I have a ok pc, not the best though. It has a GTX 1060 6gb gpu and a i5 8400 cpu. Lately it has had problems with severel games such as Battelfront 2, Warzone and even pretty old games lik CSGO. Most of these games ran smoothely a month a go, but now they lag. I dont think it has anything to do with my internet connection because i have tried it at a friends house (with fibernet) and it lagged there too. Please help. Thank you in advance.

Check for any apps running in the background - maybe you got infected by some kind of "miner"?
You may also want to run things like adwcleaner: - it won't take long and if there's some infection going on, it may be able to find it.
Run DriveInfo app: and make sure you select one drive at a time and check the S.M.A.R.T. tab for each of them. See if any of the values are in red.
Running memtest86 for a whole night is a decent idea too.

Culprit could be also Windows doing something in the background. Do you have 100% HDD utilization all the time?
