One day I was playing csgo and my pc just crashed out of no where, basically blue screened. I turn it back on and I had windows 10 at the time nothing worked could click anything or start up cmd or command prompt nothing. so I opened up the recovery mode and thought it would be smart to reset my hard driver. After that I manually had to get my drivers and such back but I have integrated graphics called intel HD and so I thought everything was fine and I could play and get all my games back like normal but no the only games I could play without failure were league of legends, black desert online, terraria, warthunder. Alot of games that didnt work were csgo, garrys mod, h1z1, and many others. I dont know what the problem is I think its something to do with dll files and im stuck with windows 7 every time I go for windows 10 it fails.
