Pc suddenly starts lagging

[Embuer]

My PC never lagged, but since a few months it sometimes starts lagging for no reason.I use Chrome and after a while my PC starts to lag (same goes for Battlefront and Minecraft). When i look in the taskmanager my pc is not under heavy load.It only stops when I close all programs and restart them. I tried uninstalling Chrome and Avast but it didnt change anything. I also tried Tron Script.

PC parts:

400 Watt be quiet! System Power 9 Non-Modular 80+ Bronze
8GB Sapphire Radeon RX 570 Pulse Aktiv PCIe 3.0 x16
Gigabyte GA-A320M-S2H Rev. 2.0 AMD B350 So.AM4 Dual Channel DDR4 mATX
AMD Ryzen 5 1600X 6x 3.60GHz So.AM4 WOF
480GB Patriot Burst 2.5" (6.4cm) SATA 6Gb/s 3D-NAND TLC

Maybe your psu is not powerful enough for that system?

I hope this helps

Well your GPU recommends a 450 watt PSU at a minimum. You have a 400 watt PSU, and a bronze rated one at that. Does it list any protections on the box, like OVP or SCP?

I put my parts into a calculator and it shouldn't consume more than 350w. And if it was a PSU problem my PC would suddenly restart and have different problems than I have. Do you have an idea what could cause the problem?

Try these 2 commands in CMD as admin:

1) DISM /Online /Cleanup-Image /RestoreHealth

2) Sfc /scannow

 

If this doesn't help, create a new user in windows and try running the games from the new user account.

I fixed the problem with a bios update
