Hey, I recently purchased a new motherboard, ram and proccesor from OCUK. I have installed everything into my case and plugged in the power etc. Now when I turn on the power, the CPU fan spins and the "phase lights" on the board all light up but then after a few seconds it just reboots and does the same thing over and over. It happens so fast that the only way I can actually switch off the PC is by the power supply.

I have checked the CPU pins + motherboard pins and got somebody else to double check for me that they were not even slightly bent and they look perfectly fine. So I am wondering if there is anything else that may be causing this problem?

Graphics Card: Nvidia ASUS 460 GTX 1024mb
Power Supply: Antec 850w
CPU Cooler: Corsair H90
Case: Antec 300
Motherboard: Gigabyte P67-A-UD4-B3 INTEL P67 (SOCKET LGA1155)
Memory: Kingston HyperX Genesis Grey 2x4GB DDR3 1600MHz
Proccesor: Intel Core-i5 2500K 3.30Ghz (sandybridge) Socket LGA1155
 
Had this problem last week when i built my first pc. Tried everything then found it was the the Ram (same brand as yours)

Try unplugging 1 ram then trying it, if it still occurs, try replacing it with the other ram.

For me it was 1 faulty ram stick, just RMA'd it today and OcUk have now shipped my replacement
 
Hi there,

I bought a similar system nearly a year ago, here is my thread, hope it helps!

they advised me to try certain things and eventually told me to rma it. Did so & OCUK were great about it!
After that i did this post, dunno why i never carried on with the original post, beer me thinks lol.

Thank you, im gonna give all of these things a try from your thread and see if I have any luck. Unfortunately im busy most the weekend though so to fit all this time of fiddling about into my schedule is gonna be a huge pain in the ass. Definately sounds like you had the same problem as me though, but I have never got the PC to boot ever. The screen is black constantly it doesn't get far enough to send it any signal etc.
 
Ok so I have tried

Booting with no power in the graphics card, still didn't boot.
Booting with only 1 stick of RAM connected in slot 1 (tried both RAM sticks)
Powered it up about 20 times in a row and never got any signal on the screen.
Reseting the CMOS

Still won't work =/
 
Have you tried doing this out of your case, on the motherboard box? Apart from that suggestion I can only advise you to go to the Uk Gigabyte forums and make a thread there. Some of the people on here have a great deal more experience than me so hopefully they will help you sort it out.
 
You definitely got your 8 pin CPU power plugged in? Sounds silly but you never know. Sounds like CPU is not getting power or memory is not running correctly, usually the memtest on asus boards sorts this but not sure on gigabytes.
 
Ye the 8 pin ATX cable is definately plugged in. I wish I had a speaker clip for my board to be able to hear the beeps as it try's to boot, although I don't even think it would last long enough.

I haven't tried it outside the box no, but I don't see my case being the problem due to I have had my case for years with several different motherboards and it's always been fine. But when I get time I will give it a go.

I remember a computer a while ago i fixed and it was due to viruses. Managed to check that?

Heheh, he can't even boot the pc.

If you have another stick of RAM from a different brand? I had this problem with motherboard about 2 years ago. It turned out that for some reason the motherboard did not like the RAM i was using. New stick and it was fine.
 
I can't boot the PC so it's nothing to do with a virus lol.

Still can't get it working though :( Keep randomly giving it a few try's here and there to see if it will randomly work but no joy!
