolution not supporting for this game.

Most commonly, this problem is caused by an incorrect refresh rate setting. LCD monitors typically DO NOT support refresh rates higher than 60hz - and this is no exception. Try running the game in "safe mode" if it has one. Adjusting the in-game video settings should solve the problem, just look for a screen refresh rate or any video-related setting with a number followed by "hz". Set it to 60, everything should be fine.
It could also be that at some point the game changes resolution (this frequently occurs if there is an in-game movie or cut-scene). In this case the resolution settings for the in-game movie might be at fault, check them if you can.
