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.
Your mobo capacitors may be full. Automatic shutdowns are commonplace when this happens because it is a motherboards way of making sure they don't overload and pop. They charge gradually over time, some more than others, depending on your mobo model and overall rig setup. Remove all cables from the PC and hold the power button in for about 30 seconds, release it, plug everything back in, then try and boot up. Let me know how that goes. Mike
yeh thnx mate... the pc was diconnected for about a month.. surely that would dicharge the capacitors? i bought a new mobo anyway and everything is running fine.. thnx for the reply mate =) oh and nice signature btw, made me laugh :chk:
