[SOLVED] Games crashing with a newer and better PC

[Josh needs help]

Hey guys!
I just bought a Ryzen 7 3700X, 16GB RAM UDIMM, MSI B450M-A PRO MAX mainboard and a Radeon RX 590. I overclocked my CPU at 4200 MHz with a Peak Core(s) Voltage of 1.325V. My problem is that games like Assassin's Creed Odyssey or Jedi Fallen Order crash in a weird way once I get into gameplay. My monitor suddenly goes black and displays: "No signal detected" but I can still hear and see the fans spinning and the LEDs of my case are still on. Maybe someone knows which component is causing the crash or why it occurs. The weird thing is that everything worked fine on my old system (Nvidia Geforce GTX 1050ti, Fx-4300 Quad Core Processor, ASRock N68-GS4 FX, 8GB RAM). I am on Windows 10 just in case that matters.

Take off all overclocking, then see if the problem continues. Did you reinstall Windows after upgrading? If no then also do this.

I've already taken off all overclocking. That didn't even allow me to boot into the game menu. How important is a reinstallation of Windows after an upgrade?

It’s highly recommended to do a fresh install of Windows with a motherboard change. Not doing so can cause a range of issues.
