Monitor not working Wait??

After I received help with an old modem and setting the IRQ and and com values, I got another problem. I found other similar threads in this category, so I put it here.

When I took the printer (not working correctly) and the modem out from the system values, when I rebooted, the monitor had no response. It sounded as if it was following the steps it had before, but the monitor had no response. I tried it on another computer and the monitor was OK. And when I tried another good monitor it did not work.

I tried removing other cards- the monitor hookup is part of the motherboard-with no luck.

As I was looking through other threads dealing with the same thing, I tried powering it up again, and it worked OK.

Is there anything I can try that might point to the problem?

Thanks for all your help

 

And now it is doing the same thing as before.

I was changing the resolution -as it was in safe mode- and followed instructions to reboot.

But it never did. When I cold booted, no monitor response.

Thanks for any help

 

It sounds like you may have to reinstall the driver for the onboard video. Also I would check their website for any updates while your at it.

 

Make sure that if you have seated the Vid Card fully. Also if you are not getting a POST it may mean that you are having Power Supply issue. Can you hear the HDD spin up? does your CDrom and Floppy lights Blink?

 

To quote some great literature, it's getting curioser and curioser.

Turns out that if I unplug the the keyboard , the screen will come on. then if I plug the keyboard back in, everything is OK.

Guess it would be a good idea to find a replacement keyboard to check that out.

Thanks for all your help

 

Should drop back 15 yards...

If I unplug the keyboard, the second time it boots (most of the time the monitor has no response ) the monitor will come on. If I plug the keyboard in, it works OK.

Changed keyboards, does the same thing.

I have an NEC 9725. Have not been able to find any website for any drive or update. Anyone know if one exists for NEC?

Thanks for all your help.

 

I think your onboard video is the S3 Virge DX. Try the site below and look at the Drivers section.

..http://www.s3graphics.com/index.html

 

I tried the site for S3graphics, but got no meaningful information when following the instructions.

Have taken all additions out of computer. If I select the restart option, it will do so OK.

But most of the time. when it starts up and there is no response to the monitor, I can unplug the keyboard, turn the power off and on, the monitor works. I plug the keyboard back in and it is as usual.

I know that I am dealing with symptoms, but if anyone recognizes this, thanks for your help.

 

Howdy there elmer...

What I would try is to reseat the memory or change the memory, because it looks like you have on board video, and in most cases it shares the main memory...

The reason I say this is that I have a bad stick of memory, and every time I do a cold boot I have to reset the pc ( I also have on board video that shares the memory ), in order for the video to work, and get to the OS...

 

But you two cents might be anothers pot of gold

that narrows it down to 4 sticks to check. which brings up another question, Does anything exist to check memory?

The quote statement. Is that just to point out something that was stated before?

Thanks for all your help

 

What I would try is a process of elimination, remove all sticks of memory, then start adding them one at a time untill the problem reoccurs...

And...there are several software and hardware tools to test the memory ( most of them cost mega $$$ )...

I've used this one in the past, it takes a while to test each memory module ( I would try testing them one at a time ), and it proved correct results...

And...yes the quote was just to point out an observation that you sated before

 

Mr. Master

I obtained the memtest86 information. Ran it a few hours and have received no errors.

If it found no errors, should the elimination process still be followed with the Memory sticks? Or should the test have come up with something?

think I'll be on the lookout for good deals on new computers!

Thanks for all your help

 

When the computer starts up with no video, there are two short beeps at power up. Normal I think it is one beep.

Usually, unplugging the keyboard will allow normal power up. A while ago, when I unplugged the mouse, it allowed normal power up. And if I took out a modem that I installed, it would allow normal power up.


No doubt I am dealing with symptoms, but . .

I was reading I believe in this forum the procedures to follow to check temperature. I don't think this is a cause, but you never know. I tried a search with no luck. Maybe someone knows, or can lead me to the thread

Thanks for your help and any suggestions

 

Do you know what bios is in the computer? If it is AMI the 2 beeps mean a memory problem. Look on the first screen when booting in the lower left corner it may tell what it is. If not try downloading Belarc from the link below and see if it tells you what bios you have.

Phoenix Bios ATI-264gt/a2b EDO Bios 2.224

version 4.05.m

NEC 00.01.27

That's probably more than is necessary, but that is what I hae written down.

Thanks
