Hi,

Firstly, I have read the FAQ.

My problem:
I installed new pair of Kingston 8GB DDR3 1600 kit (2 pcs.) ( Datasheet for it )
on my Asus P6T Deluxe mobo with i7 920 processor.

Before upgrading I have not had any problems at all and now my computer will not power up at all. The fans don't spin up, only the mobo power switch and reset buttons are blinking with fast pace like flickering.

Nothing else was touched during the install. I have tried reseting the CMOS by taking out the battery for few minutes.

Oh and I have also tried to change the old RAM back and the problem stays.

Thanks.

Just checked this and none of the fans start to spin. Including power supply fan. Yet there's a flickering light on the power and reset buttons.

If none of the fans worked, turn them off immediately. You don't want your computer be toast because of stupid overheating.

Have you checked all the cable from power supply to your motherboard? There are 2 main cable to take note, the 24pin (large one) and 4pin (yellow and black cable) and make sure both of it connected properly to the motherboard. If still none, unplug it and plug it back afterwards.

I have now checked that every cable is connected properly on both ends and there is no change, fans will not power up, yet the lights flicker. Tried to unplug and plug them back in and nothing happened.

Ok lets troubleshoot a little..

First unplug all cable connected to your motherboard, power supply, HDD, SATA cable and DVD-Rom and even RAM. (except cable from your casing)

Then plug in only power supply cable to your motherboard (2 cables) and turn on your computer. If it beeping about three times plus all fans working, then put back RAM and see if the beep still there and observe the fan as well.

Still the same situation. Only flickering lights. No sound.

Then it's your power supply problem. It only have enough power to light up LED but not the motherboard itself. Consider buying new power supply for your desktop or if you have old computer or other computer that you use, try to salvage it for a while and try it on the faulty computer. If it's on, then most likely your power supply is dead.
