Question Random No Signal on Monitor while Gaming

[CashBank]

I just bought a pre-owned gaming PC. I benchmarked it before buying and everything seemed fine. After playing Fortnite on it for about 3 hours, the screen turns black and says "No Signal." My PC is still on and the monitor is still on. Now after starting Fortnite the same thing happens but only after about 2-3 minutes.

PC Specs:
-Intel Core i7-7700 (4.2 GHz Turbo, 8MB Cache)
-16GB 2400MHz DDR4 RAM
-Nvidia GTX 1080 8GB GDDR5X Graphics CArd
-2TB 7200 RPM Hard Drive + 240 GB SSD

Please let me know how to fix it.

Hi. I am not quite sure what the psu is, but the pc is an alienware aurora R6. Gpu doesn't get higher than 72 and the cpu doesn't get higher than 60 from what i saw yesterday.

The PSU is your power supply unit
You want to make sure it's got enough wattage to supply your equipment with.
