Hi Peeps,

Ive had my i5-2500k sandy bridge overclocked at 4.5ghz since 2011. Everything was going swimmingly until yesterday!

On pushing the power button PC goes to boot up but then cuts out after about 2 seconds and then goes for another start over and over.

Ive tried disconnecting everything but PSU and Motherboard/CPU with 1 RAM stick but it still wont boot. Tried reseting the Gelid Cooler with Arctic Silver 5 and have also tried a different PSU (Corsair CX430) and it does exactly the same.

This looks like CPU failure? or Motherboard?

The system is as follows

Gigabyte Z68XP-UD3 Intel Z68
Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit
BeQuiet Pure Power L7 530W '80 Plus' Power Supply
Gelid Tranquillo


What do you guys reccomend, is there a motherboard to fit the sandybridge anymore, can i still get that processor?

Or shall i just build a new system.

Cheers for the replies in advance, when i built this system it was from the great advice on this forum.

Cheers again

Nick
 
have you tried a clear cmos option yet?

disconnect the PC from the mains, remove the battery and leave it for 30 mins plus, some say a few hours. then give it another try
 
fair enough, guess Im used to people using pcie cards and very rarely using on board gpus by default.

maybe why the screen doesn't even light up if the cpu has gone.

did the cpu look ok when you re done the cooler and thermal paste and did you re seat the cpu or so the cooler?
 
Hi,

Yeah its just sort of a work PC, i didnt take the CPU before just repasted the cooler.

Ive just taken the CPU out, looks fine no damage. Ill reseat the cooler again and go for a start as the CMOS battery has been out half an hour now.
 
don't suppose you have another cpu you could try or one you could borrow from a friend?

then that would confirm if the CPU is at fault or try your CPU in another PC and see if the fault follows the CPU
 
can see you have said you have tried with 1gb of ram in, how many sticks of ram have you got? have you tried each of them 1 at a time to see if it boots?
 
had 3 sticks up until recently 4GB each all kingston, ive tried variation of them but to no effect

Cant think what else can do
