I was leaving to work so I turned off my Pc. Once i got back from work, it wouldn't start. I unplugged and plugged everything back and it worked. Hours later, the lights blink and the energy goes off for a few seconds. Computer wouldn't start again. Then I removed everything and it started again. Before leaving to work today, I restart the computer, which worked normally. Then I turned off and tried to turn it on , which didnt work. Note: it wont turn anything one. Not a single light. Its like the PSU is dead. Then after removing all plugs , and plugging again, it works perfect.

I dont know why this is happening. Could be the PSU which I will try to test but I dont have the tools on me right now. Besides that, what else it could be?

sorry for broken english

If you say you removed everything and put it back it worked.
Wouldn't it be wise to remove one item at a time and find out which one is causing the problem (if its not PSU).

button is fine, I can even hold it for couple seconds to turn off the computer, and it will turn the computer on someday. But I will try touching the pins with something to see if it turns on.

So button isn't the problem. Tested the PSU alone and it lookslike thats the problem. Then fan is moving really slow and no energy is going through. I will buy a replacement today and see if it will work

I had this problem a few months back and it ended up being the motherboard. I tried a new PSU and it worked for about 30 secnods and shutdown again? I had a spare mobo and I installed it and it worked? If you have a spare one I could suggest swapping it and seening if it turns on?

No spares. But the PSU isnt working anyway, so i will just buy another one. The Pc was working fine, I turned it off, it never turned on again. So MOBO should still be working, but it is failing, and i will switch it soon. I will be home in 6 hours and will change the PSU. I will get back here to say what happened
