Computer not booting! Please help

[Devun41]

When I start up the PC, the lights and fans turn on however the keyboard, mouse, and monitors do not work/display anything. Every blue moon it starts up fine given a good time for it to work (still rarely). I have tried restarting CMOS by removing the battery for 15 minutes, using one RAM stick at a time, using integrated graphics only, holding the power button with the psu unplugged, and just about everything except bench test b/c idk how to. This has started in the last 2 weeks and before that everything was working just fine and I havent switched anything out or what not. Im starting to think that it is either the hdd or the psu but I still have no clue it could be something totally different. When I used 1 RAM stick at a time, it has worked only twice and has not worked since (I have tried every slot with all 4 sticks I have). Any input is appreciated! This things a pain in my side I just wanna game.

I think you should try to use a different power supply. Sometimes power supplies burn out and stop producing power. It could also be that the power supply was being hurt by the mobo and your mobo could also be dying.

My first thought would go to the psu. Make sure both cables are well connected to your motherboard.
