As the title stated, the computer i'm building isn't posting. The fans and the l.e.d's will come on briefly (4-7 seconds) then turn off, everything is plugged in as it should be (i know this because it occasionally will stay on). Not sure if this is related or not but when it does stay on there is no video output, and the cpu i have has integrated graphics (plan to upgrade asap).
 
Recheck your connections, you may have a short or something not plugged in all the way.
 
I checked the connections, they're all the way in. Would a faulty PSU explain why I have no video output when it does actually run?
 
Does the motherboard have a diagnostic LED? If not you should be getting a beep code from the speaker, assuming you've connected it to the mobo, when it stays on. The error code can help you figure out what is halting the POST process.

The first thing I would try is unplugging the power from everything except the mobo, and any SATA plugs, then re-seat the RAM.

If that doesn't work, I would try booting with each stick of RAM on its own if you're running with more than one.
 
Stupid question, but is your motherboard secured in your case using the provided offsets and motherboard screws?
 
the motherboard oddly enough didnt come with screws or offsets, had to use the offsets that were already in the case and screws from an older junk computer.

So you're sure the motherboard is electrically isolated from the case?

Also, motherboards and power supplies can come with 20- or 24-pin ATX. On the same topic, EPS comes in 4- and 8-pin varieties. Make sure the proper cable from the power supply are plugged in. Be careful because 8-pin EPS looks very similar to 8-pin PCI-E.
 
Yeah the case will come with standoffs, not the motherboard.

The diagnostic code will help you figure out which part is bad. Does the motherboard have a diagnostic LED or did it come with a small black speaker?

Edit: Armenius makes a good point. Forgetting to plug in the CPU power connector can cause something like this to happen.
 
I assume the mobo is electronically isolated, i have it on offsets.

I have the 8 pin eps cord in, the pce e cord is a 6/8.
 
I originally did forget to plug in the cpu power connector and while it was similar, the power would just turn on and stay off. This time the fans flicker on and off in timed intervals.
 
Last thing I can think of if it's not a short:

Has the HSF assembly been properly attached to the motherboard and is it making good contact with the CPU? I had an issue previously where one of the pins holding the HSF to my CPU came lose, and the thermal protection would trip as the CPU overheated, causing the computer to shut off after a few seconds. Had to remove it, clean it, and reapply thermal paste before reattaching to the mobo.
 
its a new build and i just put on the heatsink today, i followed the directions to the dot so i doubt its the heatsink, but im not sure.

EDIT: not sure why, but its running right now, no problems except i still dont have video output
 
The mobo and ram are brand new, the cpu i bought used off ebay. i dont think its the mobo, when there is no ram in it beeps like it should.
 
What CPU heatsink are you using if the CPU is used?

When it does stay on do you hear a single beep or nothing?
 
im using a cooler master 212 evo, and no, no beeps

EDIT: found a 2 digit diagnostic post card with old supplies, the psu gives full power and when it does turn on fully the card says 60

Is it a 'b' or a '6'? The 6 will have a dash at the top, b will not (its a hexadecimal status code).
 
its a 6, the user manual says different things for different bios's and im not sure which bios i have

EDIT: i have click bios 2

You didn't put any extra motherboard risers on the case did you? I've had a few customers complaining about this after their builds and each and every one was extra motherboard risers shorting out the board. One guy had every single spot filled, amazing.
 
MSI uses the AMI BIOS and a list of status codes is here. Status 0x60 is "DXE Core is started," which means that the basic self tests have completed and system initialization is starting (see here).

More than likely there is a problem with the mobo, although it could also be that the mobo isn't compatible with the RAM you're using.
 
its a possiblity, im having a frined lend me his ram for a quick test to see if theres a problem with that ram, but as far as i know g.skills ripjaws 1X8 arecompatible, same voltage and everything
 
I've read about people having issues with G.Skill and the MSI Z87 board I'm running although mine works fine. But on first boot the mobo should bring the RAM up at 1333 MHz anyhow so more than likely its a motherboard issue.

I would also check to make sure none of the pins in the CPU socket were bent if/when you end up disassembling it.
 
im running a z77 which may have the same issue as the z87, and if i cant find a solution to the problem sometime tonight i'll be taking it apart tomorrow to have each part checked.
