I'm running Windows 7 64-bit and recently my monitor (Samsung SyncMaster SA300 LED) has begun acting up. At random times my screen will turn completely black (the monitor remains powered on) and when it returns it's like the resolution reset (ie: the mouse cursor is in the center of the screen and all windows are bordered) and the device "disconnect" sound plays through the speakers. More recently, while playing a game, the screen will turn black and when it comes back, the screen resolution is skewed, often times extremely zoomed in.

I've attempted updating the graphics driver, installing Windows updates, virus scans, etc and nothing appears to be helping. This appears to be happening at completely random times, while browsing the internet, checking e-mail, playing games, etc.

Any help that can be offered would be greatly appreciated.
 
try the monitor on another pc see if the monitor is the issue or the pc. most times video issues like yours is a power supply that not holding or a failing gpu. look at the power supply voltages inside the bios if the bios has voltage reading. see if the 12v line drops at all. if not use a 3 party software to watch and record your system hardware.

This happened to a friend of mines with a 2 grand computer it always gave him a black screen at random times from browsing the web or playing games or during idle. He had a samsung too and it lasted him 4 years and when the issues happened it died out on him in 7 months it wouldn't turn on. Since monitors have their own power source its kind of hard to tell unless you have a meter or get lucky to see any defects inside the monitor for swollen caps, burns, or burnt cables and pcb.

Do what smorizio suggests or revert back to an older version of drivers if your using the latest drivers and see if that's the cause. But if you have any spare parts it would be easier to troubleshoot use another card or monitor. And make sure the refresh rate on your desktop and games match with your monitor specifications.

Other thing to do is never download drivers for your hardware on windows update because that always locked up my computer or gave me blue screens. I always download directly from the vendor unless they don't support it anymore 4 years tops from last update. Because once you download every update and start getting problems it will be hard to trace the problem lol.
