It's possible to have only the +5 of the power supply work, and
produce something like you're seeing.

Power supplies are easier to test. And replace. A standard ATX power
supply should work, but if this is a micro desktop, it might not fit
in the case.... However, it would power the machine, you could borrow
one from a p4 class machine and see if it does the trick (acutally, it
just needs the extra square connector thingy AKA the 12v rail). Then
order the proper PSU from Dell.

However, given that the machine is one known for bad motherboards,
this is NOT a safe assumption.

Da manuals.

Thanks guys
I've got hold of a second hand working power supply that fits. I'll
try it tonight and hope that will fix my problem.

If, worst case senario, it ends up being the motherboard, is this a
cost effective repair? Or are the motherboards expensive to replace?

Cheers Mark


It's cost-effective. But if it is the board, you'll want to call Dell as
they may replace it FOC (it was part of a large recall.)

Beyond that, they can be found on ebay I'm sure - though I haven't looked
recently for that model. Purchasing the board will be much less expensive
there than from Dell.
