Monitor flashes when PC is powered off

By ajhunter ·
I currently built a PC for my daugther's birthday. It has a Gigabyte GA-7VAX M/B with a AMD Athalon XP 1800+ processor. When I power off the system, it goes through it's process and shuts down properly. However, after it shuts down, the monitor powers off and then attempts to power on repeatedly. The only way to stop the process is to shut the monitor off manually. Can you give me an idea what potentially may be causing this problem? Thanks

When the system is shutdown, it's normal behaviour for the monitor to flash the power-led on the monitor. This tells you that there is no signal on the VGA port/cable.

If this is not the case , please give us more information on how your monitoris connected to your system (the power connector)

The monitor is trying to "wake up".
This falase signal for this can be a bent pin in the monitor connection to the video card, the pin can be pushed back into the shell of the connector thus shorting out.
The problem can also be in the video card.
Since you just built this PC, the high dust buildup problem is not in consideration.
I am also assuming there is not a conflict in the BIOS setting, and that "power off button causes sleep mode" is not set.
This is going to require some troubleshooting because of the many possibilities.

Need a little more info. What type of video card are you using or is it onboard video? Most new motherboards (ATX) have various power settings when shutting down. Although the system has shut down, the power to the motherboard is still active (ie. modems and NIC's are still powered and active). Check your BIOS for WAKE ON LAN settings. Easy check would be to unplug the computer and see how monitor reacts. It sounds like your monitor is getting a faulse signal from the video card.

Unplug the computer and see if the monitor still trys to power-on. A flashing power light is normal and does not indicate it is trying to power-on only awaiting a signal from the video card. If your monitor came with a user manual, see if it has error code (flashing light sequence) to determine monitor problems.

Is the monitor plugged into the same power strip as the PC? Are they plugged into a UPS? Just something to think about, the other suggestions are probably closer to reality.

How old is this monitor? If its older it may not go to sleep right away and will complain that "Video Signal is not Present"...it should go away after a few minutes. If its really old it might not ever go away.

An amber flashing power light canbe ignored on the monitor...if you are seeing a graphc on the screen then something is wrong and I'd look for bent pins on the monitor cable.

Basically though, why not just shut off the monitor when you're done with the computer? I know its not much I see no need to waste power.
