Advice on upgrade after possible CPU Failure

[npfman]

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

Hi,

I only use the onboard HDMI output, the screen doesnt even get a change to light up before the PC resets.

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.

Same again after CMOS out for 30 mins and cpu/cooler reseated
