Does the monitor work with another computer? Maybe a laptop? Try this first.
Your problem could
be the result of overheated capacitors on the Display card, or maybe heat build-up inside the computer case resulting in that.
The same thing happened to my son's computer, and I thought he had it on for too long playing games. I opened it up one day to find that a couple of large capacitors on the AGP display card(little things in black or grey plastic shrink-tubing, about the size of your first segment of the little finger) were leaking some fluid!
To cut a long story short I replaced the 128Meg board temporarily with an older 64Meg model lying about and the problem went away....
That is, until I put the original board back, (me having replaced all eight of the 'caps one by one). Now it sort of blacks out once in a long while and comes right back again...in 15 or so seconds... He needs a new computer anyway , so I'll leave that, haha.
I'm convinced my problem was the lousy display card, a Winfast A170...
They make better ones this day, with Polyester 'caps instead. No fluid inside anymore.
Try replacing the display card first. It's cheaper than buying a new Monitor.
Hope this helps.
