Problem with New build (1st time builder)

afire90 · May 21, 2014

Hey guys, so i have just finished putting together my first build. When i went to power it, the fans, cpu liquid cooler, and sata devices all powered up however i got no display signal to my monitor. The case and cpu fans spun very fast for a couple of seconds and then started spinning much slower.

I do no have a motherboard speaker so i could not hear the beeps if there were any.

I have already checked all the solutions in the sticky troubleshooting thread and none worked. Could my mobo/cpu/ram be dead or is it something else? Thanks in advance=)

CPU: AMD A10-7850K 3.7GHz Quad-Core Processor ($169.99 @ Newegg)
CPU Cooler: Corsair H100i 77.0 CFM Liquid CPU Cooler ($89.99 @ Best Buy)
Motherboard: MSI A78M-E45 Micro ATX FM2+ Motherboard ($64.99 @ Micro Center)

Power Supply: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply ($59.99 @ Newegg)

The fans sinning fast and slow is normal: gets dust off.
Does the PC stay on or does it shut itself down?

it stays on, the only way to power it off is bye turning off the power supply, holding down the power button doesn't work

Have you got a diff monitor you could try?

You know the 24-pin motherboard connector? Make sure that's properly inserted. I was having the same problem as you, and it turned out that connector was a little loose.

SethJPC :

No, but i'm sure this monitor work fine, i tried it on other devices and it displays them without a problem

Graphiicz :

the motherboard connector appears to not be in all of the way, but i have applied as much force as i could dare and it wont go completely in. Should i apply more force?

afire90 :

What do mean by not all the way in? If the clip is in place it is fine, I doubt the PC would boot at all without it being in.

It is in place, seems to be a slight gap between the connector and the board. Could i just have a faulty motherboard?

SethJPC :

When this happened to me, it would turn on fine, except no signal on the monitor. However, at random times, the signal would work. Ever since I sorted out the connector it's been perfectly fine.

OP did you take it out then put it back in? Make sure all the pins line up properly.

No matter how much force I put it refused to go in more, however i do have it routed in a way where the 24pin cable is bent at a 90 degree angle. Could that be causing the problem? Also, if the mb connector wasn't in properly, wouldn't that not allow the cpu and its fan to turn on?

Ive read around and it says that sometimes the mobos need to be flashed with the latest bios to work with fm2+ processors. Could that be the problem here?
