Hey everyone i own a dell inspiron 7567 laptop over the past couple of months i have been having trouble with my laptop's gaming performance 

 

So naturally after weeks of talking with dell they asked me to do a system reinstall and asked to check my performance and later since there was no improvement they replaced my motherboard and my graphics card along with the cooling fans 

 

Even after this i did not get any improvement in my PC's gaming performance so they suggested me to use -: 

"Intel Extreme Tuning Utility" and set the "Core voltage offset" to "-0.100" from "0" and asked me to record my issues 

 

The laptop was working fine when suddenly after like a day it suddenly turned off without any warning or error message not even 

BSOD 

 

I have attached a video stating what is happening exactly (attached a gdrive share link at the end of the document and in the      

beginning)

 

This happend first and i tried to run System repaid and System Restore but nothing fixed the problem 

 

However inspite of all this i was able to boot into Safe mode with networking (Thats how im making this post here) safe mode works fine without any crashes 

 

Then i followed a few steps like doing a SFC scan which said windows found some corrupt files and could not fix them then after following a few steps from  the internet and with no luck with them too i decided to do a complete OS reinstall 

 

I have 2 hard disk one normal 1TB hard disk and 1 256gb M.2 SATA SSD (Windows is in the SSD)

 

i created a bootable usb and booted in with it and formatted my C drive ie my SSD and performed a clean install of windows and ran SFC scan again this time too it raised a few errors but this time it said windows successfully repaired all the files and after a reboot i performed another scan it showed no errors and said that "no integrity violations were found"

 

Naturally after a fresh install i started updating my windows 10 and when it asked to reboot to finish update the same thing repeated and i was unable to use the PC other than in Safe mode 

Again i booted in with my USB and performed a clean install of the OS and this time the first time itself SFC scan did not give out any violations and i thought maybe i had to perform the above mentioned "Intel Extreme Tuning Utility" steps for the PC to function and i performed that 

 

After this the PC did start to work and i was able to boot in and install all necessary software but when i changed my power settings to high performance my laptop instantly crashed and it was the same situation over again 

 

Is this a problem with my motherboard or is it a problem with my Operating system or a problem in my BIOS due to the use of the "Intel Extreme Tuning Utility" i'm not sure 

 

Sorry for the long post please give you're suggestions as to what could be causing the problem and any potential ways to fix it 

 

Thank You

Did you undo the settings you did in BIOS?

i didnt make the changes in the BIOS itself since this CPU cannot be overclocked or underclocked manually they suggested me to use the Intel Extreme Tuning Utility and manually change the core offset voltage there thats all i did and it is after that this all happend

Quick question to all you guys like i said my motherboard got replaced and after that my microphone stopped working and there was nothing i could do to fix it can this be because of a faulty motherboard or a faulty PSU inside the laptop since i am using my lap in safe mode i cant tell

I didn't say anything about over- or underclocking. But like the Dell support said, you can do undervolting and other voltage tricks. And using XTU does those changed to BIOS from Windows.

 

But I'm bit confused now. If you wrote this chronologically, you did system refresh and then changed voltage (didn't undervolt it btw). After that you got all the issues, you can access Safe Mode, but not in normal mode. Hence question, is BIOS reseted or not?

Its not PSU, I can say that. More likely mobo. So back to Dell support you go.

to put it in order after the issue first started occuring i did a system reset and then started using it assuming everything was alright i started using my pc then the same issue occurred again after which i followed the exact steps suggested by DELL this time and reinstalled windows and all the drivers and then used the XTU tool too to set the core voltage offset to -0.100 and even after that the same thing happend
