I turned on my computer today and it took around 3 minutes to boot up instead of the usual 20 seconds. When I logged in, everything was super laggy and applications took ages to open. Looking at monitoring software like MSI Afterburner, I noticed that both my CPU and GPU are staying at low temperatures (37°C and 27°C, respectively) even when I'm trying to launch games. Their usage increases, but the temps remain idle, and the games are unplayable; even watching YouTube is a struggle with constant stuttering.
I've restarted my PC several times, but that hasn't helped. It was working perfectly fine just yesterday. I can't find any driver updates, but historically, not having up-to-date drivers hasn't caused issues like this before. I have a 13900K CPU and a 4090 GPU. The only problem I've encountered previously was crashing, which I resolved by turning off Nvidia Shadowplay.

Make sure your power settings are not on 'Power Saver.' Sometimes switches to that mode can throttle performance. Set it to 'High Performance' to see if that helps.
If the BIOS is up to date, try checking your background processes. Sometimes, a rogue application can hog resources, causing everything else to lag. Open Task Manager and see if anything unusual is running.
Have you checked if there’s a BIOS update available? Since you’re running a 13th Gen CPU, updating the BIOS could resolve any potential degrading issues that might affect performance.
