I am getting quite a lot of bugs since 9th November. I am a heavy productivity user. I use CPU for video editing, sound mixing, while I use my GPU for cuda programming.

For work I rely heavily on pdf editor, I am research scientist. And pdf Change is what we use. It started crashing. I checked event viewer and it says 0xc0000005 error.

I updated bios, drivers etc and ran all hardware scans viz. Memtest, SMART, OCCT, cinebench, and a few more no errors or crashes.

Then I noticed that windows files were corrupted to the point I couldn't run media creation tool.

I reinstalled windows and everything is the same. No improvement.

I saw a lot of reddit threads about memory leaks and faulty CPU that doesn't show any errors in tests. Is this one such case?

Anyone else have any idea to pin point what could be the culprit?

Sounds like memory corruption, unfortunately it's one of the hardest things to diagnose. Traditional memory tests with 64GB of DDR5 are unlikely to find anything, from what you described your system is so unstable that you should be able to find a simple reproducible scenario that just fails. For example, I've had more success with using COD Warzone as a memory test than any other tool out there.

Here's what I'd do. Make sure your BIOS is up to date (also, what's the mobo? is it QVL RAM?). Run your RAM at 4800, with Gear 4 (or whatever the 1:4 mode is called) and increase your VccSA just in case. If you have PCIe Gen 5, use gen 3/4 instead. Disable fTPM. Start with a fresh Windows install. Disable Windows VBS and subfeatures such as memory integrity. If that doesn't help, I'd try a different motherboard if I can. If not, different RAM. Only then would I blame the CPU itself.
