Hi All,

A friend of mine recently put together a computer for me. About a month a go it stopped booting up properly. The motherboard wouldn't post and would hang on LED error 62 and the fans would start running at max speed.


Figured this was a faulty motherboard and RMA'd it. The replacement arrives, I instal it and it works for a few hours. I shut down as normal and the next day when I attempt to boot up it gives me the same error and won't post!

I tried everything from single RAM, in different slots, different GPU, onboard graphics, different PSU and no luck.

Thought I might've just been insanely unlucky so I picked up a THIRD motherboard (this time a different brand/model) and it works, again for a few hours. Shut down as normal last night. I hadn't changed ANYTHING in the bios, no CPU or GPU OC, nothing. Boot up this morning and the motherboard won't post, hanging on error 69 with all fans on max speed. It's like something in my system is killing these motherboards beyond repair.

Does anyone have any ideas what this strange pattern suggests?

I'm running a 750w bronze-rated corsair PSU, 3570k CPU, 8gb 1866 corsair vengeance RAM, AMD R9 280X 3GB GPU, and currently Gigabyte SKT-1155 Z77X-UD3H Motherboard

The only thing I haven't been able to swap out is the CPU. I don't have another one to try. It's just odd that the entire system works flawlessly for a couple of hours (even did some gaming) and then NOTHING. And swapping for my other PSU doesn't solve the problem. I though maybe my 750w Corsair PSU that I'm using is maybe causing permanent damage to these MOBO's? I don't know, I'm not very tech savvy.

Many thanks for any and all responses.

Sorry I forgot to explain that I cannot even boot to BIOS. The motherboard hangs on error 69 on the LED physically on the mobo. No signal gets sent to my monitor so I can't access the BIOS. I've tried booting with just one stick of RAM, in different slots, and I've tried my old 1333 RAM, aswell. Also tried clearing the CMOS but no luck.
 


If you can, try getting hold of a different CPU as it sounds to me like its dead. The fact that you are now on your third board and still having the same issue, even after switching out the PSU and the RAM means that it's likely that your CPU is pretty badly knackered.
