I am custom building a computer. My problem is, when I plug my monitor into the vga port the screen goes blank and the power light starts flashing. I have checked the motherboard with other devices to see if they get power and they all work (harddrive, floppy drive & dvd drive). The cmos is set in the normal position.

Re: no power to monitor
Is the Bios rom set to the on board settings for the video driver?? Did you allocate enough ram for your video driver in the Bios rom?? If all thats ok then the on board video driver is bad or not configured properly. Try disableling the On board video driver and stick a video driver card in and try and see if the monitors working correctly. Good Luck

First steps are always to check your connections. Is the cable to your monitor secure at both ends? If it is, are there two VGA outlets on the back of the computer and is your monitor connected to the correct one, ie Integrated with the motherboard or a separate graphics card. If you do have two VGA ports on the computer, try the other one.
Two other relatively easy tests are:
Firstly plug the monitor into the VGA port on a laptop and using the relevant Fn +Fx key for swapping, see if this will give you a result on the monitor.
Secondly try plugging another monitor that is known to work into the computer and see if this gives you a picture on the monitor.
If the first of these gives you a picture then it is likely that the graphics card, (or graphics component on the motherboard) has given up the ghost, and the second test yielding a blank screen will confirm this.
If on the other hand the first does not give you a picture and the second does, this confirms that the monitor is faulty.
Hope this is helpful, if so would you please register that with Fixya
Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
i fixed this problem by unplugging the monitor, unplugging the video cables. Then hold down the power button while plugging it back in. Release power button and then press power button for on. It worked then. I got the icon for no signal, i plugged back in my monitors. Sceptre X9W
