Can't get my newly built PC to turn on

[calvincroy01]

Hello

Recently I've just made a new PC and decided to keep some parts from my old one.
It was a Compaq Presario CQ5210Y desktop PC. The only thing I kept was the case because my motherboard, a Gigabyte H110M-A would fit.
I got all the everything in place and go to turn it on and I can't get it on.
I think it's because the front panel cord doesn't really fit but I need a second opinion.

What CPU? If it's kaby lake you'll need a skylake CPU to update the bios in order to get your kaby lake cpu to work. (Or take your board to a computer shop and have them update your bios) or return your board for a b250 one

The CPU I have is an Intel i3
I'm not really sure how to check if it's kaby lake like you say but I can't even get the computer to start. Most of the parts are brand new

Which i3 if it starts with a 7 it won't work without a bios update which you can't do without a skylake cpu

do you have the old CPU? you will need the old CPU to flash the BIOS to accept the new CPU.
what parts do you have exactly, knowing this will help us help you.

If the cable from the on switch doesn't reach the motherboard you got a real problem. You might need to cut the cable and splice in more cable to make the plug reach the motherboard.

I know your trying to update your system on the cheap but you may be better off to buy yourself a new case & Power supply and get away from the proprietary issues.

Oh okay so that CPU is fine.

Take a screwdriver and touch both posts where the power s/w header should be and see if it starts. The power button on your oem case might not work with a regular board.

motherboard and CPU will work fine together no BIOS conflicts.
