I was recently gifted new pc parts (mobo, cpu, psu, gpu, ram) to build a completely new computer using only my old case. After installing everything correctly (as far as I'm aware) I tried booting it up. It runs perfectly for about 1-2 minutes, and then the display cuts out. I can be sitting in BIOS settings or starting Windows, and it will happen regardless. There is no onboard graphics slot to try. I have played musical chairs with my old parts and the new mobo, but no combo seems to fix the problem. I'm unable to run the mobo driver disc because the display shuts off too quickly.
