My problem is when I start my computer it starts for a second but then it shuts down immediately then it starts again. This is not everything. Sometimes it starts but never boots (monitor lights up), sometimes it gets to the booting screen then nothing happens, and 2 times it loaded straight to windows. I have new motherboard, ram and cpu, so I don't think it's those parts.
SPECS:
Cpu: i3-9100f
Gpu: Sapphire Pulse rx580 8gb
Mb: Gigabyte b365m ds3h
Ram: G.skill Aegis 3200mhz 8gb
Psu: an old Chieftech 500w 80+
