FPS suddenly dropped during gameplay and can't fix it.

[PrimalVoid]

About 2-3 weeks ago I started having lagging issues with games that mostly rely on GPU. I recently had to replace my drives due to them failing, was hoping they'd have been the cause but that doesn't seem to be the case. Nothing's crashing as of yet really, just went from good FPS (60+ in most cases) in everything I play to 5-10fps. It first happened randomly while playing a modded MC pack. I've tested it on various games; MC, OldSchool Runescape is fine if shader packs are off (like 117 HD). Enshourded, New World, Eternal Strands, The Isle, and Satisfactory slow to a crawl. Games like Balatro, Bejeweled 3, Lucky Hunter all run fine. I've attached a CSV while running a stress test (following a guide here https://rtech.support/guides/hwinfo/). In Furmark under the parameters listed in that guide it was getting 2-6 fps max. The m.2 is completely new so it has a completely fresh install of windows. All drivers and windows are up-to-date as well as bios being the latest available. Everything but the PSU is no more than a year old. Also, as of now there haven't been any crashes that I've notice or remember atm.

My specs are:

• Windows 11 Home 64 bit
• MEG X570 UNIFY (MS-7C35) (BIOS Ver. E7C35AMD.AL1, latest)
• AMD Ryzen 7 3700X 8-Core
• 2x16GB G.SKILL Ripjaws V Series (Intel XMP) DDR4 3200MT/s
• XFX Speedster SWFT210 Radeon RX 7600XT
• Crucial T500 2TB Gen4 NVMe M.2
• 750W PSU (non-descript, got it from ibuypower a few years ago)
