It's a brandnew 300W PSU, I don't think it's underpowered or faulty.
I've done a booting with just the necessary elements only, but that doesn't make a difference.
There's no post procedure
I've tried all the suggestions from the troubleshooting post, but we've already tried all those, and the computer still won't start.
My husband built a PC - like he's done several times before - but this time it won't work.
System:
AMD 2000+
512 MB RAM Kingston
K7S5A Elite motherboard
HD 30...
