Hi everyone,
I built my new system a couple of days ago and has all been fine until last night when i tried to power on. I pressed the on switch and the fan and LED's came on and then immediately went off. This happened a couple of times and then it worked fine. Tonight however, it was switched on for 3 hours and ran with no problems until i put it into sleep mode. When i came to boot it up again i had the same problem as the previous night except this time it would not boot up at all.
My spec is:
Krypton Z68 590i Intel Core i5 2500K 3.30GHz @ 4.40GHz Overclocked Bundle

Gigabyte Z68AP-D3 Intel Z68 (Socket 1155) DDR3 Motherboard

Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit

EVGA GeForce GTX 550Ti 2048MB GDDR5 PCI-Express Graphics Card

Antec TruePower New Modular 750W '80 Plus Bronze' Power Supply

Microsoft Windows 7 Home Premium SP1 64-Bit - OEM

Zalman Z9 Plus Tower Case with Fan Controller - Black

Seagate Barracuda 7200.12 1TB SATA 6Gb/s 32MB Cache - OEM

TP-Link 300Mbps Wireless N PCI Adapter

LG GH24NS70 22x DVD±RW SATA ReWriter (Black) - OEM

Please can you help, thanks in advance.
 
I think the best place to start is by unplugging any peripherals (e.g. Keyboard, mouse, monitor...etc...) and see if that makes a difference.

If not, try the same with hardware, unplugging bits one by one and seeing if it will boot up after each removal. Start with dvd drive, then move on to RAM/video card, then hard drive.

It might also be worth trying a different PSU if you have one available.
 
Hi Roblam,
I have tried doing what you have suggested and it i still doing the same thing as before. Unfortunately i don't have another PSU to try.
Do you think there might be a fault with the PSU?
Thanks for your advice.
 
Try doing a CMOS reset, I recon the overclock has failed and the board is trying to revert to default settings.

Once you have done this, pop into the BIOS and hopefully there is a saved profile which you can load and revert back to the original settings.
 
Yeah, from what you've described it does sound like it might be the PSU that is the problem.

Can't be 100% sure though unless you try a different PSU in your machine, or try the 'problem' PSU in another machine and see if it has the same issue.
 
Hi all,
I have took out the peripherals and done the same with the hardware and it is still doing the same as before.
I'm just wondering before i do the CMOS reset will it delete the overclocked profile or will i simply be able to load it again if the reset fixes the problem?

Click to expand...

The profile should be still be saved in the BIOS of you to load once the CMOS is reset. Only doing a BIOS update will delete the file.
 
Hi, clearing the CMOS seems to have solved the boot issue.

I was faced with this message after booting. Obviously I can reload the overclocked profile in the BIOS but is it safe to do so? There must be a reason for the problem in the first place? Thanks for your help so far.

You will be safe to re-load the Profile, sometimes the board throws a wobbler, mine has done once or twice in the past, redone the Overclock and and all has been well.

If t happens again, stick a note on the customer forum and they might be able to do some pointers over the forum.
