Question My PC's performance has recently worsened significantly

[Lightningdash12]

I've noticed that in both games and idle tasks, performance has been noticeably worse. My GPU becomes at unreasonable usage (90-100%) and very hot when playing low end games and giving lower than normal frame rate+stuttering. Additionally, my CPU has been running very loud while processing idle tasks and gets random spikes in usage with the fans starting to spin fast during browsing and simple tasks. I have never experienced this in my PC throughout my 2 years of use and would really like help to decide if I need to replace any parts or whether it's a software issue. I've tried a clean reboot of Windows 10, virus scans, checking task manager, updating graphics drivers from the official site multiple times but none of this has helped.

My specs are:
Corsair RGB spec delta case with original case fans
Ryzen 7 3700x with stock cooler
Radeon 5700XT
MSI B450 TOMAHAWK MAX
CORSAIR - Vengeance PRO 32GB 2x16GB 3200MHz
Seasonic - SSR-650GB3, 650W 80+ Bronze PSU
Crucial - P5 1TB Internal SSD PCIe Gen 3 x4 NVMe
1920x1080 monitor 144hz


Thanks all.

Have you checked temperatures?
HWInfo is excellent free software

GPU runs at 50c idle but quickly spikes up to 80-90c when playing a non-demanding game.
CPU is 60 on idle and 70-80 while gaming.
