My PC show no signs of life this morning.
Yesterday I had used it normally, still gaming and chilling, everything worked fine. This morning, when i first turned it on, there a flash of RGB light in my case then everything went dead silent. No POST, nothing. USB port still have power and my phone can charge normally. I tried everything, use paperclip method and the PSU run fine, swap out PSU, switch between RAM slot, remove GPU, clear cmos but still no sign of my pc coming back to life.
I have no clue what went wrong. I tried everything.

My PC specs:
Ryzen 7 1700
Asrock B450 pro4 f
8x2 GB RAM
MSI RX 6600 Mech

include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
