My acer starting doing this over a week ago. I turn the computer on and all is good. After 5mins or so the screen goings blank like I turned off the monitor. If I turn off the monitor and then turn it back on the screen comes back; sometimes for a 10 mins sometimes for 10 seconds and it is getting worse. I changed out the video card, monitor, and monitor cord but it didn't help. This acer is a desktop and I bought it new a couple of year ago.
ANY suggestions would be appreciated.
