Computer starts to lag after ~10min of gaming

Apr 3, 2018 8:41PM PDT

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
-used AdwCleaner
-ran CrystalDisk info, drives seem fine
-ran chkdsk C: /R
-ran Tweaker's Windows' Repair
-reinstalled Windows 7

That GPU looks warm.

How long since a deep cleaning?
Tested with the cover off so you can see if any fans have slowed since new?

Overheating

I agree, that GPU is really warm, Try using compressed air, do not use a vacuum, to get dust out of the case, and make sure that there is enough airflow getting into the case.

SeaTools diagnostics

You can try grabbing our free diagnostic software SeaTools and running the long generic (takes awhile but scans all sectors of the drive) to see if it's the hard drive.
