Cpu LED On ASUS Maximus IV GENE-Z/GEN3 Motherboard (Mysterious Problem)

post #1 of 5
Thread Starter 
Hello,

My build as the one in my signature.

I built the system in December 2012.

Everything was spotless until early May 2012. What happens is

1) When I turn on the computer, it would turn on, however no POST and it would stay that way. I would then have to turn off the power from the power socket, and when I power on from the socket, the system boots without any problems. When there is no POST, the CPU LED on the mothboard stays on.

2) I continued to live with it for a few weeks until the system starts to "turn off". No BSOD, it just turn's off, and restarts however the CPU LED stays on , and I have to do what i did in "1" and it boots.

I believed my motherboard was faulty. Sent it for RMA. Got it back about 45 days later (Yes, ASUS is slow here). Fixed everything and it is the same as "1". Decided that perhaps it is the CPU which is faulty. Sent it for RMA about a month ago, and the retailer called. They said that their supplier is out of i5 2500Ks and would upgrade my unit to an i5 3570K processor for an additional fee of (Conversion from RM to USD = $25). Received the processor today and fixed everything once again. However, the problem as stated in "1" still exist.

Could it be that the RAM that is faulty? I doubled checked every component and my psu is connected to every point on the motherboard. Tried running it without any USB devices attached , and it made no difference.

Test your RAM, one stick at a time, using Memtest86+.

But I think your problem is the PSU. I would have swapped for another PSU and tested my system and you'll see an RMA for the PSU in your future.

Appreciate the reply.

But is it really possible that the PSU might cause the cpu led error?

Most likely it is the ECC server ram, yank them out and run the rig without them. Use the A2 and B2 slots ( red ones ) and save up for some good Ram like G Skills 2 x 4 gig at 2400 mhz ( Trident X ) made for Ivy. BTW did you get an error code on your mobo ? cheers.gif

Tried running memtest for about 9 hours +

5 Pass with 0 errors.

I was using the ECC RAM since December 2011 and there was no such coinsurance until May 2012.

I will remove the ECC RAM and see if it makes any difference.

There is no error code on the mobo when the cpu LED lights up.

edit:

Removed the ECC RAM and inserted the desktop RAM into the first slot.

Turned it on, and the same thing occurs. CPU LED turns on. Switched the computer off from the main switch and in a split second turned it on, and the computer booted.

Now I can conclude that the RAM is not causing this.

Could such occurrence really be cause by a PSU?
