PC turns on fo a few secons then shuts off

[TLucks]

When I have the 4 pin power connector plugged in my pc turns on for a few seconds then turns off. When I have the cable unplugged it turns on and the fans spin but I see nothing on my monitor.

From reading this I'd assume you're having a major overheating problem, maybe try giving more details? Tell me more in depth of the problem because I wouldn't want to give a very vague answer.

I doubt it's overheating, at least not that quickly, but yes, we definitely need more info.

I'm upgrading form an old system. Everything is new except for the case hard drive and PSU. The MOBO is a H110m-a CPU is an i5-7500 the ram is crucial 2x4GB DDR4 2133 GPU is an EVGA 3GB 1060 the old PSU is a Thunder V2 535w. I've just put everything together and it seems to be turning on but after about 5 seconds it turns off again. If this helps when i have the 4 pin connector unplugged from the ATX 12v connector the PC stays on but I get no display on my monitor.

That's your problem, right there. Yes that board supports Kaby Lake CPU's, but NOT without a BIOS update, which it probably didn't ship with.

Thank for the reply! I'm new to building PC's and such. Can I update the BIOS manually or will I have to return the parts?

If you know someone with a Skylake chip, or could get one somehow, you could use that to update the BIOS, but other than that, yeah, you'd need to return the board and get a 200 series board (if you want to use that CPU).

Alright man, thank you so much for the help!
