Display Adapter Not Showing In Device Manager
Mar 23, 2009
I just bought an EVGA nForce 730i mobo with onboard GeForce 9300 graphics card. I installed vista ultimate 32 bit and the first thing I did was install all the drivers from the disk that came with the motherboard. For some reason I can't find my display adapter in my device manager list and I don't think the driver from the mobo disk is installing properly but I can't check that because I don't see the adapter in the device manager list. Any idea on how I can fix this?

The Microsoft 6to4 adapter showed in the device manager that it was not working properly. If you look at yours it may show the same. I think I disabled it trying to update it. This was before I found this short sweet article from Microsoft. Does anyone know if I will experience problems in the future when this new technology gets more prevalent? If so, how do I get it back. I followed the instructions that a vista pro gave me to fix this problem and it shows in the reliability monitor that it was installed...but it is not showing int he device manager. Would it be installed but not show on the device manager?

I have had installed a Pentium D Extreme Edition 840 3.2 Gig CPU, in Device Manager it lists four CPU's, two as Pentium D 3.2 and Two as P4 3.2, is this what should be showing, or has the tech missed something in installing?

I got a Nvidia 8400GS When i got the PC but brought a Sapphire ATI Radeon HD 3870 X2 / 1GB / PCI Express 2.0 / Graphics Card. My brother took out the Nvid card and then formated the PC to make sure that all drivers where uninstalled then put the ATI card in. In divice manager under dispaly adapters there is standard VGA Graphics Adapter and further down the page there is "Other Divices" with Video controller. When it installs these some times the standard VGA Graphics Adapter fail but the video controller succeed but with error. saying. "Incompatable display Adapter has been disabled. At least one display adapter on the system has been disabled because its not compatible with the driver for the VGA adapter". lso i carnt change the resolution above 1024X768. Also my Graphic card is a Sapphier brand but in the windows update its looking for ATI Technologies Inc. - Display - ASUS EAH3870X2 Series

Can not get my HP 7400 scanner to work after upgrading to Vista Ultimate 32 bit. Not the hardware - works fine under XP pro using same hardware configuration. Did a clean install, installed motherboard BIOS updates, scanner BIOS updates, Vista updates and the correct driver from HP. The scanner installed and Device Manager says device is working properly. When I try to scan, scanner initializes, starts to scan then locks up. Then can no longer be seen. ASUS M2N-E motherboard with AMD dual core. Other than that Vista works OK with the rest of my system

i have installed the correct driver for this belkin bluetooth usb dongle model: F8T012XX1 but in device manager, it has the belkin device and microsoft bluetooth enumerator, which is great. but when u get further down the list. it has a tab named "other devices" and then a subtab with "bluetooth peripheral device" which has an exclemation mark on it. i have searched for driver software using the update service but it cant find no update. i have looked for the name of the manufacturer but found nothing.i then disabled the unknown device, and sent a picture to my mobile phone. which confirmed that it was not the belkin bluetooth device. so i uninstalled the unknown device, restarted the computer. then when i logged in, it said that it had found a new device and wanted me to find the CD that came with it.

I know this is a repetitive topic, but I can not seem to figure this one out. It is a HP Laptop DV9815nr. I do not know much about it as it is not mine, but the problem is the audio was cutting out and now there is nothing. The computer is not recognizing any type of audio device installed. Even in Device Manager, there is no option for Sound, game and controllers. I have tried downloading the driver and installing, but no luck there.

Setup: New Vista PC (bargain-rack special - a bare-bones office machine with Vista Home Basic) has a built-in VGA adapter. I want to do the two-monitor setup, so I plugged in my ATI video card as the second video driver. Problem: When I boot the machine, I get the following error: Incompatible display adapter has been disabled. At least one display adapter on the system has been disabled because its driver is not compatible with the driver for the VGA adapter.
What I find odd, though perhaps it is not odd to you, is that the internal driver was the one disabled - the ATI card is now defaulted as the main (and only enabled) driver. In Control Panel, it does not say that the drivers or controllers are disabled, but instead that there are problems. Clicking on Troubleshoot does nothing at all.

I had been running Vista Ultimate x64 for a few months and recently found that I can only use the original USB mouse?! Installation of any USB mouse would show a new "USB Human Interface Device" in Device Manager but it just won't work. Installation of the very same model of my original mouse didn't work neither. So basically I am stick with the current mouse?

I have 3GB of Ram installed, but only 2gb shows up in task manager. The rest of the system recognizes all 3gb. I'm trying to use Adobe Premier Pro CS3, but it keeps crashing due to lack of memory. Page file is at the max. This problem only recently occurred. I used to be able to view all 3gb in task manager, but for some reason it doesn't let me anymore. Is there a way to enable all 3gb again to be used for applications?

Ok so for a few days now my audio has not been working, I use it quite frequently with itunes and dvds etc but not ever very loudly. I've been on my laptop's website and have tried everything they've suggested except for system restore, and nothing has worked. I've made sure my computer is completely updated, I have downloaded the newest update of the audio driver from the website, and still no luck. In Device Manager it says everything is working, I have no error signs either. The mixer picks up the sounds when I test for it, I just can't hear it! It doesn't work with headphones either, although when I plug my headphones in and pull the socket in and out a little bit I can hear crackles in the headphones.

I just got a new computer with 64-bit Vista Home Premium, and am having some issues with devices. When I connected my Lexmark X6100 printer, Vista recognized it and even took me to the website to download drivers, which I then installed. when I bring up Printers in Control Panel, the Lexmark is not listed. The X6100 also includes a scanner which again Vista found, but it directed me to the same download as for the printer (not surprising). There is an entry for the Lexmark X6100 in my Start Menu, but the only option there is to uninstall the software.
My old computer ran XP Pro and the Lexmark worked perfectly there. There was even an icon in the system tray that appeared at startup. A second issue has arisen with my webcam, a Logitech Quickcam Pro 5000, which Vista also recognized, and there was a prompt which looked as though it was from the Logitech driver asking for a disk which I did not provide, because I didn't think it was necessary. The cam also worked well under XP without any additional software installation.
Vista's Device Manager reports that both devices are working properly, but I am unable to access either of them. I also installed a program called PDF Factory which I used as my default printer on my old computer, and it's working just fine - and it shows up in my Printer panel.

On an HP m8120n, I had HP replace the DVD drive that came installed (didn't do DVD-DL). New DVD drive worked fine for 2 months, watching movies, burning CD's and DVD's, but now can't watch commercial (legit bought or rented) DVD's. Quick search of these forums I found this link - which I d/led and ran. It stated there might be a problem with the ASPI layer. Quick search of that turned up something about turning DMA off (or on, forgot what) and that I needed to go to Device Manager and find the IDE ATA ATAPI tree. Here's the problem, I don't have a +tree that says IDE ATA ATAPI. Should I?

Suddenly I can't access Device Manager via Control Panel/System. When I click on the link that should open the Device Manager, nothing at all happens. The link has been deactivated? I can still start the device mgr by running the file directly from Win32.

I am having an issue with the hd 4350 card. I read on another post that re-installing windows solved the problem however I have an on-board video unlike the said poster. Problem: Device manager only lists the on-board display adapter, not the 4350. Heres the funny thing, When I run my diag program (pasted below) the 4350 is actually listed. I did RMA the first one I received and was disappointed to see the replacement doing the same thing. Anyway the reason for this post is to find any other possible solutions before I go an re-install windows. Wiping my puter is really the last resort for me but at this point RMA is no longer the issue.

My Dell XPS M1530 Vista SP2 all of sudden had the icon for volume/sound disabled. When I did some investigating;
- The machine seems to be working fine but it appear to be very slow, backing up my machine took for ever, sometimes it see my external disk and other times it didn't
- I received a message stating that I need to check windows latest update and I tried to install an important SP2 but it failed
- Device Manager is showing no device, it's looks completely empty
- called Dell support, they were unable to figure it out, even though I have 3 year warranty they are saying they will have to charge me for s/w support, which was never a problem before.
- I tried to do restore but it states there is no restore points
- I tried to see if I could start the Plug & Play but it gives error
- I tried to install the Audio driver from the Dell Disk and that gives errors

I installed a 2nd hard drive and Vista found its drivers. The drive is showing up in Device Manager but I can't figure out how to access it. No letter is assigned to it. If I look under 'computer', C is my original drive, D is the recovery drive & E is the DVD/CD drive. No other drives are listed. Device Manager reports the drive is working properly.

1.) I don't know if it's important, but "npkcrypt" is apparently either missing or damaged, according to Device Manager..... I imagine there's no file that's missing that can be GOOD, but I figured I'd ask if there's a way to fix that, or it could be relevant to problem number 2.....
2.) Lately when I shut my computer down, 50% of the time if not more often it takes forever to shut down, doesn't shut down, or will but claims that "windows has suffered from an unexpected shutdown"..... even though it shut down because I TOLD IT TO. When it comes back on it says I suffered a BlueScreen, which I've only actually SEEN happen one or two times, but it claims it happens almost every time those other problems occur.
3.) Another thing I would like some aid with, if possible.... there are programs I want to prevent from running when I start my computr, but when I go in to stop them, it won't let me, stating that the scan on them leaves them "unidentified," so I can't make them NOT start along with my PC. Only Microsoft programs are capable of being stopped.... any way around that?
4.) I think the problems with 2 may be related to some downloading done on my part recently, but I have McAffee AND all my windows stuff on maximum security.... not a peep from ANY of them.
5.) When the start-up/shut-down issues started happening a few days ago it also said my CD-ROM driver was messed up, and I thought that was the ACTUAL problem, but when I fixed that, it still didn't stop the Bluescreen issues from occurring. I don't know what to do to fix ANY of this, but if someone does, or could AT LEAST explain what the hell it all means, that would be GREAT.

My first post here and unfortunately I'm posting because I've stumbled right into some technical issues with this fresh desktop build.
First off, comp specs so we know what we're dealing with:
MOBO: ECS P55H-A Black Edition
CPU: Intel i7 860
PSU: BFG 800W
Graphics Card: POWERCOLOR AX4870 (two of them)
OS: Vista Home Premium x64
I have everything hooked up properly and can verify both PCI-E slots are working and both video cards are working as I've tested them all separately. I'm using the latest CCC and drivers available.
I initially hooked up just one card, then loaded Windows and it detected it just fine, so I installed the drivers. Everything was just fine, so I shut down and installed the second GPU and hooked it up and attached both Crossfire bridges to the two cards. Nothing I have done since will cause the card to show up. I tried removing the bridges and rebooting also to no avail.

I have been asked to look at a problem with a computer at our local social club. It's a Dell Inspiron 530. It was not showing anything to do with Networking in the device manager so I went to the BIOS and enabled the network.
When I restarted Vista this time the network device was showing in the device manager but that there were no drivers installed for it. If I can manage to locate the Vista installation CD would that help me to get it working? If I cannot locate the original CD would it be okay to use my own CD instead?

I have an HP dv9208nr laptop which has worked perfectly for me until recently. A few days ago after closing the computer and opening it back up i noticed that the wireless wasn't working. Obviously i checked the switch and the switch was on but the LED was orange indicating that wireless connectivity was turned off. I tried restarting and no luck; after a few other simple fixes didn't work; i went to the device manager and noticed that the wireless card wasn't in the list as it should have been. I tried updating the drivers; nothing. HP techs sent me a link to a service manual and instructed me to reseat the card manually, reset the BIOS, and reinstall the drivers. It didn't work. the next day the computer had found the card as new hardware and installed it. it worked fine for a day; then the same thing happened again.
