Question PC Crashing, Please Help

Aug 26, 2020
My friend has this pc, and it keeps crashing when playing games (Counter Strike GO, Rainbow Six, GTAV, Watch Dogs 2) for around 20 minutes. It wouldn't shout down, the screen and the CPU unit is still on, but the screen would be just blank. Also the audio became like static stutter or something like that, then, we cant do anything but force restart the PC. Any idea what may have caused this ? I have underclock the GPU and its still the same, temps are OK (~75'C Max), Ram is OK ( i check on windows memory diagnostics), storage is also OK, we also have recently replaced the thermal paste on both the CPU and GPU.

Here are the specs :
  • Intel i5-2500
  • Biostar RX470
  • Kingston HyperX 1x8GB DDR3
  • HGST 512GB
  • Monitor : Lenovo D186wa
which power supply is it? brand and model

clean boot

check the memory by running usb autoinstaller (bootable USB flash drive)

How hot is the CPU getting?

update the BIOS of the motherboard

check the GPU in a different PC
