Sudden poor performance

[Awakecloud]

I don't know if anyone can help me figure out what's happening. Last Monday i noticed that my pc performance was not what it used to be best way i could describe it would be like trying to play a game on a gaming laptop that's not plugged to its charger so sluggish and not getting the right frames and just generally wonky. PC boots and runs and i can still do stuff. I had bought a new PSU thinking it was maybe power related and that didn't fix my problem. I changed GPU's on my rig and that didn't change anything also tried my current one on a friends pc just to double check and its working fine. Friend of mine suggested that it could be the Mobo but I'm not sure if it is. Any ideas? 

 

Mobo: Asrock  B550M/ac

RAM: 16 GB 3600 MHz

CPU: Ryzen 7 3700x 

GPU: Zotac 3070

PSU: 650 wats but did buy a 750 (will probably return it)

Do you have any GPU overclocking tools running? Maybe software from Zotac? I had something like this happen to me when I accidentally set the Palit Thundermaster software to have an FPS target of "1" making any game unplayable while watching 60fps videos on youtube was fine. I did everything from DDU and reinstalling old and new drivers when the only thing I had to do was turn the slider up to max.

No i dont have any overclocking tools installed or running. and youtube kinda sorta runs fine for me every like 20-30 seconds you can hear the audio/vid freeze for like a second and resume as normal.
