Evening all my new system has been running fine for a couple of weeks until the other day! The problem is when it boots up the dial on the motherboard goes from 19 to 15 then stops and then the system switches off then back on!

Yesterday evening after about eight attempts i pressed the cmos or rbt button on the motherboard and it was fine and away i went no problems playing games etc then this morning it switched on fine no problems then tonight it wasnt having any of it, i have tried all cable connections hell even taking the battery out the motherboard nothing is working.

I dont have access to other parts either to try out and my system spec is:

i7 4770k stock clock
gigabyte sniper z87 m-ATX
8gb kingston hyper beast 2133
ocuk tech labs 7970 gpu
corsair rm 850 psu
watercooling and custom braided cables

Running windows 7 32bit due to upgrade to 64bit on wednesday

Any help would be great as i am not a great problem solver

Look in the motherboard manual and see what the boot code display means. Intel based motherboards do this "double start" if they've lost power at the mains or PSU. They interpret it as a failed boot due to bad settings and do a restart to check the BIOS settings.

Looks in manual the two codes displayed mean:

15- pre-memory north bridge initialization is started

19- pre-memory south bridge initialization is started

on boot up it goes 19 then 15 then after a few seconds off then on repeats process!

sounds like you have a bad BIOS or Gigabyte boards have two BIOS and if one gets a bit corrupt or the settings are not quite right then it does this. Expensive boards have the option to view the different saved bios in the BIOS menu so check that and remove any saved bios. Also do a force bios backup so that both BIOS are the same. I think you can do it with ALT and F12 when you boot up.

Thankyou for the reply thing is it wasnt even getting to the point where i could enter a command it literally went 19-15 and off.

I have dismantled my whole system tonight and going to speak to ocuk about sending it back on the advice on another forum member shame really
