[SOLVED] pc freeze for seconds and fps drop

[dimifok]

Hello guys im new here. I have and issue with my pc. Last week my pc started lags and freezes sound and display on games for a sec. I tried to check my ram but it was ok . I also check hdd and ssd (ok too). Then i check gpu all fine. But keep freezes and fps drop. I was playing fine until this day. I made a format(not fully..from windows menu) Actually that helped me for one week and today started doing the same thing. What can i do ? is the psu problem ?

my specs:
win 10pro 64bit
cpu amd ryzen 5 3600
gpu radeon rx 580 sapphire 8vram
ram 8gb (1 stick)
hdd 1tb wd
ssd l7 evo 120gb
motherboard a320m pro max(msi)
psu 500w thermaltake smart rgb

ram 8gb (1 stick)

Getting another stick will help. Gaming and performance is better in Dual Channel mode.

What are your idle and underload temps?
