hi guys, my problem started about a month ago, my pc wouldnt boot up. at the time i thought it was the processor because when it was removed it powered up, i had it checked and it now turns out that the processor is fine but it still wont boot up. i did a little more testing and noted down the post code display that is located on my motherboard and the problem seems to be with the 4pin 12v ATX cable. i am using an Abit AT8 32X. the post display is as follows.
ATX Cable attached, cpu also installed:-
(8.3.) - ATX power supply ready
(9.6.) - De-Assert cpu core voltage
(9.9.) - Complete power off sequence
i try to boot the pc but it switches itself off withing a second.
ATX Cable attached, no cpu installed:-
(8.3.) - ATX power supply ready
(9.0.) - complete uGuru initial process, AWARD BIOS takeover booting job
PC boots fine into POST screen although i have no display.
when the ATX cable is removed it obviously boots until post then shuts down, this is indicated on the POST code display.
I tested the 4 pin ATX cable with a psu tester and it says that it is outputting 12v, so do you guys think that the problem lies with the motherboard? if so any indications on what it might be? i dont want to fork out £100 for another one and it turns out its not that. also ill add that my pc was running fine for several months before this happened and i have made no changes since. thanks for your time, if you need any more info i can provide it.
