Ok, First remove the memory you install in. Then take of cmos battery for a couple of minutes. Then replace it.memory too. Make sure you do not power cable on for computer.
Listen this: turn off monitor. turn off desktop and remove all power cables from outlet. First connected monitor cable to computer then plug it to outlet. then connected desktop and turn on. when computer powers on press and hold F8 see if you can see safe mode. Then as me again.

Which power button is flickering (your computer, or your monitor).
Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
First, check your video cable. It should be securely connected to the computer (and monitor if not built in). If you can, try a new cable. Try the monitor on a different computer and the computer with a monitor that works on another computer. (This tests if the monitor or the video output is the issue.) Once you figure out where the failure is, you can decide whether to repair or replace the monitor, or deal with the video card.
I hope this helps.
Cindy Wells (we had a monitor that went pink due to a loose vga cable. once we looked at the cable instead of the computer or monitor adjust buttons, the fix was easy.)
Press F8 while booting and select Safe Mode to see if you can get video. If you do it could be a driver problem and you could uninstall the Display Driver in Device Manager and try to boot normally and look for an updated driver. Reboot into Safe Mode again and select Cancel if prompted to install drivers when restarting to avoid reinstalling the existing drivers if it fails to operate after doing so. If still having issues it could be a failing video card or motherboard if the video is integrated.
There are a couple of things it could be. From simply checking the cable on both ends (computer to monitor) to see if they are loose. It could also be the card is damaged. I would check it with a second monitor to be sure.
This could be one of three components: 1. The video card 2. Video Cable (cable from the monitor to the computer) 3. The Monitor
The way I would determine this is:
I would try to plug this monitor into another computer that you know works with other monitor. If this is a home computer and you don't have another computer to test this take it to a friends house. Use a different cable to connect the to computer and power if possible. Then switch out to the old hardware (e.g. power cable, video cable.) If all has been determined to work then it's probably the video card.
If you can do this at all I would suggest trying a new video cable they are cheap. Usually 10 bucks at the most or borrow on from someone else. If this is a DVI cable they are a little more expensive. VGA cables look like this btw http://www.networktechinc.com/cable-pc.html
