In the last 3 weeks I have had more replacement parts than ever before, but I must be missing something obvious. I've built quite a few systems before and had no issues with any of them. Hopefully you good folks can help with this one though...
I originally built a ITX system:
Intel Sandybridge i5-2500K
Corsair LP Vengeance (2 x 4GB) 1600MHz
AsRock Z68M-ITX/HT Mobo
Seasonic S12II-520 520W ATX12V PSU
I had intended this to be mounted in a Lian Li PC-Q11B case...
Working on a breadboard, I connected the up the CPU (with heatsink & fan), RAM and PSU to the Asrock. Briefly shorting the power headers started all fans running and lit a blue LED on the board (no beeps, as this board doesn't have a speaker header, as far as I can see). One second later, all fans powered down with the LED. It tried again, but powered down again and there it looped, unable to keep going for more than 1 second.
I swapped the Seasonic for the PSU on my current PC, which works. I can't recall the model at the moment though, but it is rated at 800W. Same problem. Just to be sure, the Seasonic ran my current PC without problem.
Next I pulled out the RAM, leaving just the CPU (with heatsink & fan) & PSU connected. This time the system didn't power down after 1 second, but I didn't get any beep codes or video output either. With one stick of RAM, back to on/off loop.
I swapped the RAM for some Kingston HyperX (2 x 4GB) 1600MHz, but nothing changed, still on/off loop.
Next I swapped the Mobo for a Zotac H61ITX-A-E. Still the same on/off loop with no beeps (the Zotec does have a speaker header on the mobo).
I have a replacement CPU on the way, but I assumed CPUs are really unlikely to be faulty.
All parts were brand new (except my existing PSU) from Amazon and I reseated everything a few times, just to be sure it was properly mounted.
Anybody have any ideas?
