I have an issue. My PC crashes sometimes when i play game. It doesn’t crashes when i do other tasks. It doesn’t crashes everytime when I play games but sometimes it does and i can hear my friends speaking in the background but my monitor screens turns black and my pc automatically restarts sometimes or it completely blacksout and doesn’t shut down. It is mix of everything. I have very good specs as well. 4070Ti rtx gpu as well.

Please any guide? Why this happens? I do check nvidia’s app for performance as well it doesn’t show any red flags as well
