Click on "Power Supply Light is On or Flashes"
I solved my problem with Compaq SR2020NX not power ing up by "resetting" the voltage selector switch. (Found on link above).
Check your connections to the monitor and pc make sure all your connections are secure. It could be a bad video card in the pc, bad cable or bad monitor.
your monitor is not recieving a video signal from your pc. check your connection to pc, then check things like bad memory card, etc. sometimes just shut pc on and off a few times clears this up.

Hi hay783...
Sounds like you may have a virus/trojan/worm/etc...
--------------------------------------------------------------------------------------------------------------------------------------------
To remove a virus,trojan,worm,etc from your computer...do it the EASY way...let someone else do it for you.
Start your computer, as the computer is starting keep tapping the F8 Key.
This will start the computer in the Safe Mode.
Once in the safe mode go to the following webage below and download,install, and run Microsoft Safety Scanner for FREE.
Once you run the Microsoft Safety Scanner (it may take quite a while depending on the size of your hard drive) it will remove all the virus's,trojans,worms,etc it finds, if it does not completely remove them all you will be given a chance to chat with a Microsoft Professional thru a pop open window and he will take control of your computer (with your permission) and finish removing all the rest of the virus's, trojans, or worms that are on your computer for FREE!! Can't beat FREE!!
