My PC is starting but the monitor is not starting meaning the light of my monitor is blinking on and off and there is no display. So what should i do? Motherboard version=P5GL-MX.

Hi.

If the Power Light blinks, its means that the monitor is in ' STAND BY Mode '.
Monitor stays in Stand-by mode only if it does not getting any signals from computer.
please check the cable which connects the monitor and computer are connected properly.
Also check that the cable is connected to the proper slot of the computer.

If you hear some continuous beeps when you start the computer, then the problem may with the display card ( Video Adapter or Graphics card ) on the PC.

thank you

"no signal" means exactly that. You monitor is not receiving signal from your PC. Recheck the video cable on both the monitor and the PC, make sure they plugged in properly.. Also try another monitor if you have it, and if it works with that monitor than more likely you have a frequency sync problem. In this case, using another monitor that works, and try resetting the video to basic 60Hz. In Windows, Start->Control_Panel->Display. Change the display resolution to the lowest, apply the setting, then change the monitor back to the questionable one. If it still doesn't work, then your video processor on your monitor is bad; RMA it if it's still warrantied.

Blinking picture problem, try suggestion above.

A blinking power light typically means there is no signal from the video card, so check the connections and try another monitor (or plug the monitor into another computer) first to see if the video card is perhaps the real culprit.

first check your monitor front power light blinking or not.
if it's blinking then then remove the signal cable to the cpu then check the company logo moving in the monitor.if it's moving means your monitor is OK.means no display in *********** board.

make sure that all the cables are connected FULLY.
blinking light means that there is no signal.

The monitor requires service The monitor is not receiving a signal from the computer

do u mean that the monitor is dark, and LED on monitor is blinking?
IF yes, then probably display problem...
If using graphic card, just switch to built in display...
If this cannot, u can try clear CMOS...

1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )

This works if you boot the monitor with a pc, open the osd menu and go to reset. reset the monitor.

One of 2 possibilities come to mind. 

 

1,  The vga chord is loose on the back of the monitor.

2, Your resolution is set too high or low to be displayed.

 

The blinking light means that the monitor is either not getting or understanding a signal.

 

Hope this helps.
