Have I fried my RPI 4b?

Help! When I power up my RPI 4b the red power light comes on and the green next to it (which usually flashed on and off whilst booting) now just lights, blinks once and stays on. And nothing else happens . .
Should i start digging a small grave??

I would try to reload a new copy of of the os on the sd card, and see what happens.

Yes, thank you tthat did the trick, but i had to do a full on format of the SD card. Quick format was not good enough. Now all I need to find out is how i managed to corrupt the OS with adding a DAC to the Pi in Volumio.
