How long since a deep cleaning?
Tested with the cover off so you can see if any fans have slowed since new?
Since last week, my computer has started to lag when I started playing games, which was solved after a reboot. However, on Friday, rebooting did not help and no matter how many times, the problem was still there. The lag seems to affect my whole computer: My fps goes to single digit, the audio lags, and my ping goes to ~1500. The problem happened once a long time ago (~1 year?) when I accidentally plugged my speaker cord into the wrong hole, but the problem was solved once I removed it, at least until now. Additionally, this problem seems only happen when I'm gaming and it also only happens to specific games (CSGO, LOL, Fortnite). Here is a link to my specs https://imgur.com/a/lveCd
These are what I have tried so far:
-reinstalled my audio driver
-reinstalled my GPU
-scanned and removed some threat files w/ Malwarebytes
-ran CrystalDisk info, drives seem fine
-ran chkdsk C: /R
-ran Tweaker's Windows' Repair
-reinstalled Windows 7
