Windows 10: WHEA unoccrectable error

Recently I have WHEA Uncorrectable error BSOD once per few days on my laptop Dell Latitude e7250. I've tested memory with some programs: Memtest86, GoldMemory, HCI Memtest. These programs don't detect errors. I've also done torture tests with Prime95. Prime95 also doesn't show any errors however after dozens minutes of running this test, Windows shutdown itselfs because of too much CPU temperature Core Temps shows above 100 degrees during running this test.Here's theare are minidump files of some BSODs.https://drive.google.com/file/d/1qrpxunWnTtLDObgsE4SPou0vZMxUtSzS/view?usp=sharinghttps://

WHEA Error - Please Help

Everything on my computer has been running flawlessly since building it a few months ago. For the last week, I've been getting random WHEA errors. I assumed they would go away on their own since it was a generic error every time. Today, I got fed up and reinstalled windows. About 15 minutes into the new installation, I get another WHEA error. I googled it and decided to get blue screen viewer to determine the root of the problem. I have no clue how to read this error log though and need help in a big way. Can someone please direct me on how to fix this crap? Let me know what other information is needed. I'm going crazy over here.

whea warning? cache hierarchy error

I just noticed a whea warning in my event log stating a hardware error was corrected and it was reported by a cpu core. the error type was a cache hierarchy error. i know OCing can cause some of these whea errors, and it seems most people just ignore them, but im just wondering if this one is anything to worry about. my processor is overclocked, but i can pass numerous stress tests and games for hours, without any issues or errors in the even log. i think the pc my have even been idle at the time this was reported , or i was gaming . But again usually there are no errors regardless of what the pc is doing.
anyway, i was just wondering if anyone had some info on this error since googling it comes up with a bunch of different whea errors and no real explanation other than ocing can cause them.
