can a psu make your computer not boot but run

[Fanatic4Christ]

okay well i tryed the psu from my dell and it worked on my new motherboard, but i try to hook up the old one and everything turns on but seem's to run extremely slow, like the fan's and stuff, also the harddrive doesnt boot, how is this possible from just a power supply?

It's either

A) Simply not powerful enough to run the machine completely
B) Some of the cords are bad
C) It's defective

well it was previously shutting off, its not defective for sure its not A either because it ran it before, so mabie its b? (had since like 2001) i already have another psu on the way so im hoping so badly that its that because that is the second thing that i buy to try to fix my computer, haha thanks

Uhh, well, I noticed when I didn't have some of the cords into a few parts of my PC when I installed my new 400W, the stuff would work odd, the GPU's fan would work, turn off, work, and it wouldn't really start well, I just made sure everything was tight in there and it worked then. I dunno if that's your problem lol, you could try it but I've never heard of anyone as careless as me and not pushing the cords in enough but, if you've had it since 2001 I'd get a new PSU anyway, I'm surprised my PSU I had since 2004 that came with my machine was still working until I got a new one. But 2001? Dang. I'd just wait for the new PSU.

I've never actually seen anything in High Definition. But, it's good you have something to occupy yourself with.

What do you think the "HD" in HD 38xx stood for?

You can read more about HD here: ATI Radeon™ HD 3800 Series – Overview

Your power supply is definitely bad. It may have a bad capacitor or some other problem that is not allowing it to fully output the needed power.
