My monitor won't turn on. Everything is connected properly. I press the "on" button and get no response at all. What could this be? Could a virus do this? It's a Dell flatscreen and is only about 4 years old. The computer still turns on. I'm sorry I can't give more info about my exact OS or CPU--no monitor!

Was the power on the computer, when you plugged it in? :p HaS it been a cold night? :p Does your computer smell like fireworks? :p --------------------
Thor Byrgesen: The one,
oh the one computers and all electronics just hate.
"The computer still turns on." Do you get the initial single beep when you power up the PC? If not, that means your PC is dead.
OR-A faulty cpu fan will do that to protect the cpu from heat.
Does the power button show orange or green? Life's more painless for the brainless.
We need the make & model details of the Dell Flat Panel. BTW, did the monitor pass a self-test? It very well could be culprit - even though it's "only" four years old :-(
Thanks for your responses. Thankfully, no fireworks yet! =) When I turn on the computer it's a green light--I haven't paid attention to whether I get a single beep or not, I'll try that when I get home. What do I do about a faulty cpu fan? And how does one do a self-test?
On displays that feature a self-test routine, this is usually accomplished by simply disconnecting the VGA or DVI plug from the monitor while leaving the display's power cord plugged in. If you see an image: the monitor is not the non-display issue's culprit.
I'm having the same problem with my comp - I removed the CPU fan and heatsink to clean them, and I think I may have replaced them improperly, because I've tried two other graphics cards, and the monitor still doesn't respond, and there's nothing wrong with the monitor connectors, as I've hooked it into my laptop and it works just fine. My PC does turn on, but it doesn't give off an initial single beep. I've checked and the VGA card, PSU, and CPU fans are all working. Think I need to replace the processor?
