I have pc i bought from a gaming cafe that closed down about 3 years back. From the start it had issues but since then I have changed the motherboard and processor and gpu.

It was working until may 2018 when It stopped working.

The issue I'm having now.. Is when i on the pc in the splash screen where it shows the mobo logo there is a loading circle and once that finishes the screen goes black and sometimes shows no signal after the splash screen... But once in a while it will boot the windows and log in but suddenly screen goes black...

I have removed the ram and cleaned it...
Removed the gpu and cleaned it.

I have tried to the mobo vga port to see if its a gpu problem but it doesn't seem likely

Please help
