MacOS Big Sur crashing randomly

I recently install MacOS Big Sur on a Kepler GT 710, Ivy Bridge i5 3550, and H61 motherboard but it randomly crashes. At random times my monitors turn black, audio stops, and i have to turn off my computer from it's power button. Any help will be appreciated.

Specs:

GT 710 (kepler)

i5 3550

H61 motherboard
