Fps suddenly dropped (virus?)?

Hey had about 4 hours ago about 200-300 fps in minecraft and now only 50-80 fps why is that? My pages suddenly load very slowly and my mouse and apps were dead. My buddy said my GPU was overheated, is that correct? Even only in minecraft is it used to 100%. However, I also have the thought that a virus could be responsible. Could it? If so, please tell me how to remove it. Thank you!

Please help! Did my pc only have a virus for 6 months? Which was a true one-time birthday present because of the 1k cost.

Maybe the info helps that I stumbled through my headset cable 2 weeks ago and then my pc fell over. However, these problems did not exist then.

any help would be great!

Jo no offense but what do you expect for the answer? You write 2 assumptions and say you have less FPS. Unfortunately, we can't help you with the information you want me to deal with it in more detail

Has the PC been shut down in the meantime? If not, you littered the RAM during that time. Turn off the PC, wait a little so that the temperature can normalize if it is too high, which would then not be unlikely, and then restart your PC.
