WHEA UNCORRECTABLE ERROR, can someone advise something?

Question

Iron

Greetings! My laptop started BSOD with WHEA UNCORRECTABLE ERROR. Once a day, twice. In the device manager there was an "unknown PCI device", I sinned on it. I found several drivers by hardware id, the device appeared in the "device manager" and began to appear as it should. But the errors did not stop pouring in. They also became more frequent, yesterday and the day before yesterday, in general, every ~ 2 hours. Hard checked, checked the RAM, did stress tests, everything is fine. It just knocks out a BSOD at a certain moment, it can be loaded, or it can stand idle ... I experimented: I turned off the device completely, the errors disappeared, everything works stably, but if you do a "shutdown" through the start, it seems to start to turn off as usual, and then the screen turns off, but everything else works. The cooler is noisy The USB device is working, the backlight is on, etc. When you reboot through the start - the same thing, the screen turns off, everything else works and does not reboot .. in this case, output 1 is forcibly turned off with the button (press it). I already asked a question on this topic, but the answer did not help me (Why is the blue screen constantly popping up (WHEA UNCORRECTABLE ERROR)? ). Any help, please, I will be very grateful!

What helped me: Completely formatted the hard drive, installed another ten, someone's assembly, for some reason many firewood was not installed automatically. As a result, through the driver booster, I installed the firewood, including the device "... A324", some of it was installed from the laptop's website and everything was fine!

Answer 2

This is a PCH SPI Controller, which is something from the chipset and can unpredictably affect anything.
I would advise you to reinstall the intel chipset driver by downloading the appropriate version from the laptop site, or picking it up on the intel site
