Ok,
im at my service period in school right now and im having some trouble installing these new motherboards. they are microATX form factor gigabyte brand boards. We're using them to fix older systems that have the boards fried. I've just installed 3 that won't fire up, i've eliminated the possibilites of bad power supplies, bad power, etc. The fans will jerk, the "ram ok" LED stays lit, but the power led's don't come on and the system doesn't go. The pinouts for the power buttons are correct. I've gotten 2 other systems built exactly the same to fire up, but these wont'. I'm using a 300w Antec power supply, it worked fine on the other 2 boards, but these won't fire up. They can't be fried can they? otherwise the fans wouldn't even jerk and the "ram ok" led wouldn't be on. So, tell me, is it ok to use an ATX power supply with a microATX board? Do I HAVE to use a microATX power supply? From what I've read they're ony cheaper and have 1 fewer output modes than a normal ATX psu does. So am I wrong and I just got lucky with those other boards? Is there a jumper or fuse on the psu i have to mess with? Help!?
