Question How to diagnose problem?

[mcas19]

In the past month or so, my computer's been having problems playing certain games but not others. I can't determine why though. I'm an avid League of Legends player among many others and a good portion of my games have massive frame drops almost constantly and some run 100% fine. It doesn't seem to depend on graphical intensity or RAM requirements, so I am at a loss on how to solve this one.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. To add, have you fried uninstalling your GPU drivers with DDU and then manually reinstalling the latest drivers for your GPU?
