Cmos reset issue

[PCLover45]

I Got and HP Omen 45L PC for christmas and recently, I been starting to get CMOS reset error and im not sure what it is caused by?

Its predictable? For some reason. Happen twice already and this is what it does.

I run a VR headset on my PC so I dont know if its related to the issue but here what happens.  I start getting random FPS drops for a good 20 second then it spikes back up, Then it start to be constant low fps, so I restart my pc, then it boot normally, however I cannot run any game and it crashes, then I restart it again, and it boots weird and it cycles untill it gives me the CMOS error. There two time it has happend and each being diffrent from one another.

Reset 1: I got an insecure boot error messages, then I had to reset my boot keys and my TPM. However I had to reinstall window due to me not having my bitlocker key in my Microsoft account. After this I replaced my CMOS battery with a brand new one.

Reset 2: CMOS reset again but when I burned the Windows Installer ISO of a flash drive, I disable bitlocker so I didnt encounter it this time. But I had to reset my PC because its ran into a incessable boot error in windows and it would not repair itself, even when using command prompt. Then I had to disable RAID and choose AHCI for SATA options, then I could repair my PC through a reset.

Ive ran dionosgtics in the BIOS and everything comes clean so Im stuck on what to do to solve this problem permanently because its really annoying. 

Thank you for you Time
