please i was wondering if there was someone out there who could help me!i have a pc i amtrying to fix and it has been giving me a lot of stress lately.The problem is, i put on the pc and it works perfectly fine.After working on it for at least 9 to 10 hours and switching it off and trying to put it on again,it boots but it does not show anything on the screen.i have changed the ram,the motherboard and also the cpu.but the problem still continues.please what can i do to rectify this problem?
