Steam Games Not Launching (I’ve Tried Everything!)

I have had my Dell XPS 8900 for several years, during which I was able to play all of my Steam games just fine. Recently, I have found that nearly all of my Steam games crash/fail to launch, and the “running” status on Steam simply reverts back to “Play.” I’ve tried verifying files integrity, reinstalling each game, reinstalling Steam, and I even reset my pc to factory default. After downloading Steam on the fresh start, it still would not launch the Steam games. Any suggestions?
