Hello gents recently for the past 5 months my pc has been underperforming extremely any game I would play for example, Red Dead 2, Hell Divers 2, Payday 3, Detroit Become Human, Elden ring, and so on. Any of these games I would play from the highest to the lowest graphics my pc would cap itself at 30-20-10-6fps then caps itself at that fps. I took my pc to CentreCom a couple days ago to get it stress tested only for them to come back 4 days later to say "your missing some files which we just installed for you". then yesterday after getting it back for 6 hours it worked as it shouldve but then went back to its original issue. I have also found out that my gpu utility is spiking uncontrollably from 100-50-79-0-5-68-55-100-99 etc. i dont know what to do at this point and really bummed with this system i have done my own stress testing and this is what i found if possible can i get some type of support by what any of this means?
