So I was watching a video.. At the same time doing a scan.. When suddenly my screen went dark.. My computer was still on but monitor signal was lost.. I turn it off, turn it back on all fans turn on including amd apu stock cooler fan. But no video signal.. I have already taken everything apart and just left apu and PSU and motherboard fans spin but no video output on any port.. Specs are amd apu a6800k stock cooler, adata ram 8g running 2100 that's the stock ram speed.. Gigabyte motherboard edit 2 I have tried booting just one stick of ram nothing changes.. Also their is no light going to keyboard when the PC turns on.. Keyboard lights never come on also mouse lights..other than that HDD spin, apu fan spins..also I don't think my case speaker ever work because since it was build it never made a single sound ever.excuse bad grammer using a phone because PC is nuts help please
