Question UNSUPPORTED PROCESSOR

[cyanflare]

Hello, the issue im having is when booting into windows it goes into automatic repair and the BSODs with Unsupported processor. This is the first time it has happened. Is there any fix for this?

 

[Colif]

what are details of PC?

I assume it was working fine the day before you got error?

 

[cyanflare]

Yes it was working before.

Motherboard - MSI Gaming 6
CPU - i7 4790k
GPU - MSI GTX 980 Ti
Ram - HyperX Fury Black 16gb

Is CPU overclocked?
have you had any windows updates recently?

how up to date is the bios? https://www.msi.com/Motherboard/support/Z97A-GAMING-6#down-bios

 

[cyanflare]

The CPU is not overclocked.

I have no idea of there were any recent updates. how can i check?

The bios version is E7917IMS V10.0 with a build date of 01/20/2015

 

[Colif]

well, you can't check updates if you can't get into windows

that is the original bios that came with motherboard, its unlikely to me that it would suddenly cause this problem when CPU happily ran on it until now. Newest bios is A.3 dated 17th Feb 2016

this shows how to update bios

CPU is working or you wouldn't have gotten as far as you did. PC wouldn't have started at all. We need to test it somehow
Try this method to make a bootable version of Prime 95 and run it on CPU to test it is okay. - https://www.infopackets.com/news/10113/how-fix-bootable-prime95-stress-test-hardware

I've updated the bios and ran the stress test for about 15 mins and CPU is working.

Still getting error from windows?

 

[cyanflare]

Yes, im still getting the error.

I think i might have some corrupt files on my windows installation. I got another hard drive with a windows install from another computer, plugged it in and it booted up with no issues. Is there anyway to fix corrupted files?

 

[Colif]

Not easily. It isn't an error I have had to solve before, It is rather strange.

I would boot from the other hdd and copy anything off your normal C drive you want to keep, or did you remove that to test?
If you can, run this on CPU with other drive in it - https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool

Do you have a win 10 installer on USB? download the Windows 10 media creation tool and use it to make a win 10 installer on USB (if need be, do it on another PC) - it is a handy repair disk

If PC won't boot with that drive in it, we can still copy info off hdd by booting off the USB instead
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose command prompt
type notepad and press enter
in notepad, select file>open
Use file explorer to copy any files you need to save to USB or hdd

Is the best option to just backup files i need and reinstall windows?

 

[Colif]

Its just strange error to get, as I said, never seen it before and its not like I don't help people with windows errors.

I would test CPU using that tool and if 2 tests show it to be okay, then yes, backup and reinstall.
