BSOD on Starting Windows...

[IoNGeNeRaL]

Hi guys.

So for some reason my system is blue screening just as it tries to load Windows. It lets me boot to safe mode but not normal. This started happening after I had been booted to Linux (USB) and finishing, I tried booting back to Windows and it just starts crashing. Not sure what's going on. Please help ASAP.

Additionally, I tried to do a startup repair and it returns saying the following:

Root cause found:
-----------------------------------
System volume on disk is corrupt.

Repair action: File system repair (chkdsk)
Result: Completed successfully. Error code = 0x0
Time taken: 36395 ms

-----------------------------------
-----------------------------------

It suggests I do what??

Hi IoNGeNeRaL,

The best suggestion is to remove Kaspersky for now

Kaspersky caused the crashes because of a pagefault due to an attempt to invalid memory what isn't allowed at this IRQL level or higher. IRQL is the priority scheme that the CPU uses when processing everything, this way the CPU knows what is for the hardware, what is for certain Windows mechanisms and what is for everything else.

How can I remove Kaspersky? I can't boot to normal mode and I can't remove in safe mode because it doesn't let me.

Please try the Kaspersky uninstall tool in safe mode :ar: https://support.kaspersky.com/common/service.aspx?el=1464#block1

 

[IoNGeNeRaL]

I'm currently doing that now. However, I don't see why Kaspersky is the cause of the crashes or why it's doing this.

 

[axe0]

As I tried to describe in my previous post Kaspersky is attempting to access invalid memory address at a priority level that only allows nonpaged memory to be accessed, the attempt of Kaspersky accessing the memory causes a pagefault and a pagefault is something that cannot occur, and would cause more problems if the BSOD wouldn't come in, at that priority level (or higher), that is why the crashes occur.

It's working now. Thank you once again, axe! I've given you a positive reputation for your time. Thanks man!
