Asus H87-plus mobo power on problem

[guyman4000]

I wanted to upgrade my CPU and needed a new mobo to do so, so I got the an Asus H87 plus mobo and the i5 4570 to replace an Asus m4a7blt micro atx and an AMD phenom II x4 630 (or something like that).

Anyway, the swap was pretty painless, but on the first power on attempt the computer would not power on. I figured it was the power button and tried every single connector for my cases power button wire and nothing worked.

I then shorted the pins with a screwdriver to see if that worked, and it did, however the case turns off in under a second after all the lights and fans come on, even if I hold it against the pins.

I've read it could be a PSU problem, but everything worked absolutely fine with my old components, however it is a few years old (corsair TX650w, what it says on the side of it.) The light on the bottom of the board and also on my video card are lit when the PSU is plugged in.

Dead mobo? I hope it's just a dead mobo. I really don't want to replace more parts.

Well if you hold the screw driver to the pins then it will shut down, same as forcing shut down holding the power button in. I doubt it is the PSU so we are back to the board. Have you gone through this guide http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

Are both Power connectors to the mobo snug? (24 and the 4/8 pin by the CPU), have power to the GPU if using one? DRAM firmly inserted?

Check check check. After reading that checklist it sounds like a short, but I'm not too keen on this stuff. I just used the leftover board raiser things that the old board had in place and everything screwed in fine, but maybe its shorting out that way? Not sure.

Make sure you do not have an extra one in a bad spot.

Might want to pull the guts and bench it....if all fine on the bench, then check that you have a standoff for each hole in the mobo and ensure you screw into each one, have a guide that might help here:

Alright lined them all up properly and we have lift off, however...

PROBLEM #2 The cpu fan isn't spinning, and I'm getting three beeps as soon as I power on. The fan is plugged into the mobo. Any guesses?

 

[rolli59]

CPU fan connector? BOTH 24 pin and 4+4 pin plugged in?

 

[guyman4000]

Check, check, check.

 

[rolli59]

You have an extra CPU fan connector? Many boards have two.

 

[guyman4000]

No, just the one.

 

[guyman4000]

Could the cha_fan port work?

OH GOD I FORGOT TO UNRAVEL THE WIRE AROUND IT. Thanks a lot everyone, appreciate all the help.
