Question about Acer Aspire T135 PC Desktop

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?

  • kitty2427 Apr 30, 2008

    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.

Pvm890m mother board vga driver not working in windos 7,solution please.


I am assuming you are using the internal vga adapter installed on the motherboard, and not an expansion card in the AGP slot. If you are using an AGP card, the motherboard VGA driver will do no good; you must load the driver for the add-in card.

There are a few things to check. First in the CMOS Setup, on the "PCI/Plug & Play Setup" tab, ensure that the Primary Graphics Adapter is set to PCI. That selects the onboard video adapter.

Then, reboot the system into SAFE MODE. Use the F8 key, to get to safe mode during the boot process.

You need to go to the Device Manager window. To do this, click START, right click on COMPUTER, click on PROPERTIES, then select DEVICE MANAGER. Expand the DISPLAY ADAPTER listing. On the listed adapter, right click and select PROPERTIES, Select the DRIVER tab. Look to see if there is a ROLLBACK DRIVER option. If so select this and let the system go back to the previous driver.

This is an old motherboard, made before WIN XP. Motherboard manufacturers will normally only supply new drivers for two iterations of windows. So there is not any chance of getting a driver from the manufacturer for anything much later than VISTA. However, WIN 7 has default drivers that will operate most legacy VGA adapters. The rollback you did (if you did) probably took you back to the driver that WIN 7 placed there when it was installed. ou may have to live with it.

Vga agp geforce fx5500 driver


Click start control panel administrive tools computer management device manager scroll to display adapters + to expand you might see a yellow question mark ? or exclamation mark ! or a red x right click select reinstall drivers

If your computer came with a motherboard disc the drivers could be on it

Want to make sure your drivers are in place and no errors have occurred? Simply click start right click on my computer select properties then select device manager scroll to Display Adapters and click on the small "+" you should see the model of your PCI Express graphic card there. If there is a problem with it, a yellow exclamation mark should appear besides it. If you don't see it everything is OK and your card is working properly.

When I plug my monitor into my video card i get "no input signal" yet if i plug it into the onboard slot it works.could my PCI-E slot be bad?


Did you add a video card? If you have an AGP slot, it is best to put the video card in it. If so you need to go into the Device manager. Remove, disable or uninstall the onboard VGA driver. Go ahead and remove the PCI video card driver as well. Power down PC. Make sure monitor is hooked up to the Video Card, not onboard VGA. Power on PC. When Windows loads, it should detect the VGA card first, but if it detects the onboard first, ignore and don't setup onboard first. When Windows detects the card, load the necessary drivers when prompted. There is no need to reinstall the onboard driver for the video unless you wish to hook up two monitors.

I believe the problem is from the herzian synch windows wants to achieve, either too low or too high.
You ought to try with a different monitor, either to set the synch or to make a analasys if it's another problem we're facing, like graphics card or motherboard itself.
