Unknown Device Drive: New Video Card (radeon HD5570)?
May 24, 2010
I have a bit of a problem, for some reason my system is showing "unknown" in my device manager, the only hardware that has been installed on this system is a new video card, (radeon HD5570) that seemed to go in without a hitch. Simultaneously, with this appearing I started having issues with windows media player not play .mod files, using web help it says that I need to update my audio drivers, but according to Dell they are good. Would really like some help with this.

I bought a Visiontek ATI Radeon X1300 512MB graphics card last night and I can't get it to work. No display shows up on my monitor. This card needs an additional power supply which I have supplied (i.e. used one of the extra power plugs from the power supply in my computer). It sounds as if my computer keeps restarting, but can't say for sure since the screen remains black. It works fine when I put back in my old ATI Radeon 9200 series card, but if I try the new card, NOTHING!!! If anyone has this card and has had the same problem, please give me the solution to fixing this.

I just formatted my computer and have realised that my screen is around 800 x 600 i think. I want it to be 1024 x 768 and everytime i adjust it to be like that, it resets to 800 x 600. I have a Radeon 7000 graphics card.

I created a mess (but I'm learning more each day), and after a week got it going at least, but on boot got messagae "primary hard disc drive 1 not found" which required clicking F1 to continue. I ended up reinstalling XP, got everything up and running, but still have the HD message at each boot. I've passed all of the diagnostics in Set-Up, and found nothing on any of the troubleshooting sites that helped. Set-up says: Primary Drive 0 - Hard Drive; Primary Drive 1 - Unknown Device; Secondary Drives 0 adn 1 are both CD-ROM Readers. Everything works just fine, but I'd like to figure the drive problem. I had to create a partition for the reinstall - had no choice.

Recently I was playing a game, when my screen froze. I then shut my computer down to restart it, used it a few times (in 4-bit safe mode), then after I shutdown again, I cant log back in... it just freezes and the screen flashes, I cannot boot into my computer setup (default f2) or into safe mode (default f8), however I can run the XP cd and get into the recovery console, is there any way that I can change the boot sequence from the recovery console? The screen is dotted with a bunch of dots up and down the screen in columns, and is in 4-bit video mode.
I have a Dell xps gen 5 with xp home.
the error I get is:
"Error: Cant enter setup. Video Mode 103 not supported by this video card."

Last night I installed ATiTool 0.24 over my 0.25 version (stupidly). I also did a BIOS update and installed Cat6.3 and then AVIVO converter. When I rebooted, I had this new PCI device requiring a driver,but it's an unknown device and doing an auto update helped me.I can't get rid of this pesky PCI device (tried uninstalling but Windows detects it again after restart/boot-up). All my stuff is working, so I don't know where this critter came from?

I hooked up my Xbox to my PC to play online using my monitor, only to find out that my NVidia Geforce4 Ti 4200 can only display a max resolution of 720x480 through my capture software, and this ain't good enough for me. Does somebody know of any specific card/adapter TV Tuner that has an S Video input and could give me resolution over 1024 pixels under $100.

I was working away on my desktop tonight, and suddenly the monitor started freaking out. Here is a video to show you what's going on at startup, When it happened I was working in Cubase. I'd just reset the audio driver, and it started doing like in the video. After a little bit, the signal cuts out completely. It's not the monitor, I've checked with a spare and it's the same. I don't have another video card around at the moment, but I'm wondering if it's likely to be an issue with the hardware, or software/virus type stuff.The computer is XP, 2gb ram, nVidia Geforce card (sorry, can't recall which one) etc. Incidentally the card itself looks fine, ie it doesn't look like it's shorted or anything.

I'm using Win XP SP2 . I installed a second CD rom drive which was obviously no good because it caused the other one which is perfectly ok to show up in the bios as an unknown device. Both showed up in the bios as unknown device but the the first still showed up in system hardware the second one didn't.I removed the second one from the computer and the first one then showed up accordingly in the bios as the proper device but the bios is still saying the second one is an unknown device. Every time I start my computer I get the message secondary device missing press the F1 key to continue.

Just put together my new system and all is working well, but I am left with this unknown exclamation in the "device manager". I can't figure out what it is.
The only thing device manager says is,Location: on PCI standard ISA bridge The drivers for this device are not installed. (Code 28) and in the conflicting device list it says Memory Range FED00000 - FED00FFF not available.

i installed an usb device,and all the drivers for it,it worked for two days, it was recognized.Now it will not recognize the device.I have tried uninstalling and reinstalling the device drivers, all the software that used the device. and even tried to install the driver by locating with 'have disk' browse. i have tried all the directories that the drivers were installed to, and then some. and also the install disk. Device manager says that its an unknown device, and theres no problem with it. but will not update to the proper drivers. How can i alleviate this problem short of reformatting my computer.

I have a Gateway 710X running Windows XP Home Edition which has been patched up-to-date.Connected to this is a Western Digital 80Gb external hard drive Model Nr WD800B005-RNN) The drive had been connected to the USB port for a long time without any problems in access. Tonight, however, it seemed to have been discovered as disconnected, and we reconnected the USB cable.Upon reconnection, we get pop-up windows in the lower right corner which state: (1) Found New Hardware: USB Device then switches to (2) Found New Hardware: Unknown Device then appears (3) Found New Hardware: Your new hardware is installed and ready to use then appears (4) USB Device Not Recognized

I installed all the Windows updates and loaded the drivers off the utility disk that came with the motherboard. I also got the updates from the GIGABYTE website. The utility app shows all drivers are installed correctly. It took me a couple of days to get audio to work because the initial driver load got corrupted somehow and it wouldn't let me reinstall until I deleted the driver's entry in the registry. After that I was prompted for the driver again and it installed fine and sound finally started working. Everything appears to be working and there is only the one Unknown driver in my Device Properties and it's really irking me. All my drivers were installed correctly in my previous installation

I just installed Windows Xp on a puter. After installing all the drivers including the video card drivers from ATI's website the computer discovered an "unknown device on ATI Radeon X700"The motherboard is a gigabyte 8I865GME-775-RH and obviously a X700 Radeon Video Card. AGP drivers, chipset drivers and the like are all installed. The video card showed up as an unknown device when I first installed, I put in the catalyst drivers and it detected successfully, upon reboot this new unknown device came up and I can not seem to find any drivers for the thing. I tried reinstalling the catalyst drivers as well to no avail.

I don't have sound and haven't for the past few days and then this morning a Found New Hardware Wizard keeps popping up trying to install software for an Unknown Device on High Definition Audio Bus.In the Device Manager, there are yellow question marks near Other Devices and then below it, in sub categories is a list of at least 20 (!) Unknown Device on High Definition Audio Bus.In the Audio Device section, there are NO Playback Devices, NO Recording Devices, No Midi Playback and the same in the Voice section. Usually I have Realtek listed there.

All of a sudden, the imaging devices attached to a computer with Windows XP Pro SP2 are showing up under the Unknown category in the Device Manager. The
devices are listed correctly by their names under Unknown, but the software won't communicate with them.Windows can see the devices, but it does not know what type of devices they are. It is only the imaging devices. One is a Canon 4200F Canoscan scanner, the other is a Sony Camcorder, and the third is a hardware capture device (Pinnacle Moviebox). The Canon scanner is a USB 2.0 device, while the other two are attached through firewire ports.

I installed a fresh copy of WIN2000 on my IBM Thinkpad A21m but I am having a problem setting up a device in Device Mangager. I have no idea what is going on.
When i reboot the laptop it prompts me that it has found a new piece of hardware and it wants me to install the driver for it. The problem is that I have no idea what device it is since all the devices that should be working are working - so i don't know what to do.
The clues that I have noticed that might help:
- the laptop takes a LOOOONG time to boot up (3 or 4 mins), and is sort of sluggish in operation (compared to how it ran when i bought it)
- my internet connection is super slow ( I have a DSL router that serves 3 computers incl. mine, the other two have XP and everythign runs smooth)
- the unknown device says it is located on the the "Microsoft ACPI-Compliant Embedded Controller"
Would any one know what Device this "Unknown Device" is??? I just need to know so i can install the driver so my system can run properly.

Is there a way I can run iTunes, for instance? I know you can simply install iTunes 4.7.1, then maybe someone can tell me how to turn the .dmg file that the zip releases into an iso that's actually readable by my dvr drive?
a way to use my video card under x64 -- going a step further, the remote that came with it?

I wass just wondering if someone could tell me if I am on the right track or not Power supply went out on the computer Put in a new powersupply and everything comes back on except the monitor.The monitor lite is green at first and then turns to amber and nothing comes on.I tried another monitor and it does the same thing so I am guessing it is the video card.I would not think it would be the cord to the monitor cause that means the other monitor cord would also be bad and the odds are good that that would not be the case So am I on the right track that it would be the video card not getting from the tower to the monitor?It is a built in video card so I would have to get a PCI Video card cause there is no AGP slot.
