Cd Rom Showed Up As Unknown Device In Bios?
Feb 6, 2007
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.

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?

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.

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 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.

I am trying to set the boot device for a thinkpad T23. Nothing is password protected. When the BIOS setup CDROM is top, with no + next to it, and followed by hardrive and them removable. HD and removable does have a + next to it. CD is bootable, why won't the thinkpad boot from the CDROM?

My sons friend dropped his computer off to be cleaned up. GOt into some areas that appears to have taken over his system and his Internet service canceled his account and told him to clean up his system. It was home built using a MSI mb MS6702 / K8TNEO FIS2R or K8TNEO FSR not sure which.I was going to format his system and reinstall his XP but as soon as you start the system you get the No Device Found message and then a BIOS not installed message. If you try to get into BIOS using MSI's instructions (DEL key) it will not go into BIOS so you can set-up the boot sequence etc. If you let the system continue to boot the system will boot into XP with no problem.

I have a Media Center PC, and the icons always on my desktop only showed the words. This is kind of hard to explain, but now there is a blue box in which the words are in. For Example, My Computer. Before that is all you would see under the little icon; now you see a blue box with white words inside of it saying My Computer. I messed around with all the view properties with no luck

My PC crashes some times , sometimes playing games but other times I am just playing old games (MAME32 etc.) that do not require any CPU power. And sometimes I am just surfing the net and listening to music when the screen appears. One of the screens I recorded showed the error: 0x0000000A. I scanned the registry with Registry mechanic but it crashed again after some time. The error this time was 0x0000008E (parameter, parameter, ..., ...) I cant understand the reason. My Power supply is ok since it is relatively new and has nothing to do with the crashes (it crashed before and after change of PSU).

I tried to start it up and it takes forever to load. It takes a couple of minutes to open any of the icons on the desktop too (Mozilla, Word). I tried to clean up as best I could. I ran some spyware programs and antivirus and nothing too much showed up -- no viruses. It takes so long to run these programs that I go off and do other stuff and come back hours later and the scans are still running! Is there anything that you can recommend to get the laptop running as it should?

Is there anyway to see the BIOS boot order (1st CD, 2nd Floppy, 3rd HDD) through windows XP (possibly a registry key or something)? I ask because I need to make sure all of the computers in my department are set to HDD first and not CD incase they have a non-bootable CD in the drive and a power outage (or Windows Update) causes a reboot.don't want to goto every computer, and would like to do this all remotely.

once the on button was pushed, it came up with the BIOS screen asking for the password.I removed the CMOS battery, which allowed me to change the Password so I can get onto BIOS now. However, when I boot now it just comes up with the BIOS screen.I set HD to boot first, aswell as setting the clock and date. I then ask it to save and quit, after which it shut's down, and reboots, only, BIOS keeps coming up. And I need to get this sorted asap

I have had windows XP Pro installed, updated and running fine until about a week ago. I was away from home for about a week and left the machine plugged into the mains but powered down. When I returned home to boot up, it kept doing things like constantly hanging on parts of the bios POST screen, eventually booting up after thirty or so complete restarts. It finally booted into windows but after the last shutting down, it will now not boot up at all. I have replaced the bios battery and reset the bios several times.

When I turn on my computer, it does the bios check, then goes into the bios screen on its own. I have checked all of the bios settings, and see nothing set wrong. The only way I can get itno my xp pro system, is to use "F8" during the bios check, the select my hd from there, then it seems only half of my programs work, and it also seems to be randomly changing the programs that do not work, when I do this.

I have a Sabrent SBT-EKU25 external enclosure with a 2.5 inch hard disk in it. This is a USB 2.0 drive and whenever I connect it to USB 2.0 port, it is not recognized (or "recognized" as an unknown device" ) on all my machines. It however is recognized as a drive and works fine on one laptop which has only USB 1.1 ports.I have tried separately powered USB hubs as well without success. So I don't think it's a power issue.I have even tried deleting all USB devices in Device Manager and let the machine rediscover them.

Got a bit of a problem with my housemates pc.A friend gave him some extra RAM, i checked it out and it was crucial 512mb pc2100 CL2.5, and although it didn't match his exsisting RAM it seemed to me that his mobo would only run the FSB at 200mhz anyway so i went ahead and fitted it.It worked fine I then noticed his system temp was running a little high (60-65 degrees), so i took his heatsink off and cleaned the dust and refitted it with some new thermal compound.I added too much and the temp went up. To nearly 90 degrees.I shut it dwon as i didn't want the cpu to pop, cleaned it off, reapplied less compound and figured this would work fine.Now we have the problem. Most of the time: Power on and nothing happens. No bios, no beeps. Occasionally: Power on, i jump into the bios, the temp looks fine (30-40 degrees) and then it freezes right there in the bios after about 30 seconds to a minute.This sounds like a heat issue, but the last temp reading before freeze is 33 degrees.?I've double and triple checked that the heatsink is on properly and thats fine. I followed the official guide on how much compound to use (a blob the size of an uncooked short grain of rice).
