New Build Help Before Smashing Everything to Pieces

avlnlady · Aug 7, 2015

Hello,

I am currently building a new system with the following specs:

intel i7-4790k (with included cpu fan)
Asus Z87-A motherboard
Corsair RM 750 PSU
EVGA GeForce GTX 970 4GB
16 GB RAM (Crucial Ballistix Sport 2x8GB)
fans, optical drives, ssd and hhds

I'm reusing an old case that I had - a Ultra Aluminus ATX

...and of course I cannot get things to fire up. The most I get out of it is the motherboard power light lights up and the CPU fan jostles when the power button is pressed but does not run.

Here is what I have tried to troubleshoot everything:
• removed a ram chip and tried, removed the other ram chip and tried
• powered another computer's motherboard with the PSU (plugged in the 24-pin and the 8-pin into other motherboard) - that computer's CPU fan powered up
• bought a new motherboard - Gigabyte GA-Z97X-UD5H
• took the case power/reset/LED wires from another case (same computer that we powered with the PSU so I know the wires are working) and plugged them in (into the newly installed Gigabyte motherboard) and pressed that power button - CPU fan still just jostles
• removed the CPU to make sure none of the pins were bent (none were bent on either motherboard)
• reset the CMOS on the Asus motherboard before buying new motherboard

If anyone can help with some additional troubleshooting ideas or potential problems, I would appreciate it. I really hope that it isn't a DOA CPU or CPU fan...but that's the only thing I can think that hasn't been tested.

Thanks!!!

Well if you have trouble shot everything but the case and the CPU, then logic dictates that is one of them, can you power the computer on from the motherboard, if you can then it is the case and if that still fails then I would think it is the CPU.

Probably the CPU, the most likely time for a CPU to die is in the factory, it's rare that one dies from use unless you physically hit it or break it. Try a completely different set of RAM, if it's not that, it's probably the CPU.

Thanks for the feedback. Decided to pull out the motherboard and try to run it with one stick of RAM and the 24-pin and 12v connected. Turns out I wasn't getting the 24-pin pushed in all the way and finally (without having the motherboard mounted) it snapped it correctly.

I think I was just being too cautious pushing the connector in too hard as the board gives a little on its mounting screws.

Feeling dumb but glad it's working

Your Z87 actually wouldn't have worked anyways. There is a 99% chance it would have needed a BIOS update first.
