My monitor will not turn on

By sueboring ·
Although i have changed the graphics card several times, the monitor will not switch on, i have checked the motherboard manuals, bus speed of ram and cpu, i have used the AGP slot and PCI slots and none will turn the monitor on. the base unit starts up fine, the lights flash the hard drive humms but no screen, is it a faulty motherboard or have i missed something?

Does the MB have onboard video? Try plugging the monotor to that. If it works there then you will have to disable the onboard video (integrated peripherals in BIOS) to use the video card.

First question
does the monitor light up at all ?.
does it go orange but not change to green ?
If no lights try another monitor.
I recently (last 2 days) had a similar problem.
Monitor light would not change to green.
everything seemed to be ok
It was the main processor, changed it everything ok.

Clear the CMOS settings by shorting pins 2&3. They are usually located near the MB battery. Also remove the battery for a few seconds and then replace the jumper on pins 1&2. This will restore the factory defaults. This may clear up the issue. If it does, you'll be able to go into the BIOS and change them to your liking.
