Question RDR2 ruined my PC?

I clicked the "launch game" button for RDR2 on the Rockstar loader. Immediately, my monitor turned off and my processor's fan started spinning wildly. I couldn't turn on the monitor again -- no HDMI signal -- and my fans were still spinning wildly so I turned off the PC by the power button.

Now when I turn on the PC I get the message, "PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE(S) FOR THIS GRAPHICS CARD". I've never seen that message before. I tried switching to integrated graphics but, still, nothing's showing up.

Anyone know what could've happened??
