Random BSOD

[Morg101]

so i recently built a new PC from scratch and had a guy install a thermaltake cpu cooler and after that ive had random BSOD's and complete PC crashes, game crashes. at random, sometimes it goes days without issue then BOOM. its been like this for 2 months or so, and at one point the PC stopped posting but after a CMOS battery reset it posted again then back to random blue screens and crashes. and i get error codes like irql not less or equal i get kmode exception not handled, those are the 2 recent ones i got and ive done 3d marks and cinebench and memtest all successfully for hours at a time, my temps are always low. i have no idea what the issue is . and ive had like 3 other ppl try to help me but im not the best with this stuff...its so sad though i just want this to work i spent a lot of money on all this stuff
my specs are Ryzen 5 3600x CPU 16gb Corsair 2666mhz ram (2 8gb sticks) GTX 1660 SUPER GPU 750w thermaltake power supply 80+ bronze certified motherboard is a MSI b450 gaming plus max i have a 512gb m.2 NVME i have a 2TB firecuda SSHD i have a 250gb EVO SSD and a 500GB HDD

nothing happens for no reason.

these seem like driver issues. try reinstalling them

i know this will take a while but can we get a list of your most frequent error codes?

[Morg101]

IRQL_NOT_LESS_OR_EQUAL
KMODE_EXCEPTION_NOT_HANDLED

SYSTEM_SERVICE_EXCEPTION

SYSTEM_STOP_EXCEPTION
ive reinstalled and updated my drivers many times they are all up to date it says.
i even have a Pro edition of Driver Booster 7 which scans my pc and updates stuff for me
Ive ruled out it being the PSU, the case, the keyboard the mouse, headset, mic, monitors, i even ruled out my house cuz i got a UPS. i did memtest86 multiple times it says my ram is fine. i am at a loss this has been going on for so long now like 2 months, and at one point the thing wouldnt even post until i did a cmos battery reset and re seated the gpu and ram
