Pc starts for 5 seconds than turns off

[Khye]

Today I bought brand new parts for my pc
- msi gtx 1050 graphics card
- corsair cx750m 750w power supply
- wd blue 2tb hdd
- hyperx fury 240gb ssd
- cooler master n300 case
To go with my older parts
- Asrock z77 extreme6 motherboard
- Intel i5 3.2ghz processor
- 2x g.skill 4gb ram

I assembled the rig myself and now it just turns on for exactly 5 seconds and then turns off. At first I thought the front power button was wired wrong, as I can't turn it on from the front power button, only the switch at the back from the psu. I'm also thinking that my case is missing a cable as I've seen people talking about a 4-pin connector and I do not have any 4-pins in my case.

I've looked through countless forums and YouTube videos and have tried the following:
- removing and replacing ram
- removing and replacing cmos battery
- checking all cables are secure

It also would seems like there is an issue with my psu but it's brand new so I doubt it is faulty

Thanks for your help

Are the standoffs the brass screws? If so then no

These are standoffs:

You need to have them between the board and the case. And only in the spots where there are screw holes in the Motherboard.

I'll pull apart the rig now and add the standoffs. Will probably take 10 minutes

If there are no standoffs (thats if the case didnt have any in it), you'll have to remove the mobo and install them. The mobo goes on top then you screw it down

Otherwise it'll short

Putting in standoffs worked, thanks for the help everyone
