Windows 10: My computer freezes and the screen flashes

It all started today when I was just on Firefox and it said GAH your tab just crashed. I was like ok I guess il just restart Firefox but then my entire screen froze and went black and flickered. As I'm writing this , I just got a green screen saying critical process died. I updated the system to see if it would fix it but after it was done it did this. laptop type is a Acer nitro 5 and I just use it for gamingSpecs:GTX 1650Core i5 10th gen16 GB of ram

Computer/ Screen freezing

As i mentioned before i flashed my RX480 Strix into RX580 Strix.
Since a couple days ago i have been having a screen freezing while i'm playing, mostly GTA V.
What really happens is: during a long gameplay about 1 hour or so my screen freezes, and after 30 seconds my computer just restarts by itself and i receive a BIOS message noticing me that there is no ''Bootable disk''.
If i restart my computer i keep getting this error as long as i still try to reset.
This thing gets solved if i turn off my pc in the power button and press it again to turn it on. By doing this, the computer just boots flawlessly and as it should normal behave.
My point is: is this a GPU problem caused by the flash i made around March 2017, is it a bad or not enough PSU ( it has 40A in the 12V rail ), is this it a bad HDD ( i already did hard stress HDD tests and they were fine ) or is my motherboard faulty?
Can you help?
And sorry for this long post.

 

Computer/ Screen freezing

Just flash it back to the original Bios.
And just overclock the card manually.
No real benefit from 580 bios imo.
