Recently, I've started having intermittent problems with my monitor
during boot-up of the pc. It is not a consistent, reproducible problem.

The problem - after powering on my pc, the monitor power LED light
flashes off/on but the screen ramains blank. Nothing is displayed.

Usually, I get frustrated and power off and then back on my pc, at wich
time the monitor works as expected. The one time where I was patient
enough to see what would happen, it took about 10+ minumtes before the
monitor finally started displaying an image.

This is the only pc and monitor in my home, so I do not have any spare
monitors to swap out the monitor to test if the problem is with the
monitor or with the mobo.

System
Monitor: HYUNDAI ImageQuest B90A
Mobo: ASUS M4A89GTD-PRO/USB3
CPU: AMD Athlon(tm) II X3 440 Processor
RAM: 4Gb
braphics: ATI Radeon HD 4290 - integrated chip on the mobo


So is my boot up problme wrt the monitor due to a failing monitor or to
the motherboard?

If the problem is wrt the motherboard, will adding a video card to
resolve my problem?

Thanks,

John

Look for bulged capacitors, near the video card slot in the pc.

Checked but did not see anything out of place.

Take your monitor to a place where there is another computer you can hook it
up. Make sure the monitor has not been on for at least two or three hours.

The symptoms you're describing do have a ring of failing caps, but they are
not necessarily in the mb but could be in the monitor itself or the power
supply..

The alternative is to bring in another monitor and hook it up to your
computer.

I had nearly identical symptoms with my Samsung 940mw monitor. It was
bad capacitors in the monitor. Open the monitor and look for bulging
caps particularly on the power supply or inverter boards. Even if they
aren't bulging they could still be bad. If you can solder it is a cheap
and easy fix.
