VGA PCI controllers

I was in my device manager & switched the "VGA CPU to AGP" driver to "VGA CPU to PCI" driver. After reboot... my monitor will not work when Windows XP boots. It works in CMOS, but goes black after XP loads. How can I fix this?

    Thank you for your response, but I've already tried to boot in safe mode. In fact... I've tried every option on that menu. Still I get nothing. There's still a signal, but the display is black.

    Also... I have an on-board VIA/S3 Unichrome Pro IGP display adapter. But I do have 2 other video cards.

    (1) 3D ATI RAGE PRO TURBO AGP (ATI AMC Ver. 2.) w/ impact TV2 tuner

    (2) Unknown nVidia card

  • kitty2427 Apr 17, 2008

    I'm using the onboard right now. It's the only one I get a signal on. I removed the other two because I wasn't even getting a signal when I would connect to them. I was also getting the bios beep error that my video card was bad. But I'm not sure if that has something to do w/ the crontrollers I switched in the first place & the connection internally... is not there. So I'm back at square 1. Atleast w/ the on board I can see & mange the CMOS. Whatever I did... it's in Windows only & I don't know how to roll back the driver w/o entering Windows itself. Is there a way to do it from the bios? Or even a system restore? Whatever I do... it needs to be outside of the windows program so I can see it.

    Kind of. I have the 5 CD's that Acer sent me plus the monitor CD. But they're Acer CD's only w/ Windows XP on them... not the Windows XP CD's. I contacted Acer & got a response, but they suggest I do the Acer eRecovery. But that wipes out my C: drive. I don't want to loose my pics & docs. Everything else is replaceable to an extent. I have a back-up CD, but I'm not positive on when I made it. Had to of been a few months ago or more. Will those CD's work as a "yes" answer for your idea?:)

  • kitty2427 Apr 21, 2008

    I know it's rediculous. They give me useless CD's, then post a sticker on the side of my computer tell'n me my registration code for Windows XP, but don't send the CD's that would be usefull to me. Yes I have a friend that would do that. Infact I just redid her computer for her. It belonged to another friend of mine so I needed to redo the system so that she could buy it. But I don't have a floppy... I would have to do the DVD's. She also has Windows XP CD's, but they are registered in her name. Would that matter for what we would need them for?

    Just wanted everyone to know that I tried my ATI(PCI) card anoe more time... & IT WORKED! Got back in & fixed. Thank you very much! I'm one happy kitty:)

Reboot in safe mode. After you boot, hit F8 several times to get to the boot menu. Choose safe mode and hit enter. After it's done booting, go into device manager and reverse the change you made. If you're using a AGP card just make the change in cmos. If you're using a PCI express card do the same thing and install the drivers that came with. Windows might have the correct driver for your card. If not just let me know and I'll get it for you. If this fixed your problem please rate this as fixed. If not, don't rate yet, just add a comment letting me know what happened and I'll be glad to help you further. Thanks.

    OK. Which video card are you using?

    1)The on board or

    2) the ATI Rage 3D or

    3) the nVidia ? Which one is in your system. I know the on board has to be, but do you have one of the other two pdysically in your system? If you do, you have to disable the on board video. Let me how you have your system configured right now so I can better assist you. Thanks kitty.

    Do you have your Win XP cd? No, we're not going do a complete re-install like a few experts suggest half the time.So do you? Just say yes please.

    Sorry.. That doesn't count.. I don't know why when thet sell you a pc they don't include the windows cd. We could have used the repair fuction on it and bada bing bada boom..done. There's other tricks to try. One to try, now this is just one amongst a few, do you have a friend that would be willing to put your hard drive in their machine, make a few dvds of the data you need and then you could put it back and use the restore cds? Another, do you have a floppy drive and do you have a friend that has a floppy drive that is running Win XP? Let me know so we can get you up and running.

    Wanted an email 'cause it's easier to keep track of and I haven't been feeling well but I have a few people that I still want to help and you're one of them. You sound knowledgeable about pcs. The major thing is not losing your data. Is that correct? I asked you before but I don't think I received an answer, do you have a friend that would be willing to let you put your hard drive in their machine, burn a few cds with your data so you wouldn't lose it and then you could put your hard drive back and use your restore cds.Let me know please. Thanks.

Boot up press F8, select safemode, select administrator.
This will boot up your computer with limited drivers and in a separate account, not the one you altered.
Change settings back and apply. Reboot and log in to your account. If it fails to load the os reboot back in to safe mode under your account and change settings again.

    There may be another work around for you fromdos to boot into windows.

    press F8 on boot up and select VGA SUPPORT.
    this will auto select the lowest resolution for any monitor.

    Once in right click on an empty area of your desk top, left click properties, left click settings, reset resolution,apply and close out.

How do i adjust my vga cpu to work with my svga monitor?

Your computer should work fine with the monitor. I would guess that the XP display settings are off, either the resolution or monitor refresh rate.

Rather than tinkering with the display settings, it may be easier to delete the video card from device manager, then reboot and let Windows configure itself. You can then tweak the settings by right-clicking the desktop, properties, settings (I think), or thru Control Panel, Display (I think). I haven't run XP in a while.

How do I install VGA PNY VCG62256PXB 6200 256M RT

heres a link to a video tutorial from PNY's site.

after you have disabled your current adapter in device manager, you will need to verify that your system's primary display adapter is set to PCI in your BIOS.
1. Reboot computer. you can enter the BIOS settings by pressing F2 key right after post during the boot process.

After you have set the primary display, reboot and then shutdown. unhook power cord and monitor cable

2. find an open PCI slot and remove the slot cover from the back of the case. Insert the card, making sure it is seated properly (no gaps, not crooked)
3. attach monitor cable to the VGA port on your new card.
4. boot system. you will get the message that windows has found new hardware. cancel all the prompts that come up.
5. insert your drivers disk that came with the card. follow through the will have to reboot after the installation.
your video card should be working now. 

hope this helps

PCI video slot changed to AGP video slot

First, install the AGP card in the AGP slot. Plug the monitor into the new video card.
Second, power up and press the F2 key to enter Bios.
The system should default to VGA but through the new and only video card available. If this works you will be able to save the settings and exit. It will reboot as normal. When prompted use the cd for that card to load the drivers.
AGP was a short lived concept and aren't that many to chose from.
If you don't get any video at all, the problem may lie in the motherboard and not really repairable.
Good luck.
