Question im having hardware issues and idk how to pinpoint them

[Axticy]

So I'm having performance issues with my pc, frame drops, stutters, and more recently crashes( pc just freezes completely, I have to press reset button on case.) I used to have a 6600xt and i upgraded recently to 4070 super to fix the frame drop problem but it didn't fix it. I'm thinking of upgrading CPU to see maybe it’s a CPU issue. but idk what to do. Please just list things and I'll try them all.

PSU- 850W

PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?

Then it is software issue. Format your OS drive and make a new, clean Win installation.

So my power supply was bought new. I got it April 2023. Here’s the link. Segotep GM850 Power Supply 850W,... https://www.amazon.com/dp/B08F1NFSG4?ref=ppx_pop_mob_ap_share

And could you provide me a link on how to format the drive and do the widows install. Thank you for your comment. I have windows on my SSD, is that fine or should it be a thumb drive?
