the make (Acer, Gateway, Dell, etc.) and the model and model number and the Operating System.

Also and very important you need to let us know if it EVER sent any signal to the monitor and if it did what happened immediately prior to not being able to see anything on the screen any longer.

Provide more details....


Next, it'll be better to swap monitor to another PC and see if it works. If it does then you know your PC is at fault. What else does your PC do when power is applied(remove side cover)? In many cases, it has been shown that replacing the PSU is a good idea even if not the cause because it rules it out as well.

My father had this exact thing happen a couple months ago. It started out having problems coming out of sleep/hibernate mode. Then after a while nothing showed up on the monitor at all, even though the PC was on and running. Luckily I happened to have an extra brand new monitor laying around, so I gave it to him and hooked it up to his PC. This solved the problem. Once the new monitor was hooked up, no more problems whatsoever. So either his power cord was bad or the monitor itself went bad.

If you have another PC or laptop around, try hooking up your monitor and see if it works. If not, then something is probably wrong with the monitor. Or if you know someone with another monitor, try hooking one up to your PC and see if it works. Again, if it does work, then your monitor has a problem.

you don't tell about, this can be an issue of:
- monitor
- cable
- videocard
- motherboard and components
- power supply

If you say it isn't cable, monitor, video card, it's motherboard (or the RAM, or the CPU) or the power supply. May be time to find a repair shop.
