I would appreciate if anyone can shed some light into this:
I built a new pc. keeping some compononents from my previous one
2x 4GB Corsair Vengeance 1866Mhz DDR3
Intel Core i5-3570K
NZXT Phantom 410 case
Existing parts used:
Corsair HX 1000watt PSU
Sapphire ATI HD6870
2 x Western Digital Raptor
2 x ocz agility 3
Plugged in everything. Motherboard's led is turned on and green but when I try to hit the power button the fans spin for just a second and then stop and nothing happens. If I push the power button again nothing happens with the led still turned on.
Steps taken so far:
Checked every connection, ensured everything is in correct place, order.
Removed GPU, HDD, 1 ram, one at a time and at various combinations - No luck
Removed mobo from the case and plugged it to PSU to see if something is shorting it, again with GPU, 1 ram - No luck
I don't understand what is wrong. The mobo is getting power as can be seen from the led, also for a split sec the system seems to power up but only if I remove the PSU cable and put it back in.
You need a power good signal on the motherboard power connetor which is pin number 8 (gray) voltage should be between2.4v and 6.0v it takes around 0.1 to 0.5 seconds after you turn on the power switch.
