Windows 7 Stuck In Safe-mode Loop CLASSPNP.sys
Oct 19, 2012
I went into msconfig on the work laptop and changed the boot to safe boot network, as soon as I went to boot up the laptop and get into safe mode, the laptop freezes at CLASSPNP.sys then I have to reboot.I need to get it to boot back into windows normally, but even selecting "Start windows normally" sends it to safe mode because I set it to boot there in msconfig. What can I possibly do? I've tried running start up repair but says it cannot repair the issue. Due to security, the laptop hard drive has been encrypted with truecrypt, and therefore when I put the OS DVD in to try and do something from the command prompt, there are no OS's listed as installed so cannot alter the bootmbr or any windows files.

My Windows 7 ultimate x64 is rebooting itself at the welcome/logon screen, in safe mode only. Normal mode is fine. The reboot happens instantly, after a few seconds at the welcome screen, the screen goes black and the system is rebooted as though I had hit the "reboot" button on the case, with no clean shutdown taking place. I am at a loss to know what could be starting in safe mode, that _doesn't_ start in normal mode, to cause this.
I have recently done a repair install of windows (the problem was there before that), I have tried replacing the safe mode parts of the registry with clean ones downloaded from an AV vendor website (mcafee if I remember correctly), and have tried doing sfc /scannow which resulted in a corrupted boot.sdi being replaced with the archived copy. None of these have fixed the problem.
Obviously, given that I have a usable normal mode, and good backups, this isn't the biggest problem ever, but it would be nice to get it fixed especially for the next time I need to fix a dodgy driver install or similar. What I can check next, particularly in regards to understanding the startup process and what will be loading at the welcome screen that might be causing the reboot.

I have windows 7 home premium 32 bit dell laptop. Lately, it takes more than 10 minutes before it boots before the windows logo appears). From there the computer works normally. I got a suggestion to check for malwares or viruses so that is what I did. I started by going to msconfig and edited the boot options to start automatically to safe mode with networking, then rebooted my system. After booting, it loaded up the initial screen of safe mode, but then it restarted by itself.
I am now stuck on this reboot loop going into safe mode, it won't even let me go back to normal mode. I went to startup repair, but it didn't find anything, so had to reboot again onto the same situation. I have searched for possible answers, and the best that I could get was to remove the safe boot options and go back to normal mode. The syntax to type was bcdedit /deletevalue {default} safe boot but it didn't work, same with bcdedit /deletevalue safe boot.
I am getting this : "An error occurred while attempting to delete the specified data element. Element not found."

My system is stuck in a boot loop while booting in safe mode,I was updating the drivers on my video card. I used driver cleaner pro to remove my old drivers. I then used msconfig to boot in safe mode with the minimal option selected. When the computer reboots I get to the screen to type in my password for 5 seconds an the computer reboots itself.

i just bought an asus u31s laptop a couple of weeks ago for school and all was great until today. it suddenly crashed and gave bsod. i was just on Internet or something, nothing special, but it had been running for a few hours. so now it won't boot up, it simply reboots constantly. i can't even get into safe mode. bios i can get into, but i'm unable to do anything, since it appears to freeze, when i get in there.

the only way I can accurately portray my predicament is via numbered flow chart:
1. Wake up sleeping computer, nothing happens, starts humming faster and faster, so I pull the plug.
2. Turn on computer, goes through the ASUS screen, then the mother board screen has some weird pixelation on the left scree, like some lines or something. Windows is loading....then black screen forever. do this 1 or 2 more times.
3. Go to System Repair and System Restore. Repair fails and tells me a Boot Driver is failing. Restore fails each time.
4. Hold F1, go to boot menu, hit F8, select Safe Mode. Safe Mode works, fantastic.
5. Do AVG Defrag, Disk Clean, and Disk Repair. Then restart...now I get a blue "Dumping Physical Memory" screen.
6. Go back to Safe Mode, use boot disk, tell it to un/re-install windows.
7. Come back later and find it in Phys Mem dump loop, pop it into Safe Mode again. I then see two Windows 7 OSs to choose from, pick the bottom one. Says it can't complete installation in Safe Mode, restart it normal, Phys Dump loop.
8. I do the same thing for the top Win 7 choice, same thing.
9. I've back up all my files, and have drivers/boots disks for everything I own. How do I wipe my hard drive and start fresh?

The problem is that when I boot my PC it will go black and restart after getting to the windows logo boot part. If I try Safe mode it will get to SYSTEM32DRIVERSDISK.SYS and then just bluescreens and restarts again.Before it got to CLASSPNP.SYS but I tried to rename it to CLASSPNP.OLD and now it didn't really change much. I also tried using this code but it just tells me that some files are corrupt and it cannot repair it.If I try the automatic repair option it will just try and repair for a couple of hours and then say it cannot repair and rebooting the PC.

So I was using a program called TuneUp Utilities, and I used this function called the Disk Doctor to check for errors in my computer.While it was checking for errors, my computer shut down automatically and when I started it up again a black screen appears giving me the option to either load Startup Repair or Start Windows Normally. When I start Windows Normally, everything goes fine until I see the cursor. Nothing happens and then the computer restarts on it's own. I've even tried disabling restart on system failure but when I did that the computer just stayed at a dark screen until I restarted it.When I load Startup Repair, it searches for problems for like 5 minutes and then says it can't be automatically fixed. It says to remove all USB cables and everything (which I did but had no effect) and lets me have advanced recovery options.When I load advanced recovery options, all that appears is Startup Repair again.When I press F8 and do a Safe Mode, it starts up normally but once I see the mouse cursor the computer restarts.

When I start my computer everything seems to be working fine but after login it says Please Wait then freezes at Welcome screen and the cursor can be moved around the screen and shows the loading icon and the screen also flashes black every few seconds. I've restarted and attempted to access Safe Mode however it also freezes at Welcome screen. I went into the repair system screen and tried a system restore but it says there are no restore points available and I know I haven't deleted my restore points. I've tried disconnecting any of the hardware I've had installed but that hasn't helped either. There also isn't any faulty hardware. When it was last working it said there was a Windows update so I installed the update but when I tried to turn on the computer the next time thats when the problem started and I don't remember what the update was for. I upgraded from Windows Vista Home Basic 32-bit to Windows 7 Home Premium 32-bit about 2 months ago and up until now I've had no problems with it. What can I do?
Here are the system specs:
Dell Inspiron 530s
Intel Celeron 2.00 Ghz
3.00 GB DDR2 RAM (I added 2.00 gigs myself came with 1.00 gig from factory)
Windows 7 32-bit upgrade from Windows Vista Home Basic 32-bit
250 Gb Hard Drive

my Dell Studio 1555 laptop will not boot either into regular windows or safe mode.When booting into safe mode, the very last file that will load is "CLASSPNP.SYS".When that happens it will stay stuck loading the next file for a few minutes, then restart itself into the Windows Error Recovery screen.When I try start-up repair, it goes to a blank black screen and repeats the procedure above (ie. it gets stuck and restarts a few minutes later) When I hard-shut down by pressing the power button, a BSoD appears for a fraction of a second right before it dies.What could the problem be, and what can I do to fix it? I have the windows 7 install disk, if needed. Should I go ahead and try an installation repair using the disk?

Earlier today my second GTX 680 came in the mail. I opened up my PC to install it and after putting it in and attempting to boot my PC it gets stuck while loading windows. I tried safe mode and it got stuck on classpnp.sys. I've attempted removing my second 680, my SSD, put in a boot CD. Nothing seems to be working.

My parent's Desktop was having a side x side error and i've been trying to help her get it repaired. Her problem is that none of the programs will open except for internet explorer. All other applications give the sxstrace.exe error and won't open. I advised her to hit F8 and get into safe mode so I could try and help her further. She couldn't get that to work so I had her force safe mode through msconfig. That worked and got her into safe mode and she's still getting the sxs error and can't get anything to work for her. I advised her to go back into mconfig and uncheck the safe mode boot and wait til I come home and fix it. Now the problem is when she tries opening the msconfig, she gets an error on that saying it can't open the application with the error code 0xc000142 Now she's stuck in safe mode with no networking and the computer is basically useless. I'm 800 miles from home and won't be there until thanksgiving and i'm trying to help her over the phone so im kind of limited here. I was trying to get remote assist going for her but she couldn't install that either without the sxstrace.exe error.
they're running windows 7, If i remember correctly it's the x64 version.

Like the title says, my computer is stuck on a black screen.I downloaded an update and was instructed to restart the computer. After restarting the computer it went to a black screen. It won't do anything past that. I've tried starting it in safe mode but always with the same result. I have no idea what to do with this short of taking it to Best Buy to have the geek squad take a look at it and frankly I don't feel like doing that.

My HP Pavillion G6 laptop recently had a hard disk (I think) error and I was forced to use a clean install to keep on using my computer. After the clean install, everything seems to be working fine and for a week or so there have been no problems whatsoever. Just this afternoon,my computer failed to start, it was stuck at the "Starting Windows" screen. Safe mode refused to work either, stuck at the loading drivers screen. I have not changed my computer in any way before. I tried to use startup repair and it went on FOREVER. LKGC failed too. I am currently contemplating another minimized image recovery, but i fear that my HD has failed. I am most confused as to why there were no warning signs after my clean install, computer ran just like when i first bought it. T

After attempting to start my Laptop in Safe Mode, it loaded drivers normally only to crash a few seconds later. A prompt message appears but is impossible to read because Windows immediately reboots upon showing the prompt.

I was using EASUS partitioning tool to repartition my hard disc a few days ago as my C: drive was running out of space. I merged the C: drive (which is my system drive) with my D: drive (which contains a lot of data as well). All seems to be going well, but after the usual reconfiguration and restart, my windows 7 is stuck in the startup repair screen. Windows is trying to repair my startup without success, which is resulting in a loop. Fortunately i am able to go into safe mode and save my data.

A friend asked me to look at their Acer laptop since it was acting up. It was riddled with viruses so I did a system restore. It is now stuck on a loop saying that Windows could not finish installation. Please restart to finish. I've restarted it several times and am still getting this message. I've used the system restore on several other computers and laptops and have not had this problem.

Okay so i have this machine, acer m3100, that originally had windows vista. I tried to do a clean install of windows 7, with an original windows 7 installation cd.Everything would go okay until right after the computer restarts and goes to the part of COMPLETING INSTALLATION. At that moment my screen suddenly flashes with the blue screen of death. i wasnt able to right the error that shows up though. Then the computer restarts and goes to setup devices and right after that an error message appears saying, windows did not complete installation, due to an unexpected restart, restart the computer and restart the installation. If i click okay it will go into an endless loop. Restarting one time after another. So i thought i would install windows vista again. Try to make things the way they were before, but i get the same error. i'm only able to install xp. With XP everything works fine. I do want to be able to install windows 7 though.

I have a windows 7 pro 64 bit HP desktop computer that will not load windows. I have tried safemode, safemode w/ networking, and last know good config. I've run startup repair both from windowsRE and an original windows 7 pro disk. I have attempted multiple system restores (non destructive) to a number of different dates. The system restores say that they work but the machine still loops.
I know it's just some small windows corruption. I would have no trouble backing up my files with a linux distribution live flash drive and restoring the OS but I REALLY don't want to do that. How can I identify and repair the problem without starting from scratch. I'm familiar with msdos cli, but don't know which commands (if any) will help. I also don't know of any live CD's/ tools that will allow me to fix this problem. My problem here is simply lack of information.

When I tried to boot Windows 7 yesterday, I got a prompt saying that a disk check had been scheduled. I initially thought this got stuck because it seemed to freeze on 10% and the numbers alongside that figure didn't go up. I rebooted my computer and let it start again, after a few hours(!) the disk check finished and started on another of my drives. Again, I let this complete and it eventually rebooted itself. Upon rebooting it however, it did the exact same thing and appears to be in a loop just doing the disk check over and over.
I Googled this and opened the command prompt and checked all my drives (it disk checked f and c) but none are marked as dirty. I ran the command to stop the disk check on all drives anyway but still the problem persists.
Right at the start it says I can cancel the check by pressing any key on the keyboard but for some reason, it doesn't work - not sure if it's not recognising the keyboard or not.
I've also tried to boot into safe mode to see if that bypasses it but that hangs at classpnp.sys so that's a no go right now as well. I tried renaming the file to classpnp.old as a forum suggested but it blue screens and restarts if I do that. I'm currently trying a linux boot cd to replace to file to see if that works.

when I was playing a game and it crashed on a loading screen, I then could only boot into windows extremely slowly so I knew something was wrong. Since then I have booted into safe mode and done a virus check and it found nothing, I had then done a start up repair multiple times and for one reason or another the system would then reboot just as the login screen is loading. I have recently de fragmented the drive externally and run a slow disk check which found nothing. I've launched start up repair again which says it's unable to fix the problem and I can't boot into safe mode because it'll reboot. I should also mention I was having problems with the drive a few weeks ago where I was getting different error messages before booting but I managed to sort that out. If a solution can't be found it would be safe to say the drive is failing. Here is the bsod when I disabled automatic rebooting along with the startup repair error.

A Dell Inspiron E1705, w/ 2x2gb mem, 500 gb hd, ATI Radeon x1400 vid and Win 7.There were no Dell drivers or programs and the system BIOS was ver A01. Checking the Dell website against the Service Tag, I found 22 drivers and programs specific to the computer. Most of them ran and installed under Win 7 with no trouble. The last one was the bios flash utility program to update the bios to ver A10. The bios flashed, seemed to go ok. But on system reboot, after the initial screem about resetting the memory sticks, the computer is stuck in an infinite reboot loop.It loads the initial POST screen, completes the POST, seeks for its boot device and when it finds and starts to access the installed HD it reboots. I have reset all the bios settings to factory default settings. I have pulled the system battery and "cleared the cmos", but no joy there. I have created a bootable usb flash drive with another Dell laptop, and the computer will boot from that. I have other bootable cd's, and the computer will boot from them. I can use the bootable cd's to determine that the programs they run (freeware backup programs and a copy of bart pe) can access the installed hd,and see the files there, so the installed hd is intact. But i still can't get the computer to boot from it.My first thought was to reinstall the ver A01 bios, but it would not complete the process and remained at ver .A10. I was able to flash bios A09, and then A07, etc, all the way back to ver A04. But after that I could go back no further, A02 and A01 flash utilities returned an error message. If I found some compatible mem sticks and a smaller hd, installed them, could I reflash bios ver A02 or A01? Would that do me any good? (I have 2 x 256 mg mem sticks from a dell inspiron 5100 which I upgraded to 2x1gb, and a 40 gb 2.5in hd that also came out of the 5100, so I could use those parts in the e1705 to reflash the earlier bios)

i installed LibUSB-Win32- drivers so i could use iRecovery on my iPhone,on completion of installation of LibUSB my keyboard and mouse turned off, well all of my USB was disabled. so i was forced to restart, sadly same thing, login screen no keyboard or mouse, i tried in safemode, same thing. however my keyboard works in CMOS and BIOS so i know its a OS issue. and this only happened when i installled LIBUSB, i looked it up and tried manually removing LibUSB using the Win7 setup disks command prompt. i deleted LibUSB0.sys out of Windows/Systen32/Drivers so that LibUSB wont be called upon during start up, however doing this has now meant my PC will reboot after loading Windows even in safemode, the Starting Windows screen appears. fades and riight before it goes to the login screen it restarts, Safemode too. i have no Restore points and i cannot and i mean Cannot Format this harddisk, its not backed up and i have over 400GB of data i absolutely NEED.Im so stuck its not funny i have no idea what to do to get windows booting again and without this silly LibUSB stuff! i dont have aany PS./2 Ports on my mobo either!, what can i do >? Please ive asked everywhere and no one knows what i can do except reformat.

So I booted up my PC today and every single time it would get past the windows loading screen, a BSOD would flash on the screen for a split second and reboot. I tried booting into safe mode and that would not work either. The next step I figured would be to format and do a clean install, but here's the thing... Windows didn't even recognize my partition! It has my other 2 HDDs but not my Windows 7 partition. The HDD in question shows up in BIOS, but not in Windows. So, should I just get a new HDD? Startup Repair didn't work either, as it just hung/froze.
