How To Fix Unknown Drivers
Nov 11, 2009
I have installed windows 7 ultimate in HP dv5-1126em. My previous version was vista home which came with inbuilt.Windows 7 already installed all necessary drivers at the time of install the OS and I manually installed VGA only. But when I checked my device manager there is showing 5 unknown drivers. There are 3 system base driver and 2 unknown. I tried many ways like driver max, Everest....etc for search drivers but I can't do that. Can anyone tell me, how can it fix? Please give me some instruction.

When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.
Ghost Shot> This was about a week ago my Windows 7 started acting up right before the big patch Tuesday. I've been running it for over a year now and it's been solid. When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing restores from Ghost 15,etc. Anyway, ghost was backing up my system C: drive before last week. I have yet to even try and use Ghost to see if it would successfully restore my OS but I've been using it to backup my C: drive anyways. Prior to last week it could backup my C: drive fine. I might try a Ghost restore point from a few weeks back before this happened but not sure yet[CODE]

My computer is running standard Windows 7 Home Edition (64 bit) and I have been having some problems with it recently.1. Windows Explorer crashes when I try to access files from My Documents, My Music etc. This only seems to be when I access them from the start menu. If I go via My Computer > Users etc all is fine.2. After a short period of gaming, the computer freezes and starts running unbelievably slowly. It is unable to create textures on games and all I can see is characters on a blue screen. I have tried this on Fifa 11 (which now does not run at all), Deus Ex: Human Revolution, and Counterstrike: Source. It seems to be fine with browsing and low-end programs though, so I can listen to music and use the internet all fine. All of the games are legally bought etc and worked fine. I left my computer for a few months while away and nothing has changed on it apart from a few windows updates.

I got a new Dell Studio XPS 13 laptop a week or so back, loaded Windows 7 RC and everything worked fine after a bit of fettling here and there. On Tuesday or Wednesday I had a problem where the laptop locked up while using a Logitech USB Radio mouse. Thinking the mouse caused the lockup, I disconnected it and have been using the touch pad since and no lockups. So far so good.
Then today I plugged in a set of Logitech USB headphones for Skype and I got an 'unknown device' error. I tried with other USB items, ADSL modem, memory stick, all had the same problem on both USB ports and nothing I did would solve the problem. Much googling and a search of this forum again came up with nothing I could use.
I then had a flash of brilliance - I figured it must have been the mouse that started the problem when the laptop froze and somehow something was blocking the USB useage. I plugged in the mouse whereupon it loaded up the software and worked fine, and now everything else loads up and works OK too!
I can't explain it, I'm just a programmer and don't really understand computers but if it helps anyone else in the same frustrating situation, there it is.

I have Avast! Free Antivirus installed on my Windows 7 Ultimate 32bit. Unfortunately this antivirus mistakenly sees a program as a virus and moves the file to its virus chest. There is a restore function for me to use that program again. Doing this some unknown files appear and I tried to delete it but some won't. Here is a screenshot.

i was in my downloads folder on my laptop, and noticed a file I hadn't seen before, it was a zip file and when I opened it, it contained Psd. documents that i had created literally years ago, and never opened since. the strange thing is that in properties, it tells me that the zipfile, and files within the zip, were last created and modified on the 15th oct 2012. which would be ten days ago. also i says that the time which i it was created was 9:30am. i know that my computer is never on that early in the morning So, my question is, does/can windows create a folder of its own accord? is this a case of ghosts in the machine?

I get an alert from my firewall defense that 'Systed could not be recognized and it is about to create a new file/folder C:WindowsSystem32LogfilesWMIRtBackupEtwRtmsMpPsSession7.etl' and it goes on to say this happens when a new application or update is installed. I updated windows a few days ago and reinstalled the whole windows. I blocked it a few times but did a google search and the folder seems somewhat genuine windows folder but this particular file is not explained. Should I allow it? I have allowed it a couple times.

After transferring some HPFS USB drives from my old PC to the new PC, I've ended up with an unknown user in many of my files. It will be OldPC/Steve, but it manifests itself as S-1-5-21-713417444-3787200217-3968111754-1006 as demonstrated by cacls:
E:>cacls tracefinal.txt /s
E: racefinal.txt "DA;;FA;;;BA)(A;;FA;;;SY)(A;;FA;;;S-1-5-21-713417444-3787200217-3968111754-1006)(A;;0x1200a9;;;BU)"
I can write a script to display the SDDL string for all my files, and to replace the SDDL string with the unknown user excluded, and leave it running for a few weeks (there are millions of files)?

This unknown "Local Disk Q" just showed up this morning, and my regular external drive was gone. I reconnected my external to another port, and that went fine, but this locall disk q remains, and can not be accessed, changed, removed, etc. I scanned for virus's, and all seems ok. How can I remove this, and where did it come from?

I purchased a mouse keyboard combo that works as long as the computer is awake but when the computer sleeps the device will not wake up the computer. I believe it is because it its registered as an unknown device.

My son has a problem on his PC where everytime he starts up his computer or reboots he can't connect to the internet and the little network icon in the corner of the screen has a yellow warning sign. If you disable the network adapter and then re-enable it then the problem goes away.

I have 2 PC's setup with windows 7 x64 7600, one is my main PC and the other is my HTPC.
My HTPC is opening up UDP port 54838 via UPnP on startup, with out any applications starting.
This is a fresh install with no software other than iMon which is for the remote and VFD.
I have run tcpview and currport to see what is doing this, but they only show that the port is open and not what is associated with it. Have also run Sysinternals Autoruns, which lists everything that is running as a service or as a program, and I can see nothing suspicious !
I also have downloaded a free version of UPnP Explorer, but this only displays info on the physical router side of things.
I have searched the net and can find no mention of UDP port 54838 anywhere whatsoever, and have checked all of the port listing sites and none of them have any details of this port number, other than it is in the dynamic private range ... so it could be anything
I have tried to create a firewall rule to block it, but UPnP just creates another rule to enable it !
I know that the simple answer is to turn off UPnP, but I do actually use it for quite a few applications and devices so it would be a pain to do so as UPnP works really well with multiple devices that switch from wired to wireless mode and with dynamic IP's.
Has anyone got any ideas on a) what this port might be and b) if not, what else I can do to track it down ?
I don't want to get paranoid about it but I am security conscious enough to want to know what is making connections outside of my network with out my permission.

New Machine, new HDD, new Win7Ult install...
Windows Update is failing for some reason (I was successfully able to install 2 updates, but all of the others fail)
I am getting an "unknown error" 80070308, and while there seems to be one other reference to this on a MSFT forum, the solutions there were basically restart the update service, which doesn't work, or rename some of the Windows files... which I did as well to no avail.
Does anyone know what this error is? Or had it before?
