Default buying caps

I'm trying to fix a Gateway pc with bad caps on the MB. I managed to
remove the bad ones ('Chhsi' brand name) and clear the holes.

I need (3) 1000uF 6.3v HM(M) and (2) 1500uF 10v WG(M) electrolytic caps.

I'd been believing the replacements would cost ~ $1 each. But the local
parts supply place has the 1000uF for ~ $2, and they don't have the
1500s. Radio Shack has the 1000uF 35v for $1.69, but they don't carry the
1500s. Can I use a different value in place of the 1500s? Radio Shack
does have 2300s.

I don't live in or near a large city. Any suggestions? I'd thought that
procuring the caps was going to be the one easy part of this project.

Btw, can I use axial, if they physically don't interfere with anything?
Do I have to worry about any other ratings and/or quality?

1st look here to see if they have a kit http://www.badcaps.com/kits/ if
not try Mouser http://www.mouser.com/.

Don't use crap radio shack capacitors or you'll be back in the same
boat you are now whithin 6 months. Don't use Xicon capacitors from
Mouser either. Cap kits always use the cheapest crap capacitors money
can be wasted on, don't use them either.
I always order from Digikey, www.digikey.com and use Panasonic FC
series capacitors which are high temp, high frequency and won't go bad.
There's a killing being made by selling $0.12 capacitors for $2 from
these other sheisters. Order these from Digikey.
1000uf 6.3v, part# P10199-ND $0.47 each
1500uf 10v, part # P10228-ND $0.80 each

Not just any 105C capacitors will do because you also need low ESR
(effective series resistance) or they'll likely run warm and wear out
earlier. Electrolytic capacitors rated for high-frequency switching
operation will almost always have low enough ESR. Get a good brand,
such as Panasonic, Nichi-con, Chemi-con, or Sanyo.

Btw, can I use axial, if they physically don't interfere with

anything?

Spacing is so tight on motherboards that there usually isn't sufficient
room since axials mounted upright have to be shifted over a few
millimeters, and even radials 1mm larger in diameter than the originals
may be a hard fit.

I'm having the same problem but with a p3 450 made by Packard bell. I
replaced one 1000uf 6.3v cap with 1000uf 10v, and 1500uf 10v with same.
I placed the motherboard back into the case and attached all the cards and
cables. And still the computer will not start. Anyone out there Have any
suggestions?

If it's a Packard Bell just junk it, they were worthless when new.

Apparently, the capacitors with the "X" on
top, bulge, & the ones with just a line..on top
leak at the bottom, & it's not always easy to see!
Heat up each of the two legs of the caps, one at a
time, & smell for "fishy" smell! It's the best way to tell
in circuit! Rono.
