I could use some help. I think I've narrowed down my computer's power cycling issue to either the motherboard front panel header or the front panel power/reset connectors. The power cycling doesn't happen on software reboot or reset switch. It only happens when using the power button. I'm going to try to eliminate it down to either the mobo or case connectors. Could I the connectors be bad, if so how is that? Could the pin headers be messed up or something? What I want to know is if I am on the right track, or is it something else(short, low wattage to parts, bad heat sink mount, etc.)?

Thanks in advance for the help.
 
From what i can make of what your saying it sounds like you got the power switch and reset connected incorrectly.

I just looked a few minutes ago, and as far as I can tell they are in the right spot. Short of the power cycling, they do work. For example, the power button (tries to) turn it on, and the reset button resets the computer.

Also, for further reference, this didn't happen with my last mobo in the same case.
 
Maybe check the power options to select what the power switch does when you press it.

might be a broken switch.
 
Swap the power and reset switches round and see if it cycles when you hit the reset switch (Which will now turn it on). Another thing I'd do is remove the front panel connectors completely and use a screw driver on the two power switch pins on he motherboard. This would rule out the possibility of other damage in the front panel. Just obviously be careful of sticking a screw driver inside your computer when its powered, and be very careful not to slip near the pins and short something. Other option to do the same would be get some of the power switch connectors with a bit of wire, connect them to the mobo then touch the two ends of the wire to power up.

u can buy a power button most places for a few bugs so why even try to use a screwdriver?

since flavinator don't write what case it is, he could be lucky there is a replacement pcb he can get from the manufactor or pay it cheap from them.

I don't like spending my bugs when I don't need to :)

Yeah, could of even broken one of the wires too.

Safer way would to use a jumper pin.
 
Thanks for the help. Might try to see if I can use a jumper thing from an old IDE hard drive. Would that work?
 
A jumper block is a jumper block...
 
My system did this where I would hit the power button and it would get halfway through post and shut off. Powering it on the second time worked fin a few weeks later my system would randomly shut off gaming or idle at the desktop reading something. Later it got even more pronounced and happened more frequently. It ended up being my PSU.

Just an idea.

As I originally thought it was my switch before the random power offs at the desktop. Remember though yours might not be degenerating at the rate mine did if it is the problem.

That's a specific thing with Seasonic PSU's, there's some strange switching mechanism that's a safety switch that powers down the PC when there's a problem. If OP has a Seasonic PSU, that is his issue. @the54thvoid can confirm this

EDIT: Correct me if I'm wrong, the RM series from Corsair is Seasonic made?
 
I just got one myself good to know in event i ever have a issue...
 
I've decided I'm going to try removing my CF to see if it's the PSU not being able to handle powering on. If so, I'm getting a higher wattage CPU.

I wouldnt know my seasonic doesnt do it my raidmax was the one that was bad. Infact I do know what you are talking about but I will say in that this particular issue was a power saving function availible on some motherboards that made seasonics make noise. Interestingly enough this was limited to seasonic PSUs as the OEM ones made for corsair etc had a different controller.

EDIT: Sorry @RCoon that was rude as f@#$ im not feeling well today.

yes, but dont leave it on there, otherwise it would be the same as holding the button down.

Do you think my issue could be that my PSU doesn't have enough wattage to start my all the parts in my rig at once
 
why on earth use a jumper?? that will harm it most likely. just use a flat head screw driver.

Because there is less chance of hitting more than just the 2 pins you want to connect.

any new(post 09) motherboards have atleast 1 pin spacing between different connections,
