PC powers up however no signal on the monitor and keyboard and mouse
Basically today i was using my pc as I normally do watching youtube and playing games, then my screen freezes with a weird buzzing noise, so i turn it off but when i turn it back on the system powers up however i now no longer get a signal, i bought this pc off amazon its called ADMI Gaming PC and i got early in the year and its been fine i have added a wifi card and upgraded the ram and its been working fine until today, what do i do?
