I will try to make this as short as possible.
I bought a new flat screen monitor (Samsung) for my Dell desktop. When I hooked it, the computer comes on and starts to hum along, but the LED light on the monitor starts to flash. Called Samsung and they told me to try a different monitor. So I hooked my old Dell CRT monitor. It doesn't work either. I am baffled. I haven't used that computer since I left school and I just unpacked it the other day when I hooked up the monitor. This computer is barely a year old (but just old enough for the warranty to expire. grr.). I'm thinking that maybe this is a video card issue. A friend of mine installed a new video card (Radeon something)in it this spring and it worked fine. I'm going back to school in a week and I need this piece of junk to work!
Any help would be appreciated beyond the point of decency!
