I have a q8200, radeon 5850 (xfx black) and 8g ram. Monitors (exended display) benq GL2440HM (max 1920) and Acer mw221u
My problem is that when I start up my computer the displays work fine, I can play LOL at 1920 on the benq and have videos (vlc/embedded firefox HD streams/tv tuner) running on the Acer. When I alt tab out of the game, the time is about 1 second to return to the desktop.
However, it seems that after I've had the computer on for hours using the monitors in this way, the lag between hitting alt tab and the desktop coming up gets as much as 10 seconds, with both screens turning black and even some audio stuttering.
Restarting the computer fixes the problem but it's reallly annoying having to do it all the time. Any thoughts on what it could be or how I could solve it? It's almost like the graphics drivers (I'm using latest but it happened before too) are giving up the ghost or the memory on the card isn't clearing properly... I dunno I'm a noob but help would be appreciated.
