    Windows reboots undefinitely and Safemode doesn't work


    Hello,

    Today I have worked on my PC, everything was fine, and when I finished I shut it down. After 2 hours I opened it back, and when it got to the windows 7 logo screen, it showed a little part of it after which it restarted. This happened several times.

    After a crash, before the logo screen I would get to choose the option to launch startup repair, along with start windows normally. When I chose the first one, I would get to a window called System Recovery Options. Here, both my keyboard and my mouse stopped to function (keyboard got innactive but mouse was still flashing; keyboard is on USB, mouse on PS/2, and keyboard worked just fine before this menu), so, the only solution was to reboot.

    After that, I looked in the BIOS options, but with no success, as I already had enabled legacy USB support and keyboard USB support. Tried to load a failsafe configuration, then an optimized one, with no success.

    After that, before the logo screen, I pressed F8 and got to a menu with the options: repair your computer (which was equivalent to launch startup repair, so it failed with no mouse and keyboard working), safe mode, safe mode with networking/command prompt (all 3 failed, they stopped at system32/drivers/classpnp.sys; did a little research regarding this one, so first I renamed it, but those safemodes stopped just at the driver before this one, meaning probably the driver that loads after classpnp.sys may have a problem; after that, i renamed the drivers folder and took another drivers folder from another 32 bit windows 7 system, with no success - all those operations done in Ubuntu, as I use it on dual systems Grub Boot and Ubuntu works just fine, enable boot logging (which would create ntbtlog.txt, but it failed to create, probably because of the reason explained here: Ntbtlog.txt File Not Written When Boot Logging Is Enabled ); last good known configuration (which did nothing important); disable automatic restart on system failure (which would give me a blue screen with "a problem has been detected and windows has been shut down to prevent damage to your computer....***STOP: 0x0000007B (0xC877EB58, 0xC0000034, 0x00000000, 0x00000000)") and disable driver signature enforcement (which again did nothing).

    So, I decided to use a live CD, but because I didn't have the DVD at me, I decided to use an USB stick with the operating system on it. I inserted it, boot from it, and again, on the language select screen, mouse and keyboard stopped functioning. After that, I did a recovery USB, following Windows 7 - Create a system repair USB key from another system with windows 7 32 bit, and again, same failure because of mouse and keyboard.

    After that, I entered Ubuntu, opened the Gpart program, scanned my both NTFS windows partitions and the System Reserved one, they had no problems, after I used ntfsfix on them (they were located on /dev/sda1, /dev/sda2, /dev/sda3), and still there was no problem.

    I mention I did a memory check using memcheck from GRUB, and it was no problem, and 2 weeks ago I did a full windows hard disk scan for errors, few bad blocks were spotted and "fixed" (probably by fix it means they are checked so nothing will be written there in the future).


    I am very sorry for this wall of text (where I described everything I have tried to make it work, with no success), and hopefully I will be getting helpful replies to put my system back to work.

    Thank you a lot for your time and answers!

    Emily you most likely need to System Restore to before a bad driver was installed, since failure at boot animation is most often driver-related as this is when drivers load. So you need to get your keyboard working to access System Recovery Options
    to System Restore. Can you try a PS2 keyboard, or borrow another?

    Is there any chance your HD was changed from first boot in BIOS setup when you reset to defaults? Check to be sure.

    At the moment I don't have any PS2 keyboard, and all the computer shops only have USB ones...I will try to find a PS2 one, somehow.

    And regarding changes, nope, the same settings were on. Also, I did not install any new driver in the last 3-4 months (I used driverpack solution to install them). Last thing I remember is that when I shut it down, not sure last time before it stopped working or a day before, was that Windows installed one update before shutting down.

    If by chance I can't find a PS2 keyboard, are there other solutions for my problem, with using a USB one? Also, it's worth to say that I unplugged my USB keyboard before the system would boot Windows 7 installer from the USB stick, let only my PS2 mouse, and still I had no access to the interface (with my mouse). On a working laptop, this USB stick worked fine, I mean the keyboard and USB mouse were usable on language selection screen and after it.

    Ok, I managed to get a PS2 keyboard, and I could enter the windows 7 boot usb. From there, first I chose a startup repair, which failed after a time; after that, I chose system restore. Newest restore I could do instantly returned with an error. Tried older restores, including the oldest one, everything appeared fine, it showed finalising system restore, and after that a window with "system restore has failed", but with no error code or something like that. After I tried the last system restore, my computer restarted by itself.

    What should I do?

    EDIT1: at the moment I am using a command prompt from the system recovery options, and did a chkdsk /f /r /b D: (strangely, he considers D: to be the C: ).

    EDIT2: after using check disk, I tried again to enter in Windows, and this time it was success. I shut it down and restarted it, and again it was fine. Really strange. Probably those failed system restore did something after all.
    Any idea how can I see what caused the problem? I know it's something related to Event Viewer. I went to Windows Logs in this program, on Application and System folders, but strangely, nothing was reported in the last 24 hours (since my problem appeared).

    Sometimes when you get the error that System Restore did not complete in WinRE, it actually did complete and will boot to the desktop as a result. Is this what happened?

    You can gradually go over your Win7 most thoroughly to turn up any other issues and learn a lot more about it following the Troubleshooting Steps for Windows 7 which also offers useful optimizations and the tools and methods which work best for Win7.

    When I ran system restore in the recovery mode, it took around 3-4 mins to have it finished, and after "finishing the system restore" window appeared, next one said that the system restore has failed. It did not boot to the desktop, I had to restart the PC. When I restarted it and entered in windows, everything was fine, but I got a message about the failure of system restore, which I dismissed, and following next restart, it didn't appear anymore.
    Regarding the event viewer, I went to Custom -> Admin View, and there were tons of errors, but none during the time Windows I had this problem (one strange error said about a bad block in DVDRW drive, but I had nothing inside...).

    I hope it is not from my hardware, but, nevertheless, I will check the guide you gave me and try to follow as many steps as possible.

    Thank you for your time and helpful responses :)

    You can start with Step 5 if indications are that the hardware is sound, do the earlier steps later.
