Cannot boot Windows 7 RRS feed

  • Question

  • I've got a notebook with Windows 7 SP1.

    Unfortunately my notebook does not boot anymore. Last time i deleted some "Temporary files" with Disk cleanup in Windows 7. After that, i first got some strange Rundll errors but i 've ignored the errors. At that moment my notebook started telling me my battery was low. After completion, i chose "Hibernate mode" as i don't like to wait after turning on my notebook. And i left the room.

    A wild guess of the cause: I think its might be possible that the notebook turned off because of the low battery while storing session on harddisk. Or the Windows 7 disk cleanup might have deleted some important.

    Next morning i tried to boot my notebook. The display showed "Starting Windows" which is strange for hibernation. It began drawing the Windows logo, but halfway the display freezed, then a blue screen showed up for about 0.5 sec and the notebook started to reboot.


    STOP: 0X0000007B (0XFFFFF880009A97E8, 0XFFFFFFFFC0000034,0x0000000000000000000000, 0x000000000000000000000000000000000)

    I've tried the following possible solutions:

    1. Running Kapsersky Rescue disc to scan the boot partitions and all the related files. No harmful files were found.

    2. Running Windows startup recovery multiple times. As result it tells me the computer cannot be repaired automatically.


    Problem signature:

    3. I tried running sfc /scanall in command prompt in Start up repair and Windows 7 install DVD. After completion it tells me some files were repaired. But no difference with boot.

    4. Disconnecting all wires and the SD-card, except for power. Disconnecting the battery.5. Boot in safe mode, but the screen freezed while loading, last line showed CLASSPNP.SYS. After, the blue screen again for 0.5 sec and reboot.

    5. Boot with last known good configuration, but reboot after half finishing to Windows logo drawing.

    6. Restoring BIOS settings to default. Changing SATA mode to SHI instead of AHCI.

    7. Windows sytem recovery from Windows 7 DVD, but it can not find previous back ups

    8. Loading Ubuntu OS from DVD for trying to access the hard drive. Hard drive is accessable, files were unharmed.

    9. I tried to replace Classpnp.sys with a backup from the harddisk and a copy downloaded from the internet. It did not work.

    10. I tried to "upgrade" Windows with help of my Windows installation DVD. It tells me to boot Windows and to try it again trough This Computer with Windows already runnig. And it can not run Windows...

    11. Memory test in startup repair mode. No errors.

    What else can i do? Reinstalling my system is NOT an option!

    Thanks for answering and have a nice day.
