System wont start

[blnswamy]

Hello everyone,

I built this PC back in 2016, and it has been working fine since them.

A couple of days back, it wont get back from the sleep mode. The PC is not dead, there is no response when i press the power button. I have unplugged the power supply, and put it back, bought a new PSU and tried to connect everything to the new one, but nothing seems to bring it back.

I am contemplating getting a new motherboard, but i am not sure.

I do not know the bios / firmware version.

 

Any tips or pointers of how i should fix this.

This, kind of sounds like a CPU issue. My first instincts tell me Cables->PSU->CPU->Mobo
Since you already bought a new PSU, I would try a different CPU.

Got it , thanks.

Since CPU is the most expensive in the entire list, i will try to replace it at last.

I just got a new mobo, which i will try today.
