I'm putting this computer together from bits and pieces and alls gone well except for some voltages on the motherboard -12.00v is -4.67v and -5.00v is -7.14v ? all the capacitors look alright they aren't bulging or anything it seems strange that its only the two negative voltages. I took the power supply out and it measured ok neg 12v is -11.67v and neg-5v is -4.67v. All the positives +12v, +5v ect.. are spot on? Where should I begin to look for the problem do you think? Would it be capacitors? I used speccy and cuipd computer spec programs to get the voltages, they where both the same!

Re: acer aspire m3100 motherboard
I should qualify that! Its OK when its booted up and going, its just getting it to boot up! When it is causing problems by not booting I can unplug and replug the sata cable on the motherboard and check all the connections and then most times it will boot? Thats why I thought it may be a cap making it go intermittent.HP P6-2203a desktop,AMD CPU A8-5500 with Radeon HD7560D,3.20Ghz. Radeon HD 6670.8Gb Ram.2TB HDD. WIN 10 64 bit O/S.

I'd be amazed if such a new PC even use -5 or -12.HP P6-2203a desktop,AMD CPU A8-5500 with Radeon HD7560D,3.20Ghz. Radeon HD 6670.8Gb Ram.2TB HDD. WIN 10 64 bit O/S.

If you don't have a cable in place of the blue or white on that picture, don't bother.
