There is an electrical problem with either the power cord connected to the monitor or the outlet that it is plugged into.

If its a brand new monitor, return it to the place of purchase and exchange it.

If its a used monitor then I would suspect that someone has given you the wrong power cord for the unit. Sometimes people check to see which cord "fits" the unit and think that its appropriate because they can connect it.

That is not correct when it comes to monitors. Just because a power cord fits by connecting to the monitor does not always mean its appropriate to run it correctly.

Check the voltage requirements on back of the monitor and compare them to the power cord your using with it. If they are appropriate and your still experiencing this problem then the power cord might be bad.

Test this possibility by disconnecting the monitor from the computer and turn it on. Do you see a screen that says "no video" or "no connection"? Does the screen blink the same way as when connected to the pc? If it does, then its the power cord or supply source its connected to. Plug it into another socket and and see if you get the same thing and that tells you its the cord.

If the display is good when not connected to your pc, then use a process of elimination to figure out if its the monitor cords connector that is broken or frayed or if its the video card connection that is either loose and needs to be re seated in your case or the connection itself is unsturdy and needs the bolts tightened to give a solid connection.

How do you do that?

Check the pins on the end of the cable that connects the monitor to your pc. Are any broken, missing or bent?. Check the other end that connects to the monitor and verify the same thing.

Then try and jiggle the video card by grabbing the area that you connect the monitor cable to on the back of your pc's case and see if it is loose. If it is, get a screwdriver and tighten the screws until its tight.

Try plugging it in again and see if this solves your problems. If it doesn't then clarify your findings and I will help you solve this issue another way.

Hi,
Please check if all the cables are properly plugged in. If yes, then remove the vga cable with the blue plug from the back of the monitor, make sure that you do not remove the power cable. if you see monitor self test or any colors on the screen it means that the monitor is fine. but, if there is no display still you need to change your monitor.
then the problem is in the tower, please check the power supply if it is working or not. If yes, the problem is either with the mother board or the memory.

Thanks and Regards
Anand Sachan

Sounds like a corrupt install.
