So I have been having an issue for awhile that has seemed to turn into quite a rabbit hole. For awhile now every time I close a game on Steam, Steam stops responding for about 10-15 seconds or so. Then I started having problems with games. Dota2 would take a long time to load in, Rocket leagues wouldn't recognize my controller for about 45 - 1 minute after loading into the game and other games would have varying issues that fall into the same line. Then I started looking into stuff like real-time audio latency, which I've noticed nvlddmkm.sys has a very high DPC count. I also have a fairly high hard pagefault count as well. I have been tearing my hair out trying to find the culprit of this for a week now.

If the computer is a desktop can you post the brand and model name or number of the power supply (PSU).

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.
