New build ~ No power on...

jg623 · 11 Sep 2011 at 20:58

Hi,

Last week i made a post about what set up i should get, so i went ahead and ordered the Asrock extreme4 gen3, i5 2500k and 8gb (2x4gb) of Gskill RipJawsX

The build went fine (fully completed on Friday), after installing windows 7 everything seemed great. I was playing a game today and BAM, total shutdown.

As I'm quite cautious of overclocking i didn't mess around with any settings. Everything was running stock.
When i go to power on my pc, it powers on for a split second and the case fans spin, but nothing happens, (and it then loops this process) no error codes on the motherboard, Nothing.

What Ive tried:

PSU power supply test > everything is fine.
removed all HDD cables and tried power on > nothing changed
Switched both RAM sticks in slots > nothing changed
tested 1 ram stick > nothing changed
Removed graphics and sound card > nothing changed.

Which leaves me thinking there is only 3 things that it could be:

Faulty motherboard
Faulty RAM
Faulty CPU

Giving that everything was working for almost 2 days, (cpu temp was 30idle/40load) I think its unlikely to be the RAM and/or CPU, but i could be wrong.

These are the 3 components i cant test, i dont have an 1155 cpu/mobo or any other ddr3.

If anyone has an input, of what i should do next, that would be greatly appreciated. Your help is needed!

try taking the power cables out and putting them back, try taking out and reseating the graphic cards etc as well.

How did you 'test' the PSU, exactly? What PSU is it? Do you have another you could try?

Tried a CMOS reset, just in case the BIOS has thrown a wobbler.

What's the make / model of your PSU?

I used a power supply tester, something similar to this

I do have another PSU, but i wont be able to test it until im back home tomorrow after work.

I'll try reset CMOS, i have a Corsair AX850 Modular PSU.

I reset the CMOS > Nothing
I unplugged all the power cables and plugged them back in > Nothing

I'm at my wits end with this machine, it looks like i might have to RMA, the trouble is i don't know if its the board/RAM/CPU...

Had a simalar problem as u described and it turned out to be the motherboard.

I think it has to be. When i plug the 24pin connector into the psu tester, all the fans come on fine. Whereas if i plug it into the motherboard, it starts to do the loop process of powering on and off for not even a second.

Since i got the board through overclockers, i think the next step is to RMA it, its a real shame as well as I had high hopes for this board, looks like i fell into the bad batch category.Hopefully the replacement doesn't do the same, if it happens again i can assure you im not routing for Asrock anymore!

Thanks for your input, just out of curiosity, was this the exact same board or just similar issues?

Cheers,

Its a great board and asrock have come along way over the years. When can u rember asrock being recomended in a high end system? With millions of components produced theres bound to be faulty ones that slip threw the net. Good luck
