  1. Open Windows File Explore
  2. Navigate to C:\Windows\Minidump
  3. Copy the mini-dump files out onto your Desktop
  4. Do not use Winzip, use the built in facility in Windows
  5. Select those files on your Desktop, right click them and choose 'Send to' - Compressed (zipped) folder
  6. Upload the zip file to the Cloud (OneDrive, DropBox . . . etc.)
  7. Then post a link here to the zip file, so we can take a look for you . . .
might show more.

what are specs of the PC?

What BSOD code are you getting?

change the memory dump to kernel then at the next crash load the crash dump
c:\windows\memory.dmp into the debugger
then type the command
!pnptriage
it should give a good idea as to the problem.
or post the memory dump and someone with a debugger can take a look.

you can also try to update your chipset drivers from your motherboard vendor or cpu vendors website. (as a first fix attempt)
