Hi I bought a "gaming bundle" from ocuk this week which has worked perfectly until now. I had it on this afternoon left it for a few hours came back and it was off (I guess it went into sleep mode) anyway when i came back I switched it on now all i get is, it fires up for around 3 seconds and turns off for around 4 seconds and then it will come back on for 3 and this just repeats. I have tried switching the PSU off and unplugging it. I have also opened up the system for any loose connections and then tried again with just the monitor plugged in the back and the power cable and still just does the same. Any ideas?

Info:

Gigabyte Z68XP-UD3P Intel Z68
HyperX DDR3 4GB x2
Asus 560 ti CU II
i5 2500k overclocked to 4.6ghz (overclocked by ocuk)
Antec 850w PSU
Crucial 64GB SSD 6gbs
WD 500gb Sata II
Corsair A50 cooler
Creative X-fi platinum sound card
Antec 900

Try using just the basic parts needed for it to boot up.

A single RAM stick, remove the GPU and use the onboard if you have a HDMI cable?

Remove the sound card.
 
By removing all the ram and just using one stick would that do anything to change the bios? I just don't want to do anything that could void the warranty that ocuk give on there bundles.
 
Sorry just to check by removing that battery would't that wipe the over clock that ocuk have done in bios cause i know if i screw around with any of the bios it voids there 12month warranty.
 
I think i will just wait til tomorrow and call them, it's there problem really.

Thanks anyway if i built it and it had no warranty i would give it ago.
 
You have sleep enabled, you need to go turn it off. I had this exact same issue with mine, came back after few hours and id switch on, it would turn on for two seconds then back off. P67/Z68 and sleep mode seem to have issues, thought that was only with Asus boards though.

Switch it on, then quickly hold the power button when it comes on. That should turn it off (Hard shutdown), then simply turn back on. Thats how I got mine to turn on. Then it'll resume windows, you'll have to wait for it, it might get to a black screen, give it like 5 minutes atleast.

I have tried, held the power button on so it stopped trying to start then turned it on and left it for 10mins while it just powers on and powers off and so on.
 
Oh right, well when you hold the power button it is meant to turn off, then when you turn it on it is meant to turn on as normal. Dont leave it to power on and off mate.

OCuK usually have the overclocking profiles saved so I dont see why removing the battery would be an issue.
 
I spoke to ocuk this morning he advised me to remove battery for 3 mins and it done the trick, I will be turning of sleep to make sure this doesn't happen again, thanks for your help I know that's what you said to do but just wanted to check i would not void any warranty.
