Hi all,
I've just acquired entirely new components for a new system from Newegg. The parts area as follows:
i7 3770k
ASUS p8z77-v/Thunderbolt Mobo
G.Skill Ripjaws 1600 RAM 16GB
Corsair 1050HX PSU
Noctua NH-D14 cooler
When I turn on the system, the red CPU led lights and the system immediately shuts off after spinning up some fans (CPU and CPU_Opt) for about 1 second. This is almost exactly the same as what was happening before Newegg RMAd the motherboard for me, except then it was powering up for about 5 seconds and then shutting down and back on for 5 seconds in an endless loop. It will not POST. The factory motherboard BIOS is 1708, which is quite recent.
-I have tried breadboxing the system.
-I have tried single sticks of RAM in every slot on the mobo to no avail.
-I have tried my other computer's PSU: Corsair 850HX that has worked beautifully for 3 years. Same result.
I have noticed that this motherboard will not power 3-pin fans on chassis fan headers 2 and 3...just like the RMAd one I sent back! All fans work when plugged into a functional power source. Both the 24-pin and 8-pin connectors are plugged into the board. The green power led is lit all the time.
The ASUS phone support tech told me it sounded like I had a defective mobo since it wouldn't post and it wouldn't spin up 3-pin fans on chassis fan headers 2 and 3. Do I have 2 dead mobos in a row?
Or could it be that the CPU led is right and the processer is actually DOA? I cannot see any bent pins on the CPU or mobo...and this is the second mobo with the same behavior.
Is there a short I am missing...even with the mobo sitting on a cardboard box?
Please help...I am so frustrated. Built 4 systems and NEVER had anything like this happen.
