I9-9900K issue

[Ghost113]

About month ago my Asus TUF Z370 Plus Gaming died.

Got Asus Prime Z390A and put all back together. 

Done clean install of Win 11 and issue started.

Win 11 crash at random.

Tried Intel cpu test and win 11 crashed again.

CPU boot normally and in BIOS is detected with normal speed and everything.

Removed it and put old i3-8350K and system is stabile.

every time when win 11 crash I get  WHEA_UNCORRECTABLE_ERROR

Is it cpu damaged or what?

BIOS is up to date.Latest BIOS.

Win 11 is up to date.Win 11 was on old config and there was no issues.

CPU is water cooled.temp not going over 68 Celsius on full load.

PSU is tested and all is in green.It is stable and give specified voltage.

Memory is also tested and it is ok.

I had to put my old i3-8350K now and all is stabile.

Not a single issue.

Only issue I had is with 9900K

On my old now dead MBO 9900K was working without any issues.

Warranty is long gone.

That is a biggest issue.

I am sad because I can use it.

Truth is that PC helps me with my PTSD issues a lot.

I am one of many in my country that was forgotten and I now fight to get my war vet status so that i can get things back in order.

Truth is that I live with 143 euros a month and it is hard to get used 9900K for a long time.

I can't work due my PTSD issues and meds I am using.

Games help me focus my mind away from my suicide side.It is hard living.Every day is a strugle with my demons.
