Monitor not recognized.

[Keith777]

Hi my computer is not recognizing my monitor in normal windows mode, even though it sends a signal and displays fine during start up , and in safe mode. I had to go to a net cafe to send this sad plea for help. Here's what happend...

I turned on my computer without my monitor pluged in, its not USB, its one of those blue plugs with the two screw things on the side and square with pins inside. The top side of the square is wider than the other. You know that one.
(ACER AL1913)

So I pluged it in after it had loaded up, (maybe during, not sure) and nothing happend, there was nothing on the screen like I wasn' t receiving a signal. Just black.

I rebooted and the screen was showing the usual boot up stuff, so i know it's connected properley and all that, so i thought it was working but just after the windows splash page, when the "log in window" usually pops up, it goes black, I briefly get my monitors firmare "no signal" message. Also the green light next to the monitors power button goes orange, wich it usually only does when the monitor's turned on before the PC is turned on.

I rebooted serveral times with the same effect. I had to reboot into safe mode just to be able to shut the PC down from its start menue. So in Safe mode the screen shows up as it usualy does in this mode.

I did a few things to try and fix it wich may not have helped....

I removed all the monitor entries from the device manager hoping it would have to re-recognize it and then re-install the drivers for it. I got all the exact same symptoms trying to boot into normal windows. It also didn't re-load monitor drivers going into safe mode. It's wierd. I have no montior listed in my device manager now but the symptoms aren't worse than they were before.

I also merged a copy of the registry i had from earlier in the year and it made no difference.

I've never gotten my "safe mode with network support" to actuall connect to my DSL so i've had to go to an internet cafe to post this. I will be back tommorow or the day after to get any feedback, if any. Feel free to dump multiple things to try at once or in order as it will save runing back and forth (i've recently recovered from a sprained ankle).

Thank you very much for your time.

Keith.

i would do a check on the graphic card, is the fan spinning normal, try 2 reinstall the drivers

I agree it sounds like a video card issue, is there one or are graphics onboard? You may have damaged the card or circuit by plugging in 'hot'. Please post back the graphics hardware.

Look for an updated chipset driver set from VIA website, might help.

Best of luck!

Sounds more like a driver issue to me. Since it works fine on pre-load messages, that says to me that the video card is OK. Only after loading Windows does it fail. Again, that points to a driver issue. Have you checked CMOS to for any changes there? If it's a plug in card, try removing it and re-inserting it. If it's an integrated card, make sure CMOS is set to use it. I don't think you could have blown the adapter simply by plugging in the cable. Shoot, I've done that for 35 years and never had one blow because of it. Something else to check for. Check to see if you have both an integrated AND a plug in card. I've had many machines that had both, but only one could work at a time - plug into the wrong one and strange things happen.

Hope this helps a little. Good Luck.

Ok three of you mentioned my grphic drivers. Lemon13 mentioned re-installing drivers. Can you help me figure out what my drivers would be and how to reinstall them? Is that where i remove them from the device maganger or from somewhere else. Because as i mentioned in my first post i allready removed monitor entries from there.

Here's a bunch of specs from some program that lists it all off, it's an exerpt. I hope needed info is in here. Is there a difference between video/graphics/diplays adapter?;

Would that be all the same drivers? Can you help me find those drivers with this info? I would have to burn them to disk at the net cafe and load them up at home.

Wahnula: Wich VIA chipset drvier should i use if i 'm on 98SE??? where is that located.


peperint: [/p] Haven't made any CMOS changes recently, bu tdid several months ago to set it to boot from floppy incase of emergency.



Thanks for your time, will check back at net cafe again day after tommorw.

If your specs are correct, then what you have is a plug-in dual port video adapter that is capable of driving two monitors in a panoramic mode (much like the old wide-screen movies did back in the day -- we used to call it Cinerama). Check out the above link for more information or just try googling for 'Asus agp-v7100' or 'nVidia geforce2 mx'.

http://www.nvidia.com/page/geforce2mx.html

You can find drivers under this url. It should have all the drivers you need.

Good Luck

 

[Keith777]

The NVIDIA site only had listings for geforce 6 serieis of drivers, no longer has my Geforce2 drivers, guess they're too old:

http://www.nvidia.com/object/win9x_81.98.html

But, luckily I remebered I had to update my drivers two years ago and found where my drivers where located.

C:\NVIDIA\Win9x-Me\53.04.

If i remeber correctly that was the driver is need to use with my chipet driver wich wasn't that current.

Anyway, i found the driver-installation program from when i installed those and used it again. It told me that driver was allready installed and if i wanted to overwrite, i said yes. Then a few steps later i got this message:

"Setup was unable to locate any NVIDIA graphics chips on this system. The
Installation will be terminated."

So even having drivers to reinstall, something is still wrong. Allthough the NVIDIA Geforce is still listed under 'Display adapters' is the device manager so it's showing up there.

Unless it can't locate it because i'm in safe mode. I wonder this because my PC isn't recognizing my CD burner insafe mode. I figured I should back up my files on burned disk incase i need to re-format. I've used my burner in safe mode before but it's not showing up now, i click under "MY computer" and there's no D: drive. When open "nero express" , my burning software, it's says:

"The Win-ASPI file '?.?' cannot be found, therefore you can currently select only image recorders. The missing file is one of the Windows 95/98/Me files.
Please fix this prob and restart Nero. [Error 16: No adapters!] "

i know this is a seperate issue then the Monitor prob but am bringing it up incase its related.

A few little questions that might help:

How do i freeze the screen during boot up becuase i think something has changed about
the text but it goes by too fast for me to see it.

How do i enter Cmos or bios to check settings there? I did that ages ago but forget now. Anything to check?

Would anything in my emergency boot disk be useful in this situation?


Again, will be back day after tomorow, as i'm doing all this from a net cafe.
Thanks for your time.

Did this monitor/computer combo ever work? If not, the refresh rate on the computer may be too high for the monitor. Safe mode is 640x480, Windows may be set at something higher.

 

[Keith777]

Yes micker3777 , this combo always worked and I have changed the refresh rate in years.

Can you tell me how to enter "cmos" and check that? what would i look for exactly? Is there a differnce betwwen CMOS and BIOS? How do i enter those two modes?

Still wondering : How do i freeze the screen during boot up becuase i think something has changed about
the text, wich might provide some info , but it goes by too fast for me to see it.

As i said in my last post i found my NVIDIA drivers and reinstaled them and it did not make difference. Any other suggestions anyone?

Thanks for your feedback.

Hi Keith,

Did you manage to find out what the cause was?
I developed exactly the same problem over the holiday, and with the same hardware config...
Please let me know.

 

[piperent]

It's 'piperent', not 'peperent' , and to enter into CMOS setup you usually hit the 'delete' key right after the POST completes (the screen will generally give you a 2 or 3 second prompt). On other machines, it might be the 'F1' or 'F2' function keys. When in doubt, just try hitting them all when you first see the screen display showing you that the video is working. You'll eventually get in there.
