Hi guys

Recently bought a "Titan Spinosaur" Rig from OCUK, everything has been great with it, however I have noticed when turning it on sometimes, it does not post to windows... I get a little cursor in the top left hand corner of dos and it hangs there.., sometimes when turning it on it turns itself off after like 5 seconds and then turns it self back on again. I have to turn the pc off and on several times for it to boot into windows (I can then use it fine and game on it as long as i like even leave it on all night and go to it next day).. if i reset it from windows when loaded it will boot straight up into windows again.. I have done some modifications to the pc such as upgrade the hardware in it etc but it started doing this from when it was standard..

Spec is as follows:

Case: Antec 300 Case with Purple LED Fans
Power Supply: OCZ ZS 750w PSU
CPU: Intel Core i5 2500K 3.30GHz @ 4.60GHz Sandybridge CPU
Motherboard: MSI Z68A-GD65 Intel Z68 (Socket 1155) DDR3 Motherboard ** B3 REVISION **
Cooler: OcUK H2 Flo CPU Cooler
RAM: 16GB DDR3 Kingston HyperX Genesis 1600MHz Dual Channel Kit
Hard Drive 1: OCZ Agility 3 60GB 2.5" SATA-3 Solid State Hard Drive
Hard Drive 2: Hitachi Deskstar 7K3000 3TB SATA 6Gb/s 64MB Cache 7200RPM - OEM
Graphics Card: HIS ATI Radeon HD 6950 IceQ X Turbo 2048MB GDDR5 PCI-Express Graphics Card
Graphics Card 2: HIS ATI Radeon HD 6950 IceQ X Turbo 2048MB GDDR5 PCI-Express Graphics Card
Sound: Realtek 7.1 Channel Sound (On-Board)
Optical Drive: LG DVD+/-RW SATA Drive

I am running it through a 50" plasma tv..

Any ideas on whats causing this?
 
One thing perhaps to check is if the board is looking at a different drive, do you have any usb keys in. (even though it should show a error)
 
Next time it comes on for a few seconds and then turns off and on again, I'd just bob into BIOS and check the overclock as my mobo seems to do this after I change voltage settings in BIOS.
Just a thought.
 
Still no joy its doing it intermittently.. i loaded the default overclock profile from overclockers and it still does it although a lot less? i think its possibly a voltage issue could this be possible?
 
I was going to suggest RMA'ing it and having Overclockers sort out the problem as it is probably something as simple as a tiny setting in the BIOS, but as you have upgraded the hardware I'm sure you will also have voided the warranty.

What I would perhaps suggest is going into BIOS and loading I think it is fail safe default settings. If it stops doing it with these settings then you will be able to diagnose it as a problem with your overclock and then go through it step by step. And yes unfortunately Overclockers do make mistakes with overclocks, as they sent me a pre-overclocked bundle that was unstable, but sorted it in a few days.
