Hi,
I randomly check for unknown device. But to my surprise, my computer name is shown as unknown device and its installed date as shown as this novermber 18. How to check , what has been missing as drivers for the computer, which is working normally otherwise.
-
That's a new one for me.
What does it report when you right click on the PC icon and select Troubleshoot ?
Is there anything unusual showing in Device Manager/View/Show hidden devices ?
Do you have any restore points going back to when you last checked for Unknown Devices ?
-
Hi,
I have checked by right clicking on the icon and it shows the c: drive files in a different way. I tried trouble shoot in the right click menu, and it opens a dialog box, simultaneously trying to find drives for the device, but failing to install drivers.
Somehow, i could not enclose a print screen of the right click menu and also the diagnostic log from trouble shooting.
But when computer starts, it does not look for any device or drvers.

You could try resetting the CMOS (BIOS) which can be done by removing the CMOS battery for about 5 minutes, but as this can differ from machine to machine, you would need to Google for the Service manual for your machine to see the correct procedure as it can also include switching jumpers on a Desktop PC.

Hi,
Boggins. Sorry for late replying. You might have noticed the rain effects on Chennai city , in India has battered it totally making the city as an ISland.
All services, phone,mobile, communication , internet everything went dead including power. You might have seen about inundation the city has experienced.
I could see a flash river flowing down the street in the speed of race car. You could imagine. The rain has forced everybody indoors and when we woke up next mornring , the street was clean with heap of road materials on the cement road.
Every storage reached full and the resultant extra water flooding the street in the lower region, where it has engulfed the entire locality in its way rendering thousands without any thing to support their lives.
My locality is safe but my relatives, friends have been totally cut off without any communication. Now everything is slowly coming to normal including internet. Hence my late visit to this forum. Still the low regions has sea of water to be pumped out
I am enclosing the txt file, of the properties in the device extracted from the problematic device.Just see what is wrong.
I saw that there was a device driver of mcafee site advisor, with the name of the device code. There is no hardware id , but i enclose the details.
I uninstalled the mcafee site advisor, and still has the unkown device driver.
How resetting of bios would be responsible for this unknown device? Please see the enclosure and analyse to give solution
-
In your opening post you say it is your computer that is showing as Unknown Device which is why I thought perhaps resetting the BIOS may help.
Go Start - type msinfo32 - press enter and expand Components then click on Problem Devices to see if it finds any.
-
Hi, Yes, It is my computer. There was no power supply and internet connection that affected the communication.
The thing about chennai flood is a addition to the topic , that our city has faced. Now I hope you understand.
It is included in the text file i enclosed. The text file is the cut and paste of the properties of the problematic device.
How to know which device if it is . There is no hardware id. But the other information i posted in the text file is the only thing that i could supply.
i checked the problematic device and it shows the same information . Anyhow i will also enclose the same in my next post.
-
There hasn't been anything on the UK news that I've seen about floods in India.
Our news of late has been dominated about the Labour Party being split over a decision in Parliament whether to vote to extend UK air strikes on ISIL in Syria and the shootings in San Bernadino, but we have had floods and gales which has wiped out power supplies, although not to the extent as your country would seem to have experienced.
Fortunately my local area hasn't been affected.
That text file listed items I would expect to see in Device Manager/View/Show hidden devices/Non-Plug and Play Drivers -
Have you checked for any yellow alerts in there ?
From your opening post, you have a number of devices plugged in - do you get the same error with those unplugged ?
-
Hi, I am enclosing the print screen shots in device manager.
I uninstalled mcafee site advisor as it is shown as the problematic device in the msinfo32.
the file shown was included in my txt file
ROOT\LEGACY_MFESAPSN\0000 device info path
If there is no hardware id, does it mean that it is not hardware, but software device by third parties.
I uninstalled mcafee site advisor, but still showing my pc name as unknown device
-
Hi, I am enclosing the third attachment also
-
Hi, Boggins
On a fluke, when i right click and note change hardware, the device was shown as not unknown device, but base system device and i could not capture. I give below the updated details. once it installed, the yellow mark has gone, but again came back immediately.
Intel R 82865g/pe/p/gv 82848 p processor to I/O memory interface 2576 Installed and ready to use
What this means? When i tried the same thing the next time, got the device as unknown device.
How to fix it? how to solve this
-
Intel R8285G is your Chipset driver.
For an OEM build, go to the computer vendor's support site and for a custom build, go to the motherboard support site and download the driver.
It may be listed as Processor to I/O Controller.
-
Hi, Would you please give me the exact link. If you want further details, let me know. Why this was not shown earlier.
Moreover, can i leave it as it is? Will it normallyl show as my computer name device?
-
To give you an exact link I would need to know the exact make & model number of computer if OEM build or the motherboard number if custom build.
Intel have an auto detect but that part of their support site is down at the moment with a 500 error, although you could try the Driver Update Utility.
https://downloadcenter.intel.com/download/24345/Intel-Driver-Update-Utility
NB - Your floods were mentioned on the late news last night with a picture of the flooding and citing 280 dead.
A lot of people in the n.w. England stretching to the n.e. England have had severe flooding through rising rivers because of Storm Desmond.
A month's rain had fallen in 24hrs.
Many homes damaged and loss of power but fortunately no loss of life.
-
Hi, I also tried that link, but it failed to find any driver in my computer.
Regarding the mother board specifications, is the text file not reflecting the correct details . The details are in the lower part of the text file, giving complete information.
It is an assembled set, and now recently i have changed my mother board and processor.
-
Hi, the link uplate details enclosed. No drivers found for your product was the message and I am enclosing the result
Is there any genuine driver update software, that could be used to find it automatically without any tool bars etc
-
The only thing I'd found earlier for yours is http://www.driverscape.com/download/intel(r)-82865g-pe-p-gv-82848p-processor-to-i-o-controller---2570 but as it's a 3rd party site and not Intel, I was wary of it.
I've tried all over Intel but it would seem R82865G/PE/P/GV82848P is no longer supported with no drivers being found and another page didn't apply to this one either.
Slimdrivers is a free driver updater program, but it would be looking for an update to what you have rather than a reinstall, but you could try it if the above doesn't work out - either way, create a restore point before downloading/installing any driver.
The left hand button is the freebie. http://www.driverupdate.net/
In the latest info Notepad you've posted, it has your Win 7 product key so you may want to edit that and repost.
I'm surprised you're using the Realtek AC97 audio driver as that tends to be for Vista and earlier Windows versions.
-
Hi, Thanks boggins,
Realtek ac 97 drivers were installed by the mechanic when i changed the processor and MObo. I can update from intel site, but they are non signed drivers and i am afraid that it may not work properly in other environments.
Regarding the intel.com they have a software , called software updater, but it seldom finds your product to update. It is a total failure on their site. But when you go to their site, a pop up comes to give feedback. Numerous feedback have been given, but seldom they response.useless site, with obsolete drivers and no support whatsoever.
I could very well download their drivers from their site, but it may work or may not. Can i update the drivers, when there is no problem with the existing driver for audio.
I will edit and then post the speccy. Thank you.
But i am surprised that it does not show up, when the computer boots up
-
How could i edit the txt file i posted. Please. can i ?
-
Save it as a Text file, go to Docs and edit before attaching.
I've removed your attachment so that you can modify your file and keep the same name.
If audio is working fine then there's no need to update the driver.
Have you tried Slimdrivers to see what that finds ?
-
Hi, Boggins tried that link. Ublock does not allow
-
Hi, I could access the site, but there is no download button. If i click the button it loads the same page of instruction.
-
Strange that, I've just tried the freebie button and Norton says it's safe - although I've seen something called something like Korad bundled with it, but SuperAntiSpyware removed it when I've used the program before.
I've just downloaded IObit's Driver Booster 3 to see if it's safe and other than unchecking the box to stop Advanced System Care being bundled, it installed fine but there were 3 tabs to close down afterwards :)
It has found 6 outdated ones for me including the Controller, but I won't be updating anything anytime soon until I feel I would benefit from them.
It pins itself to the Taskbar which you can unpin and its icon pops up in on the right side of the system tray to notify of outdated drivers - there's nothing listed in msconfig to show that it's running in the background or in services.msc - but you can change its notification if you don't want that popping up.
I've run SAS and other than Adware Tracking Cookies, it didn't find anything that could be malicious.
Anyway, if you want to try it - http://www.iobit.com/en/driver-booster.php

Hi, This is an update to the answer.
I said fluke to get the base device. No , it is not, it is by right clicking the unknown device and click scan for hardware changes tab, instead of right clicking the unknown device in the sub folder, which is the problematic device. The trouble shooter successfully installed the base device driver, but could not find the driver for the device listed in the sub folder.
I have removed all the devices , except keyboard and mouse. Still i have this problem
On extensive research, i found that the problematic device belongs to mcafee . I uninstalled all the product using their uninstaller. Still i find this entry in the device info path in the properties of the device manager in unknown device tab.
How to access the device info path. How to delete this unwanted mcafee device, which is a software but work as hard ware, strange behaviour.
-
You may have to check manually.
In Device Manager/View/Show hidden devices/Non-Plug and Play drivers there may be something remaining - Symantec puts a few things in mine for my Norton Security.
Check Program Files for any remaining folders and then go Start - type regedit - press enter - accept the UAC and navigate -
HKEY_LOCAL_MACHNE\SOFTWARE then scroll down the list for any folders and do the same in HKEY_CURRENT_USER\Software
Right click on any you find and select Delete, but as always, create a restore point before making any changes to the registry.
Close the registry sections back up and reboot to effect and then see if you still have the Unknown Device.
-
Hi, The problem is gone.
What i have done is to boot in safe mode and then uninstalled the unknown driver by right clicking. I checked the device and printers as well as device manager. There is no unknown device. I ran msinfo32 and then checked problem device and it shows nil.
Thanks boggin and quick responses. But still not known, how when i uninstalled and then boot, it does not load the driver i have uninstalled. Normally windows would again install those device drivers.[/i]
Then it must be a residue of the device driver path left by mcafee. How software drivers are shown as physical hardware device?
I will make it as solved. In the mean time, i also experienced very sluggish explorer, i ran chkdsk /r , but it did not find any big problems. Then when i checked the cpu it was 100 percent, i browsed the processes and found so many instances of jawaas.exe, repeating itself with minute precision. I do not know what to do. I immediately disabled and java and ultimately removed the java by revo uninstaller. Then the problem resolved. Why reputed company are doing mischief like this. The instance of the javaaw.exe are repleting itself,and i could see that in the process tab. Thank god. Is it java or some other crap ware doing hiding as java etc
-
It may not have been Java itself but some program running in the background that uses Java perhaps, unless it was the updater phoning home.
I have all updaters disabled in msconfig.
As for McAffee, it will have had its own drivers just as Norton does.
-
Hi,
thanks.
But how software device are shown as hardware device as in my case. Is it possible?
Or is it a way of intrusion by the software to gain access to user data by posing as hardware device How a program could download with its program a possible hard ware device and why it is done is still a mystery
-
My younger son initially used McAfee which came as a 30 day free trial on a new laptop and it never caused any problems for him, so can't answer why it should have caused problems for you.
It comes as a free trial on this laptop and it's the first thing I get rid of after a factory reset.
-
Hi, Please see this way. Unknown device if it clicked to trouble shoot, installed one driver , ie, the driver for some memory controller and failed on another. The problematic device was shown as mcafee , of which i only have mcafee site advisor program. I uninstalled site advisor thro their uninstaller, which when cleaned failed to clean the root legacy file. Indirectly, was it not, occupy the system base driver place when it is doing the job of site advisor and when it remains as such, acted as hardware driver.
When i uninstalled it using safe mode, it uninstalled totally and on reboot, does not show any yellow exclamation mark.
My question to you, is how a software driver, could be shown as hardware and shown as missing driver?
Now, this problem gone. Thanks again
-
When an AV program hasn't been fully uninstalled, it can conflict with the new AV program and cause anomalous problems, but as I've said, I've never seen where the computer has shown up as an Unknown Device before.
-
Hi, What about software drivers not device showing as hardware device?
