So I built a pc and it was working fine until yesterday night I was downloading csgo so I left it open and I watched netflix and when I came back the monitor mouse and keyboard are off so I tried powering it off and turning it on again and now when windows starts after a few seconds the monitor mouse and keyboard just turns off, I tried removing the videocard and I connected it with the built in and it's still the same, I tried changing the ram slot it's still the same, I tried changing the battery still the same, I also tried removing one hdd coz I have 2 connected and it's still the same. Pls help I really need to use my pc
