Hello community…

Usually very good with troubleshooting and fixing…but not sure where to go with this one.

Switched on the main rig. Normal as expected POST. Main Windows 10 login screen.
I login…all of a sudden…garbled lines and dots on the screen…system throws up a BSOD….Win32kbase.sys. Auto restarts…

On reboot I notice that it is now POSTing….but I am getting garbled lines on the screen…so that is happening at POST. I can get into bios no issues…no garbled lines on the screen when in bios. Out of bios…system continues to load…but garbled lines on the screen.

System goes into auto-repair mode….still lines on the screen.

System cant do the repair and presents Advanced Options.

The rig now cycles between BOSD PAGE_FAULT_IN_NONPAGED_AREA Win32kbase.sys…auto-restarting and trying to do a system repair and failing.

Im really not sure where to start with this one. I am syspecting the mother board or graphics card since I am getting garbage on the screen during post…but not sure.

Here are some screen images

Any ideas? Help would be appreciated.

  Does your computer have onboard graphics? if it does try that to see if its a hardware problem
  Try a linux live cd/usb to see if it still has the same problem if it doesn't then its probably a software issue and not hardware

    Thanks for the suggestion.

    System doesnt have on-board graphics….but has a graphics card.

    I do have a spare graphics card and I will try that a bit later.

    Im really leaning toward a HW fault…mainly because at post and during OS load the screen is garbled.

    I have added a some images to the main post so you can see what is happening on the screen.

  Can you boot into the command prompt and run something like chkdsk /f <drive letter>?

    After it attempts a repair and fails it allows me to select advanced options, and from there there I can get to a command prompt.

    I can run CHKDSK /F…but this wouldnt explain or solve the garbage I am getting on screen before the OS even loads.

  Could also be RAM (or less likely the CPU) but yeah, definitely sounds like a hardware fault. Similar images online (with BSODs) were seemingly indicating GPU RAM failures.

  Without spare hardware to swap out for troubleshooting you're stuck though. Might actually need to take to a repair shop if you don't have any in-person contacts with spare hardware to test.

    Luckily I do have a spare GPU that I will try and see how I go.

    I would not likely go to a repair shop. I wouldnt be able to live down the shame :)…which is why I go to forums for some hints.

    thanks

  Thank you all that answered my post.

  I am back up.

  Issue was the GPU. Replaced with another and Im all good. Dont know why the other one died.
