Question

PC powers up but does not boot ( black screen )

Sep 17, 2017 9:00PM PDT

Hey all, as you can read the title i'm having a comp issue here. It powers up, fans spinning but that's about it.. screen stays black nothing boots. ( Screen works 100 % tried it on my PS3 and also tried th pc on an other screen , it doesnt boot either). What I have done so far: I have tested the PSU with a paperclip, it works. I have taken out the ram, cleaned it with an erazer. I have taken out both of my ram sticks and my motherboard keeps beeping so I'm assuming my mobo is not dead. I have pulled out the CPU fan and powered up to see if my cpu heats up, it does, so I guess it works ? I have taken out my nvidia gtx card, still same result it doesnt start.. als unplugged my hard disk and dvd disks.. still nothing. I have removed my CMOS battery and put it back in with, however I havent tried out a new one yet. What should I do if a new CMOS battery does not work ? Did I miss something ? pleas help ..

If it doesn't even show the BIOS startup screen, and doesn't go into the BIOS setup if you press that key (F2 or Del or F10 or escape or whatever it is on your motherboard), it's either the PSU, the motherboard, the RAM or the CPU or the graphics (either the integrated or the separate card, whatever you connect the monitor to).

So you start replacing parts until it works in a cardboard test.

So I took both my ram sticks out and powered up the pc, it keeps beeping like " beep - pauze - beep - pauze " its unlimited, so I tried both ram sticks on the left ram slot, no beeps when I power up, however when I try them both on the right it beeps.. does that mean my right RAM slot is broken ? Also why is it not booting since ive only used one ram stick on the working slot .. is it my PSU? please help
