Hi, so when very recently my computer doesnt power on and upon changing my power supply, it worked fine for only about a week and same issue occured. I went to remove my cpu from my motherboard to see if the motherboard gets powered, to my surprise the motherboard gets powered. I placed back the gpu,it gets powered. But when i put back my cpu, it doesnt even post. Even after i used a spare motherboard and cpu processor.
May i know whats the problem?
 
I'm not sure of your problem. A defective motherboard, CPU, RAM, or PSU could prevent the system from booting. In addition a defective drive could prevent the operating system from loading.

Also a corrupted driver or BIOS may prevent the system from passing POST.

I would suggest reassembling the PC, and then clearing the CMOS then rebooting.

Here are some general troubleshooting checklists.

Here are some instructions on breadboarding the motherboard to narrow down the problem.

step 17 is there a speaker connected to the front panel? if not get one connected.

canned diagnostic speaker rant
The diagnostic speaker is the motherboards main diag feedback device.
the motherboard may be telling you where the problem is.
my speakers have this plug

I use lamp wire but any stranded wire will do. literally any stranded wires. strip one end like so

attach the stripped end into the speaker spring clips on the speaker.
the other end of the wire should be trimmed like so the semi strip

by doing a semi strip the wire case is now the socket.
plug one wire to the first pin, and the second onto the fourth pin.
power on the system and listen for beeps
end canned rant

now there is a speaker boot the system and listen for beeps. if you are getting no beeps, try forcing one. power off the system and remove all the RAM. Boot the system, the speaker should beep like an astro-droid*. if you cannot force a beep code in this manner it has been my experience that the motherboard is toast
