I don't know what happen to my desktop PC, but it doesn't turn on. My desktop is home-building which i built 4 years ago. It runs well until this morning. I try to turn it on but there is nothing of working sign. This happened yesterday as well. But after about 15', it turned on automatically. However, it couldn't repeat today. I am wondering what the problem is, because I checked everything I could think of. I unplugged every USB connections and reconnect them. I checked my power cable and replaced a new one. I checked my reset and power buttons behind and in front of it, they all are at right positions. So I think the problem is inside my desktop but I don't know what it is.
I need some advisories about this problem.

Thanks,

Since its not turning on I'd start by trying a power supply from another working computer.

Something must be creating a shortcut internally, like a defective memory stick, or loose video card.

So try to barebone the machine.

Thank you for replying me. If power supply is causing the problem, I think I can fix it by myself. However, I am wondering that there is other impossible ability caused by other internal components such as motherboard or else. I'm not so sure how I can detect this problem.

Yes, it could be anything, and we could keep guessing for days, but at some point you have to start swapping out parts with known working parts from other computers or new ones. Generally when a computer that has been working for a while and then suddenly quits powering on at all the PSU is the first suspect.
