Monitor not working after POST

monitor problem.

if i turn the computer on, the POST screen comes up and it displays as it should, however once past that the monitor stops working - eg, goes blank.

i'm trying to install windows xp from a cd - the cd fires up and things seem to be happenign bu the screen is blank!

already installed in suse linux and if i don't try and install xp the same happens, i can see the POST details on the screen, then a screen comes up asking if i want to start suse, if i ok this, then again things seem to be happening in the background but the monitor goes blank!

any ideas at all? even some thoughts/clues as to what i should even be searching google for would be very handy.

I'm guessing that you're using an analog monitor connection...

It sounds like a fault in the multi-sync circuitry of the monitor but it might be a fault in the graphics card so you'll probably need to do a temporary swap of the monitor to be sure.

Assuming it's the monitor, it's not user-fixable, a new circuit board will probably be needed.

It is possible (but unlikely) that the monitor is simply unable to switch from one frequency to another. In this case, switching off and on again each time the frequency changes may work as a temporary fix. I have seen this work on an old Taxan LCD monitor.

If monitor and graphics card both have digital connections, then try using them.

yes, on board graphics are analog.

i've switched monitors, i get the same problem with each monitor- which all work fine on different computers.

i've added another graphics card - analog only connection - and the same problem, i'll see if i have one somewhere with a digital connection.

thanks for the suggestion! i've run into a dead end searching online, hopefully a digital input will resolve it, if not i'll take it to a computer repair place if i can find one!

It could be a bios issue, check onboard graphic options.

The bios video settings probably have the size too big or refresh rate to high.

Test the monitor on a good system, if good then reset bios defaults. If that fixes it then you can tweak your bios settings as needed.

There is a chance that you already have a config file set for monitor settings such as a previous installation or another os.

You know you've done too much web development...

...when your first reaction to the post title is to wonder why on Earth anybody would think a type of HTTP request could break their monitor!

That was my first thought too! :)

Yeah, I had to think a second on that one. ;)

Try a Linux install disk. If the same thing happens, you've got a hardware issue.
