Corrupted OS files preventing boot after failed driver update

Q: Corrupted OS files preventing boot after failed driver update

I've been trying to get my computer back so that I can at least get some stuff on it I don't want lost for the past three days. I was updating an nvidia graphics driver and it froze. So I restarted my computer and things went down-hill from there.

Nothing I know to do (which is more than the average person) works. So most of (and perhaps all of) the quick fixes you all may suggest most likely have already been attempted at least once.

What I am experiencing now is a black screen with a gray bar on the top and bottom. The top is titled: Windows Boot Manager. This is written in the gray bar. The rest of the screen reads:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your windows installation disc and restart you computer.
2. Choose your language setting and then click "Next."
3. Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacture for assistance.

Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.

I am hoping someone can help me get make it so I can at least get some files off. System restore or anything like that is out of the picture because I was planning on getting an external hard drive for backing up, and haven't been able to yet. Ironically, payday is this Friday.

Anyway, I've even tried using ubuntu and also putting the HDD in another computer. Both ways it says that I can't get to it. When trying through the other computer, which has Windows xp, it says it's corrupt and cannot be used and what not.

How the heck can I repair the OS install (or whatever is corrupt) enough so I can get some stuff off before I do another clean install? Is it possible?! Please help!!

My friend helped me try to do an error-checking on through the xp computer. Did nothing. Would it work on a Win7 computer?

Preferred Solution: Corrupted OS files preventing boot after failed driver update

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Corrupted OS files preventing boot after failed driver update

Did you try the suggested startup repair options with the windows 7 dvd/repair disc?

It may take several runs and will at least attempt to repair the partition table.

If you tried that already , then use the commands instead of auto startup repair - usually does the job.

If you have the disc and want further advice, post back.

If you don't have a 7dvd/repair disc , get one from here - the same bit version as your installed o/s ( torrent, but it's usually quick ):

My Win2k system has started giving me an error that 'the file D:\winnt\system32\config\system.sav is missing or corrupted' when I try to boot. I never get to the desktop.

I've tried the Windows Installayion repair tool via booting from the CD, and it finishes doing its thing, but I still get the error.

Any idea on how I can fix this?

A:'corrupted' system.sav file preventing boot

system.sav is part of your registry, so it is pretty vital to your system, only thing i can say is copy system.sav from another computer and put it onto yours and hope it will boot enough to let you start backing up data and then do a re-install, because there are alot of settings and software specific settings in that file it isnt one you can just restore and go about your business.

Hi all.

I have an ASUS M-11 tower and I recently had it's Intel HD Graphics (4400) konk out on me. The HDMI output stopped working rendering my tower useless for watching HD movies on.

I tried using an Intel driver updating app but apparently it didn't work. After a reboot I get a solid red screen, with no text on it, and no way to interact with it. I can't login or do anything. The only thing that happens is the screen changes from red to blue if I tap ESC, that is it.

So I accessed the recovery options by pressing F9 at bootup. I chose the Reset PC option. It went thru the process, but after completing and its auto reboot, I just get a blank black screen now with no way to interact. No logos, no updating icons nothing to indicate more stuff is going on like setting up files. If I reboot from this screen, it just reboots the PC and loops back to the same blank black screen.

I tried leaving it for over 20 minutes on the black screen thinking maybe it's just doing stuff in the background, but nothing comes of it.

I am not sure what to do from here. I don't have a recovery USB or disc.

Anyone have another suggestion ?

I hope you can help me fix my dad's computer!! This site has helped me fix my laptop. I really appreciate you guys!!

On my dad's computer : I tried to update BIOS graphics driver per instructions for new larger monitor (which has not even been hooked up yet).

I went to the Dell website and entered the service code HPLW3G1 to find the graphics driver to update. I recall nvidia but now looking at the list that they have on that website, I am not sure what I downloaded. I saved it to desktop and then clicked to install it. I then got a small popup that said I must close all other applications. When I clicked ok on that little window - (so I could close the other applications that were open), it started installing anyway! I exited the install window (wrong thing to do? It said do not turn off power in red letters), closed applications. Then I restarted, because it didn't want to open google chrome.
NOW when I turn it on, the blue light on the on button lights up, sounds like the fan is running, but the monitor does not even respond, it goes into powersave mode. I tried another monitor, no change. The computer won't turn off, unless I hold the off button down for awhile. The wierd thing is that when the computer is unplugged, it comes back on when plugged in again. But there is never any flashing lights below the on button that indicates that the hard drive is working. I think this may be bad? I tried hitting F8 after turning it on, and nothing happens.

I had a (known) problem affecting the use of Enterprise Wifi networks. Long story short, the solution is to downgrade drivers to a lower OS level. I manually installed Vista drivers for my WiFi, problem solved.

Enter Win8 x64 automatic driver updates. After reboot or after some time, my Vista driver is automagicallly replaced with the default driver for my card (Atheros AR 9285), and my connection can no longer be authenticated and is dropped.

I tried disabling automatic driver search through windows update, but the newer driver is already bundled on my system. Thus the new driver is still installed. I can't easily delete the driver, as the filenames in c:\windows\system32\drivers are the same for both versions and they overwrite each other; I don't know where the newer copy is stored as well, a copy of it must live in some additional path as well, as does some inf file that comes with Win8.

Does anyone know of a way to lock a particular driver version in place? I don't mind automatic driver updates in general, but I'd like Win8 not to touch my WiFi drivers, at least not until the root cause in the latest drivers has been fixed.

Hello. First post. I have a problem that I not sure how to proceed. I still have a Windows XP 32-bit computer, for whatever reason it was still at SP2. Everything was good.

Last Friday afternoon (10/16) I decided to update it to SP3. I was logged in as a "power user", with I believed administrator group rights. I downloaded the big SP3 file: WindowsXP-KB936929-SP3-x86-ENU.exe. I executed the update and it stopped on a file "pchsvc.dll", it said the file size was wrong and the update aborted. I read this type of error might be due to insufficient privileges. I had to do other things and let the computer sit for 2 days.

I tried to install SP3 again on Sunday afternoon (10/18). This time logged in as true "administrator" account. SP3 still failed and the computer rebooted. I logged back in as administrator and realized windows was not working correctly. Here are the problems that I have now:

Most programs fail to execute, even simple programs. They fail with errors like "insufficient resources", or "application failed to initialize properly."

I tried to run "sfc /scannow" to see if it could correct the failed SP3 install. I have a SP2 install disc, but SFC wants a different disc and fails on multiple files.

On simple file copies I get a popup balloon that reads: "The file or directory $C:\Secure is corrupt or unreadable. Please run the chkdsk utility". I tried running chkds... Read more

Welcome to the forum. You need to run the chkdsk c: /f it will say disk locked test on start say yes. there are two separate things a faulty hard drive is the drive its self faulty but a corrupt file system is a windows fault meaning the HD is ok but chkdsk need to sort out corrupt files.

For an unknown reason (my guess is an update was automatically applied and automatically restarted), my computer rebooted overnight and in the morning was stuck in a failed boot loop.  When trying to boot I get the message:
"Preparing to configure windows"

"Do not turn off your computer"
Then after a few seconds the computer reboots and does the same thing.  Safe mode yields the same result.  Using the F8 option to restore last known good configuration doesn't change anything.  I can boot into the recovery console.
I have tried running SFC /SCANNOW in a command prompt in the recovery console and get the message:
"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."
Restarting of course doesn't change anything.  So it seems something happened to an unfinished update and is still pending.  I think if I can remove this pending update I might be able to boot normally, or at least run SFC and hopefully then boot
Does anyone know what I should try to remove this pending update that appears to be preventing a successful boot?

I installed the latest round of Windows updates for my Win7 x64 install and it never completed (ran for about 24 hours) so I powered off the machine. Upon restarting, it said:

"Windows failed to start. A recent hardware or software change might be the cause" and has instructions for using system repair, then at the bottom:

File: \Boot\BCD
Status: Oxc000000f
Info: An error occurred while attempting to read the boot configuration data
So I booted off a Windows recovery disk and figured Startup Repair would fix it. Alas, after it says "Windows found problems with your computer's startup options" and asks me if I want to repair, I click "repair and restart" and it says "Failed to save startup options".

The "repair details" are:
Name: {bootmgr}

I've tried running Startup Repair from the manual options screen and it says it cannot repair automatically. I have two partitions, the 100MB windows System partition, which Recovery Console mounts as C:\ and my main windows partition, which it mounts as D: and I can see all of my files on it.

I tried to update my older Radeon ATI 5450 GPU via windows update...

I received the message from windows update, and showed it failed update with the 0x800706be

However when I go to device manager and check the details of the installed driver it clearly shows the new updated version? So I wonder which is correct the device manager showing the new version of the driver or windows update?

A:Failed Update 0x800706be driver...but device mgr shows updated driver?

You can identify the problem using Device Manager, which you can access by:
Opening the Control Panel Window
Selecting and double-clicking System
Clicking Device Manager
In Device Manager check if there is an exclamation point, a yellow triangle, or a question mark against your Dell device. If there is, there is a problem with your Dell device.

I currently have this problem in regard to the Bluetooth in my Lenovo P70.  There is already a forum topic on this issue at https://forums.lenovo.com/t5/foruams/v3_1/forumtopicpage/board-id/tp07_en/page/1/thread-id/71644.  If you want to respond to that particular problem (It is still unresolved) please do so there.  The pupose of this topic is the more general question of what do you do when a Lenovo-supplied driver update is faulty, especially when you are out of warranty.  (That question has not been answered in the other topic.) Bluetooth was not working on my computer when I went to use it.  The obvious thing to do was to get the latest driver, which I did.  It is n1dww15w.exe.  The driver did not work right in at least 2 ways. 1.

Had a BSOD problem the other day and I posted to the forum:
2 separate atikm?ag BSOD errors

As part of the solution I was encouraged to download and install the latest graphics driver. Unfortunately, that driver install somehow messed up my USB Controllers - every device listed (and there's 7 of them) display a little yellow triangle with an exclamation point. Right-clicking on any of those 7 items gives me the following.

And the 2 TB external HDD (which I depend on mightily) is, right now, useless on this machine.

Update - I've now followed the steps in this tutorial USB Driver - General Fix for Problems and not only did it not fix my USB problem, but I've now lost my network printer. Sigh...

A:USB Ports Corrupted After Graphics Driver Update

Ok. First of all...

1. Go to the HP website and download the proper graphics drivers, the chipset drivers, and the USB drivers (may be in the chipset drivers) for your laptop.
2. Uninstall the graphics driver you currently have installed.
3. Reinstall the chipset drivers.
4. Reinstall the USB drivers.
5. Reinstall the proper HP graphics drivers.
6. Reboot

That will hopefully clear up the problem.

The problem that you are having stems from the fact that the generic graphic drivers that you get from the AMD website are not made for your HP laptop. These drivers also (usually) include a USB driver, that is (guess what?) probably incompatible with your hardware as well, and that is what has borked your USB ports.

Try those things and please post back any success or failures so we can help more.

Hey guys,

The problem is when i click/drag my mouse on my desktop, my background turns black, also when I move icons - I realize this is probably just a driver issue, or corrupted system files, but I am worried about my computers health.

These are my PC specs.

Didn't see if it said in there, but I have a Single Strix 970 with the latest driver.

Upon googling this problem which I described in the first paragraph I wrote, it took me to this article. Here ----> https://support.microsoft.com/en-us/kb/929833

I ran the test, as stated, sfc /scannow

This was the result -->

As you can see, it says Windows Resource Protection found corrupt files but was unable to fix some of them, details in the CBS.log etc etc.

Here is the Log. - I had to copy/paste info from log, put it in a .txt file in order to upload it, it was way too huge to put in text in the body of this post i believe.

Anyway, what is bothering me about this is the overall health of my PC, being that it says there are unfixable corrupted system files.

Any help is appreciated, thanks.

My computer was installing the latest updates for windows 7 professional 64 bit and the battery died durring the shut down process, and now when I start the computer it will allow me to log in but when it hits the desktop it freezes up completely.

I have tried using the system restore but somehow my restore points cant be found anywhere and when I tried using the system repair option on the installation cd it says it cant because the problem is unfixable. The error it says it has is in the boot sector and it says the error code is 0x45d, but when I ran it a second time it didnt say that.

I really dont want to deal with pulling off all of my personal files and then installing a fresh copy of windows because that would be too much of a hassle, but if i have to i will.

Title pretty much sums it up. Recently built myself a new PC, did the usual XP installation, anti-virus, etc. Was performing routine updates when I started to try to install the update for the video card. Basically, it wigged out, changed the resolution of my screen and froze up during the setup. When I ended the task, I had a few warnings telling me system files got corrupted, such as the chkdsk.exe file.

I'm pretty pissed, needless to say, after spending much time building the PC and setting it up only to be undone by a routine video card update. Anyone else experience this problem? I tried rebooting, and now my monitor won't recognize the hook-up. Thinking about putting in the XP disk and running repair on it. That should do the trick, right? Either that or reinstalling XP for the THIRD time.

I tried to backtrack and install the drivers that came on the CD, but couldn't uninstall the old drivers first since half the stuff in my Control Panels was missing! (Including Add & Remove Software). So that's when I rebooted and it went to hell.

Maybe install BIOS update and mobo drivers first, if any? Does the sequence matter?

Motherboard: eVGA nForce 680i SLi
Video: NVIDIA GeForce 7600 GT (2)

A:Vid Card Update Corrupted System Files!

Okay, I ran the repair on XP and it seemed to work, now that I'm back on and posting on this forum using the computer. I took a look at my video card drivers on the device manager and found that my 2 video cards have different drivers (looks like one's older than the other).

Is there a driver installation issue with SLi? Looks like I wasn't able to install the most recent video drivers for BOTH video card, only one. I'm guessing this is what messed my computer up in the first place. I'm thinking of removing the drivers completely and starting fresh with the drivers on the CD that came with the card.

Any suggestions?

About half a year ago, give or take, I ordered a Windows 8 OEM disk to install on my laptop. Machine runs fine, even upgrading to the 8.1 Preview and eventually to 8.1, and dual-booting Ubuntu GNOME. Life is good.

The most recent system update, however, continuously fails for some reason, giving me no error messages.
I've tried running sfc /scannow and DISM commands, but both of those fail, saying that there are corrupted system files preventing them from working.

The normal way to fix corrupted system files with Windows 8 would be to Refresh. However, I can't refresh with my install disk because it's not an 8.1 disk. I've tried using the trick with creating a useable ISO file, but that trick fails because the Product Key I'm using is a developer's license, not retail.

Any more ideas without starting from scratch? Thanks in advance.

Hi there,
just recently I have dowloaded a program (unfortunatley I have forgotten this) off a unknown site. Just after this my computer began to run extremely slow and both my browsers (Firefox and IE) were not working also my computer would not shut down; it would get to the point where it says windows is shutting down (on the blue screen) and just freeze, I would have to hold down the power button to switch off. At the time I was Using Norton as my AV and it did jack-all. I then removed Norton and replaced it with AVG 8.0. Unfortunatley AVG would not update (i'm guessing a virus was blocking it from updating?) so i had to do a directory update which was successful. Then after installing Spybot Search & Destroy both Spybot and AVG managed to remove a whole lot of trojans and malware. Now my computer will successfully shutdown and both my browsers began to work (although not 100%). After many repeated scans every day AVG and Spybot pick up trojans (which never seem to go away); "Virtuemonde" and "Win32.BHO.df" always show up and will not successfully be removed (and yes i have tried to scan and remove with internet disabled). Also if I goto My Computer and double click C: drive (local disk) it says:
Windows cannot find 'resycled\boot.com'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then clic... Read more

Hi. I will try to get this in simple as I can.

can I slave this drive & put the install disk in the cp & copy the boot sector
from the disk to the slaved vista home prem program?
What copy command? dos dummy...
I have already slaved the drive & I deleted the corrupt boot files, right or wrong I did it.
My Vista install disks do NOT have repair on them.
I have downloaded numerous "Repair disks" & they will not boot. Only thing I could get to boot was
a win7 repair disk as I understand that vista & win7 have somewhat interchangeable bits & bytes.
I have run bootrec.exe to no avail & chkdsk/f and a few others.
This drive has a lot of stuff on it & don't really want to start over.
below is probably why I cannot edit the boot sector files..

I recently suffered an apparent corruption of my primary SATA hd that caused me to be unable to boot into regular or safe mode. This drive was running my XP Media Center edition. I have data I need on this drive so I grabbed the only OS disc I had available (Vista Home Premium) and installed it on a secondary IDE drive that was already in the machine. I was hoping to be able to get to the drive through Vista and rescue the files I need then do a clean install on the SATA drive. The problem is, any time I even attach this drive my system fails to boot. The system just hangs on a black screen at startup. Is it possible for a drive to be so corrupted that it will not allow a system to boot FROM A SEPARATE HARD DRIVE?

System specs:
Dell XPS 400 2.8 GHz dual core CPU 3 GB RAM one 80 GB SATA drive and one 250 GB IDE HD
(originally) XP Media Center Edition on 80 GB SATA HD
(after problem) Vista Home Premium on the 250 GB IDE HD

I also installed Windows 7 RC on the other partition of the IDE because I hate Vista (that should be irrelevant to this problem though, I think)

edit: Also, I tried a Ctrl + F11 system restore on the SATA drive at one point but received an error that I interpreted as meaning the drive was corrupted... or something to that effect

Hi there,

as of a stupid faulty LAN-driver by Intel/Sony, I got horrible problems with BSOD's and graphics failures and due to my stupid unsystematic approach it took me a while to fix it. (Simply: Installing newest ethernet drivers after I found out they were responsible.)

As of now, my system (Win 7 Pro x64) is a total wreck, can't open either my explorer or my substitute program (Directory Opus), opening the context menu crashes the explorer.exe and often I just can't (left-)click on something. Problems uninstalling and installing stuff also.

Now, how do I again start & proceed with the Windows repair without losing any data or having to reformat?
(The awful European Sony support was no help at any time...)

If you're curious to further investigate into my issue I attach you the log file that "sfc /scannow" (download here (10,1 MB)) brought as well as the log file of my failed installation try of avast virusscan. (No I don't have a virus/malware, checked for that at least!) Funny enough in safe mode everything works, this is also where I installed avast then.

Should I run any other scans in your opinion? I think I'd just should repair it.

Thanks in advance!

Kind regards

PS: I hope/assume you don't consider this issue for the BSOD forum, as I already fixed it. But of course you're free to move it!

I've been lurking on these forums for a couple days now, looking for a solution for my trouble with update failures and constant program crashes. I had to completely format my hard drive about two months ago and bought an external hard drive to accommodate just such an event, so doing it again is irritating but on the table.

I used an elevated command prompt -> sfc /scannow to look for and attempt to repair corrupted system files in the hoeps that I won't have to (once again) refresh my system. However, it could not repair all the corrupted files, and I do not have a Windows 7 installation disk as the backup is included on a separate drive on the computer itself (ask Toshiba, they're clearly nuts).

I would appreciate someone with greater Windows chops than I taking a look at the sfc.txt file from the CBS log (which I somehow am denied access to, even as Admin?) and any input on fixes for my situation other than pushing the Big Red Button of Mass Destruction on my hard drive for a second time.

A:Update Failure and Corrupted Files - SFC text included

If you do not have a Windows 7 installation DVD, you can download a legal copy with SP1 integrated from here:

Windows 7 Direct Download Links

Make sure you get the same version you have, Home Premium, Pro or Ultimate and 32 or 64 bit. Note that Basic or Starter is not available.

I recommend using ImgBurn at 4X speed (or the slowest available) to create the DVD from the downloaded .iso file.

You can do this on any computer capable of burning a DVD.

YOU MUST HAVE A VALID KEY TO INSTALL THIS .ISO. The one on the COA sticker on your computer will work.

You can also create a bootable USB Flash drive (4GB or larger) to install Windows 7 from.
Download and run Universal USB Installer – Easy as 1 2 3
Select Windows 7 from the first drop down list, all the way to the bottom
Select the downloaded Windows 7 iso file
Select your USB flash drive
Click Create

For techies or folks who work on computers: Create Windows 7 Universal ISO With All Editions Selection On Install with ei.cfg Removal Utility.
This will fit on a 6GB flash drive or can be burned to a DVD.

The road to this point is long, so instead of telling you every step along the way, I'll give you the milestones that have led me to my dead end.

Back in Sept, for reasons not relevent, I added two MS Chineese languages to my system via the Update program. After discovering them not any use to my work, I uninstalled both via the Programs and Features app in the Control Panel. Since then, I can't remember if it was before or after I uninstalled them, I have been having problems with about 6 updates getting Error Code 80070490. It basically means that the CBS Manifest file is corrupt. Actually the CBS Manifest file identifies some other files that are 'corrupt'. I don't believe the CBS Manifest file is corrupt itself as everything else I've done to this point has determined it to be okay. I have done everything the Windows Help & Support and subsequent instructions and have not been able to repair the problem. Although, it has helped me to somewhat determine where the problem might lie.

I have been doing a periodic update of the system drivers on the laptop.  Last time I can recall doing this was nearly 2 years ago.  And this time I encountered problems. This topic is a follow-up to my query on this thread, regarding safe mode start/restoring after a failed driver update:http://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/booting-safe-mode-on-hp-g6-2002au/m-p/5690028/... And as i reported there I begam doing a one by one update to locate what caused the original problem with the bulk update.  After 7 one-by-one driver updates, I found the (or, at least) one causing the problem.  In the following image, the 2 PCI-to-USB host drivers caused a windows failure message after the update.  There are 6 USB-related drivers in this extremely old/aged list and clearly they relate to the number of installed hardware items on the laptop.  See this screen shot of the Device Manager list:  Of the 6 USB drivers to be updated, I picked these 2 items to update first because 1) they looked to be the oldest (the replacements were dated in 2010), and 2) as I understand the technology, these bits connect the processor bus to the actual host and hub chips. I chose only these 2 PCI- drivers for update (unticked the selection boxes for all the others in the booster list), and proceeded.  When the install was completed a windows message box reported a windows failure for one of the devices (which one, not stated or ev...

Not sure if this is the right place to post this as it may be a hardware issue but as XP is the OS I thought it would be a good place to start.

I have an XP SP3 machine that was not booting correctly. At power on I would get a message saying "Windows could not start because the following file is missing or corrupt..." The file name would quite often be different.

I used the recovery option from the CDs supplied with the machine and this appeared to work for a while but then the problem resurfaced.
I tried a fresh install of XP SP3 from the OEM OS disc with the same results.
We then purchased a new hard drive and installed the OS with the same results.

It's quite an old machine so I'm wondering if there may be some other hardware-related issue that I'm not picking up on.

Any help appreciated.

Here's the situation...

1) Computer was running very slowly. I re-booted, thinking that might help.

2) Since that time, it won't boot Windows. I just see the Dell symbol on startup (it's a 1.5 year old XPS 8900 with no serious prior problems) and then it goes to a new screen and says it doesn't have a bootable drive.

3) So...I ran diagnostics (both on my own, and then a Dell tech told me to do the same things). It's supposedly not a hardware problem. Instead, Windows 10 is the issue. So I had them overnight me an installation disk (it came pre-installed, so I didn't have the CD before).

4) It's VERY important to me to save my files if possible. Some are for work, some are family photos...some are backed up, but some from the last couple months are not (I just haven't been diligent enough about that). The computer has two internal drives...1 TB main drive with Windows AND some valuable files on it...and another 2 TB drive which is a backup and where I store most of my photos (my side job is photography so I generate a ton of files every year). I would really love to recover both if possible.

5) Called Dell again tonight after I got the installation disk in the mail, and the tech unfortunately didn't really know what he was doing...after just one failed attempt to reset the computer WITHOUT losing files, he immediately wanted to give up and click the "scorched earth" (delete everything) option. I talked him out of that, and he said the other op... Read more

So I've been trying to update my graphics card. Before I ever got the notification for the update and tried to install it, I could play minecraft, and star craft, and watch Netflix video.

Since, I've gone to my manufacturers website and re-installed my driver, but I think the real problem is seeing how I cant connect it. It always says it failed due to the I/O error, so I cant connect it to the video card or something.

I have been having trouble with Mass Effect Andromeda and minor freezing during gameplay. Nothing really major, just annoying pauses in the flow of the graphics and all even in low despite using 2 AMD 390X cards, a Ryzen 7 1700X, and a MSI gaming pro carbon motherboard.

I thought I could fix it with a driver update, but not only did the update fail to go through, now anything that loads causes my computer to freeze. It froze for 10 minutes until all of my software finished booting during the startup, and another 10 minutes while trying to login to Origin.

I have no idea what is going on, and I don't know where to begin to fix it. Please don't ask for a DXdiag because it's impossible to operate this thing right now. Just know I'm running on the 17.4.4 ReLive driver, and for some reason, my computer failed to sucessfully install the 17.7.2 update.

This problem happened before when I tried to install the 17.6.6 version as well, but I was able to fix it by rolling back the driver. I can't now, so now I don't know what to do. Any help ASAP would be great.

I can live with that since I don't tinker with them that much, but I would still really like to know what the F*#%tapuss is going on with my computer.

Hi GhostRaider, welcome to the forums.

You might want to try going Here and try running Intel's 'Driver Update Utility' and see if that gets a better result than Windows Update.

I had the same issue when first install Windows 7 with my Intel 945 Express Chipset, the update would fail every single time

Unfortunately, Intel have not yet released a Windows 7 (32/64) driver for the 910GML or 915GM so Vista drivers in compatability mode may be your best bet of the 'Utility' does not work.

Brand new X1 Carbon, 6th Generation. I used the lenovo Vantage software to update the system. It installed a new driver for the LTE Cellular modem (Fibocom L850-GL). Ever since, the modem no longer shows up in the Network areas of Windows.  Device Manager shows the WWAN under "System Devices" but not under "Network Adapters". The device tries to "install/de-install" all the time. Those windows install/de-install chimes keep coming, about every 2-3 minutes. Has anyone else had a problem since the update? I went as far as re-loading Windows (using the internal utility), but it actually doesn't delete the new driver files! Wiped out all user data, etc., but the new driver (along with old driver) are still there. Selecting the old driver doesn't help.  Either the device has failed, or I need to wipeout the new driver and assorted files (85MB) and re-install the older driver which worked. Any help here?

I'm going to start this out with an apology, because I am not super technical and don't have a very good understanding of what happened.
I bought a hp laptop a year ago loaded with Windows 8.  A few weeks ago I kept getting a pop up to update to Windows 8.1.  I didn't want to deal with it and kept choosing the "postpone" reply.  I didn't pay a lot of attention to this, but I believe that it had a "countdown", and a few days ago I was busy doing something else and it automatically counted down and started updating to 8.1.  It went through the process, and when it was done, it rebooted and asked for my password.  This is when I realized that I have no idea what my PW is, since I had always used the fingerprint.    
After several wrong password guesses, it then automatically reverted to a previous version of windows, and now none of my files are accessible and anything that I do in the current session will not be saved.
I could kick myself for my idiocy, but there it is.  Are you guys familiar with this, and can anyone advise what my next steps should be to recover my files (some of which are not backed up)?   Thanks in advance.

I rebooted my computer, and it said something about turning off wrong, and gave me options to either boot into safe mode, restart normally, or restart at the time that worked normally. All of them lead to the same error mesage with the blue screen.

I did a little research on this error, and found a microsoft help page about it: http://support.microsoft.com/kb/307545
Instead of using the recovery console from the CD, I used my computer's recovery console (everytime I reboot, it gives me an option to go into the recovery console or continue normally, so I entered that recovery console, thinking it was the same as the CD's recovery console...)
