Random BSODs while idling/light workloads

Ignore the first BSOD on august 26th that was most probably caused by SVP as it was triggered by the graphics driver i've disabled svp since then and had no graphics driver related BSODs

the 3 after that happened in the short period after i installed new ram sticks(had 2 sticks of corsair ram got 2 crucial ram with the same specs they were either faulty or not compatible Ii guess ) the first two were while I was sleeping the last one was while I was browsing
I removed the new ram dimms and had no bsods for a while so I assumed it was them and returned them and got 2 new sticks of ram with the same exact part number as the ones I already had

kept the pc on for a week and no BSODs with the new new ram installed

today I was watching a video with mpc-hc and I got the 15th Sep. BSOD (which btw showed "kernel security check failure" on the actual screen but blue screen viewer shows no stop code when reading the minidump file for some reason)

which made me worried since that's a lot of bsods in a short period of time and I don't really have a lot of experience with debugging BSODs so O thought I'd ask here to be sure

ps:i also upgraded my gpu in the middle of all of this but the BSODs started before I did that . I know I should minimize changes while trying to figure out what is causing a bsod but i really wanted to play mankind divided and wasn't going to wait with a gpu in its box looking at me specially since I'm almost broke now

I just started getting these the other day after a 'Restart and Install Updates'. I figured it was a bad update. Tons of misleading diagnostics (Memtest86 stalled when running all cores Parallel, but passed when run sequentially). Reseated RAM, CPU, tried a different power supply, checked capacitors, etc.. It turned out to be a failing HD. Once I disconnected it, no more BSOD/Kernel Security issues. I've been building/repairing computers for over 20 years... this was a weird one. I'm not saying it's whats happening to you, but don't rule anything out

So I've had zero BSODs since then

but my pc did stop booting and it turned out that one of my newer RAM dimms was faulty and it gave up.

returned this second set of ram and ordered a newer 16gb kit that I'm using alone now

I'm gonna mark this as solved now
