maybe heat issue
-try to replace the thermal paste on the cpu/processor
-reinstall graphics driver or update to the latest version
- try to clean the ram sticks

My First guess would be your cpu overheating, check your thermals, when a cpu is too hot, it automatically shuts down the pc to protect itself.
Another guess would be a faulty, poor and/or unreliable psu.
If not, it's probably your gpu.
