Windows 10: Random Blue Screen on Startup

I've had this problem with two Windows 10 computers. One of them was an Acer laptop that we upgraded to Windows 10 and the other was a generic built PC. Both of them are working fine now but what causes this to happen? The repair tool didn't work and we had to format and reinstall.

Startup Blue Screen

Hi Jon,

Startup blue screen error(s) can occur if a problem causes your PC to shut down or restart unexpectedly. It could be due to the following:

• Outdated device software drivers
• Corrupted Windows update system files
• Software/Security conflicts

We would like to know some information:

• Did you get any blue screen stop error codes?
• Have you tried booting in Safe mode?

We suggest that you check this
article about troubleshooting blue screen errors and follow the troubleshooting steps provided there.

We will wait for your response

 

Blue screen and stop code

Hi
Jeferis,

There are a lot of factors for this matter to occur. To isolate the issue, we have some questions for you:

• 
  What activity have you done to
  trigger the NTFS and FAT FILE SYS loop?
  
• 
  were there any error messages?
  
• 
  What troubleshooting steps have you done so far?
  

It is possible that the
Boot
Sequence were corrupted by the previous activity which
triggered the Blue Screen Error and the loop. We recommend that you perform these
suggested troubleshooting
and see if there are any changes:

Startup Repair.


To access the
Startup Repair Screen, turn off the
PC 3-4 times(force shutdown),
while on the Blue screen Error. This will route you to the
Startup repair screen:

Advanced Boot Options > click Troubleshoot > Advanced options > Command Prompt

and run the following command:

Run SFC Scan:  

SFC
will
scan
and
run
an
automatic repair
to any
corrupted system files
that it will detect. We suggest that you perform it twice. To run an
SFC scan, follow these steps:  

• 
  Run
  Command Prompt as Administrator.  
  
• 
  Type
  sfc /scannow
  and hit
  Enter.   
  

Boot Record:

This will fix the corruptions on
boot records or boot
sequence. To run this command, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type the following command:  
  
  • 
    Bootrec /fixMBR  
    
  • 
    Bootrec /fixBoot
    
  • 
    Bootrec /rebuildBCD
    

Update us on how it goes.

Regards.

 

Trying to diagnose random blue screens

This is a Windows 10 Professional desktop, built seven years ago. It is starting to fail, with almost daily blue screens, and I'm trying to guess what part is failing. The candiates are naturally the motherboard, a RAM stick, or a video card.

The errors are almost always different, and there is almost never a culprit announced. Here are some examples:

• MEMORY_MMANAGEMENT
  
• IRQL_NOT_LESS_OR_EQUAL
  
• SYSTEM_SERVICE_EXCEPTION
  
• KMODE_EXCEPTION_NOT_HANDLED (mcdbus.sys)
  
• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
  

Eventually I will have to start removing all parts one by one, but I was wondering if these errors might suggest which part to check first.
