I have a really weird problem with a computer and a monitor: One day I was on the computer and all of a sudden screen goes black, I get check input/signal. I do all the normal stuff- reseat VGA card, make sure cord is secure (I even bought a new cord), I reset CMOS memory- all to no avail. I then plug the computer into another monitor and it works. "Okay, it's the monitor then" I think. I plug that monitor into another computer and I get the same error; this of course backs up my thinking. Then however I plugged the computer (Which I had just found to be working fine) into a brand new monitor and I get the same error...Anyone ever experience anything like this?
