GA-H67MA-UD3H-B3 Phase_LED Guide

[lorewap3]

I request that anyone know of a link that has what these Phase light combinations mean please post that link. It's not in the manual.

I'm troubleshooting this comp that won't boot. The monitors get no signal, whether using onboard, or either of my 2 video cards. The CPU fan does NOT turn on, but does of course when it boots properly so I'm ruling overheating out. This problem has been intermittent, only happening after being idle for 3+ hours and shutting itself off. Upon reboot the external fans come on so the PSU is supplying power but no signal gets to monitor.



16 G 1600mhz RAM
i5-2500 Intel CPU
Big Zalman CPU cooler fan
4 SATA Hard Drives, only one used at a time (I'm a backup freak. I hate downtime..   )
Radeon 6870 normally,
have Radeon 6950 as backup

Have switched out RAM, video cards, everything but CPU. But as monitors aren't even showing BIOS and CPU/CPU fan has worked and not changed since I built it last April, I really don't think the CPU went out. I want to know what the PHASE_LED light combos are as the bottom one is green and top stays red whenever it doesn't boot. Which as of now is always. It's either dead or dying I want to know for sure before I replace or RMA.


Thanks for any and all help,
Will

Hi and welcome.

It sounds to me like it has to do with the power saving settings. Try disabling all power saving devices and sleep settings in the BIOS and see if it still happens. Also disable the same settings in Windows.

Sounds like CPU may be faulty to me, the phase LED's are not an indication of anything when the system is not functioning properly.   I mean they are not troubleshooting LED's, they are only to indicate how many phases are loading at a time, so you can't use these to try and figure anything out.

Can you test that CPU on another board?  Or test another CPU on this board, to see if maybe the board is at fault?
