First post on here, humbly requesting some help please.
New build components:
Gigabyte Z87X-UD4H Mobo.
i5 4570K CPU (stock cooler for now).
G.skill Rip-jaw 2133 2x4Gb RAM.
Gigabyte Radeon R90 280x GPU
Be Quite Power zone 750w PSU.
I 'Breadboard' assembled the above and powered up.
The system came on and the fans (GPU & CPU cooler) spun for about a second and cut out.
It then began a cycle- reboot cut out, reboot cut out and so on. I tuned off the PSU after 4 cycles.
My first reaction was to take out the GPU, that had no change. I don't know why, but I put the graphics card back and tried again. This time the Graphics card fans did not spin. The cooler fans did, but the same cycle of cutting out remained.
I removed the GPU and the RAM and tried again but with the same result.
I tried with a different PSU but the problem remains. I have even mounted the board in the case, taken of the cooler, cleaned and re-sat the Heat-sink with new thermal paste but still the power on fails and goes into this cycle.
I only have the Stock fan plugged in to the CPU fan socket and the Main ATX 24pin power connector
Am I missing something? Should there be another test I should do?
I don't know if this is the Mobo or the CPU or both.
This is my first build for 6 or 7 years so I'm at a newbie level again.
Can anyone help please?
Thanks
