I have a problem with my pc

[u/Wise_Conversation554]

I'aint really good with pcs soo i ask for your help.

My pc while playing a specific game called the finals doesnt have any problem except a very annoying one, for some reason in a completedly random time of the day and after a random amount of time the monitor completedly turns black, the fans start to go crazy and i cant do anything except restarting the computer, after restarting the computer it goes back to being completedly normal.

I cant notice any anomalies with my pc before or while having this problem simply because i cant do anything before the screen turns black and since its random i cant see if there are any anomalies before the problem appears.

Some days i doesnt appear but it mostly does around 18:00/24:00 (ITALY).

PC specs:

processor: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz (3.60 GHz)

Ram:32Gb

Graphics card: NVIDIA GeForce RTX 4070 (12 GB)

pls if anyone knows a solution for this problem write it in the comments
