Monitor not receiving signal

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.

I have had a similar problem. This happen when I altered setting in the BIOS to overclock memory and CPU. Try entering the BIOS and setting default setting. I am not sure if the Power Supply to my motherboard had anything to do with my problem. Would also like feedback if possible

 

Here's a bunch of specs from some program that lists it all off, it's a exerpt. I hope needed inof is in here. I sthere a difference between video/graphics/diplays adapter?;
Would that be all the same drivers? Any this info is by hueydewey request.

Not sure if this is applicable for WIN98...

I've wondering if it is a boot problem rather than a monitor problem. If instead of booting into safe mode you select Enable VGA mode that should fully load Windows but give you minimal display drivers. I think?

On my system after the splash screen, my screen goes blank when login screen appears my monitor clicks. In VGA mode there is no click. I think at the click is when your monitor shuts down. Try the VGA mode and see what happens. You may be able to change display settings and load monitor drivers from within the full OS.

 

I had something like this too and I found out that my video driver was bad. Windows will boot to a point without your regular video driver being loaded (at least that was the way it was with my system) and when it tried to load the bad video driver everything just went blank. Just something to keep in mind for when you do get into windows.

 

As Guage said, the problem is actually most likely in the display adapter drivers not the monitor drivers. If you remove the display adapter in device manager it may help. I would have a copy of the newest drivers on disk in case they are not automatically detected.

 

Do you have another monitor you can try the computer with to determine whether the monitor is faulty or the computer. Try swapping cables aswell.

If that doesnt work then try reinstalling all your drivers for display in safemode and reboot in normal mode.

 

Will try useing another monitor but have allready tried reinstalling display adapter:

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 also 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.

 

I think your start up disk may have a selection of line by line confirmation. It prompts before loading each item and you can read the response.

Entering your bios is the [del] key; just hit after powering up until you are in.

Try this to get into Normal mode. Last couple steps may not be applicable but you could remove your video adapter and restart and let the hardware wizard find it and reinstall.

 

Actually you might try this, if it works you you would have internet.

 

Try booting in safe mode, and uninstalling the video drivers. When you reboot, windows should pick it up and reload it. The problem sounds like maybe the refresh rate and/or resolution was set too high for the monitor. Also, if you have on board video, it may be causing a conflict when windows loads the video driver... it sends the output thru the on board and not the video card. Enter the BIOS and be sure that AGP slot is set as primary video adapter... it may be worded as : Initialize Display Adapter and your choices would be AGP or PCI or maybe On Board or On Chip would be an option... in any case, find this setting and be sure it's set to AGP. It's usually under Advanced BIOS Settings or PCI/PnP Settings.....

Hey sach2, will try to re-install the display drivers one more time the way you suggested and will report results back, but as i said in my last post i reinstalled them once allreay in a different way but will see if this way you've (and hopperdave2000) suggested makes a difference.

But in the mean time...you mentioned it might be a boot up problem...is there anything that i could check to look into that? ( Just to ask ahead of time 'casue i'm making trips to the net cafe with my twisted ankle so it saves me a trip )


F.Y.I : My refresah rate was not adjusted by me , the ONLY thing that that happend was pluggin my monitor in while the PC was allready on.

Few little things:

Is there a difference between "CMOS" and 'BIOS"? Someone mentioned how to enter BIOS (press delete) but no one mentioned CMOS.

Can anyone tell me how to freeze the boot up pages so i can read whats going on there?


Thanks for all the feed back, will try all this and post back on tues.

Problem solved, with minor issues

PROBLEM SOLVED but there where a few issues and questions raised along the way wich might point to what went wrong or other problems:

What worked : for anyone else following this thread, Sach2's last post post , about setting the display to VGA in safe mode (12:09:06 23:48) so it doesn't load any or need any extra drivers in normal mode is what worked. To get me into normal mode at least. I then removed the NVIDIA display adapter from the device manager and restarted. I don't why this didn't work when i did it from safe mode but there you go. When i restarted it automatically found a driver somehwere on my PC...and not my Win98SE disk...i had no idea where it was finding it....any ideas? If this happens again i'd go get it manually.

The wierd thing is that i got a prompt saying the auto-found driver it was loading was older than the original files i had removed, and if i wanted to keep the original ones. I said yes to most of the files. So apperently it was re-loading the original files i had removed without actually useing the mystery ones they had found elswhere...'casue if there was a difference in dates then they must have been different files. I think it must have loaded at least some of the auto-found old driver and then mixed some of the original ones in with it, cause it was loading for a bit before it started prompting me about what to replace.

Also to Hooper DAVE 2000: you said i needed to go into BIOS and change the Video adapter seetings to VGA if i had "ON BOARD" video.. I checked my Bios , what I have is:

Under Advanced tab--->PCI Configurayion--->Primary VGA BIOS---> options:

PCI card or VGA crad.

It is currently set to "PCI". But i don't know if i have an "Onboard" video, can you look at my specs above and tell me? How would i check that?

Allthough the monitor is working now, so maybe i should let sleeping dogs lie.

Thanks alot...problem solved!!
