Gigabyte GA-P55-UD4P Problem

"New build won't boot" checklist

http://www.tomshardware.com/forum/261145-31-build-post-...

Are you getting 'phase LEDs' on the MOBO when you try to power up? Do you have a case speaker installed? (I've run into lots of people who expect the 'bootup beeps' to come through their Log1 5.1 speakers on the audio plugs - don' work that way!) Does the CPU fan spin at all?

No LED's are lighting up. The manual says that they have to be turned on in the BIOS. I do have a case speaker hooked up. I pulled it out of another case. The CPU fan spins briefly then stops, the rest of the case fans stay on.


OK, I will try this next.

Maybe I will pull the HSF off too and see if there is anything interesting going under there.

I also think it is strange that it ran for two days without issue.

OK, so I pulled the MB out and hooked it up with a different power supply and it worked.

Then I pulled the case over and hooked it up that way and it worked.

Then I put the board back in the case and it worked.

Then I hooked the components up one at a time and it worked every time.

Right now it is setup and working but I am still concerned because I haven't really changed anything and it is working.

Is there anything I should be checking?

I have a GA-EP45, and i had a similar problem...my conclusion: something was making a short-circuit, because, with all components outside the case it worked. I believe that the boards with 2 oz cooper are more likelly to have this kind of problem, because the extra cooper conducts more eletricity...

What i have done to solve the problem: i have used a non-conductive material to isolate the case from the motherboard( i put only on the mounting holes)...

Sorry my bad english...

         

I am very late with a response, however, this may help someone else.

bilbat may have been a little abrasive laugh gifs, however, he is correct in that is not extra copper. The problem is a ground however, and ricbst was wise in trying to eliminate that threat.

Some motherboards induced a ground at various locations, one of which was along the back of the case. Although recently manufactured motherboards should not have a closed circuit problem, recently there was a danger.

Years ago ground protectors [for screws] used to be supplied with the motherboard, however, that is no longer done. I go to the extreme of making extra non-conductive standoffs to support motherboards.
