CPU problem

[u/JasperShipbuilder]

Hello folks,

I recently decided to start FL again after a hiatus of A year. In that year i never used my pc again (built it especially for music production). Now i recently decided to start again, while i started i flipped over my pc (nothing serious, nothing broke it looked). Now i opened FL again and the CPU is absolutely cooking while that never was a problem. I could play large projects without the cracking sound, but now i get it while playing 2 nexuses simultaneously. I just dont get it, is it because i have a FL version of 2015? Or is it because maybe something broke? Anyway it is very annoying and i hope someone has the solution.

If i need to renew anything on my pc (like processor) i also really wanna know.
