You should match the caps. the 10v may be too low. I normally go up on the uf's and keep the voltage the same. But the pc may not sure on since the voltage is low. Also check your onboard cmos battery.
 
Fixed

The computer is working fine.
I had to use these to fit under the heatsink area.
Im going to order the correct size to fit under the heatsink..
I mention the fix because that will fix the computer..
but its tight under the heatsink,so i used these to get it up and running while
i wait for the correct caps..Its been on for 5 days now..
 
Build your own PC next time. :)

Dell uses crappy generic parts in their PCs. I bought one of their "high end" ones years ago and it always has issues. Built my own recently for half the price of a DELL and about 5 times as fast.

That's the absolute ass backwards thing to do. ALWAYS match uF and go UP on voltage, NEVER down. Unless you enjoy destroying other components in the circuit.

That may not always work. If the cap is a pullup cap, fine. But if it's in a RC, RLC, timing, or frequency filter circuit changing capacitance can really mess things up. When in doubt match capacitance and increase voltage.
 
that model of dell is known for bad caps i have seen plenty, best bet to get the right caps is from badcaps.net thats where i get all my caps for computers from just finished recapping a dell the other day and will be doing my imac soon

This statement is absolutely true. Higher voltage cap OK, different uF, bad news!

Be prepared to release the magic smoke.
 
Now that I seen what I wrote... I do appricate the corrections. I don't know what I was thinking that day. Too much stress from work... too many things on the mind.
 
I don't know anybody these days that isn't stressed out of their minds. I guess its one of the signs of "change" that we are going to have to get used to. ;)

I've fixed a few motherboards and removing the caps legs always makes me nervous. You have to apply just enough heat to release them, but not so much that you lift a trace or mess up the four layer board. So far I've been lucky.
 
Caps

Thanks for Everyones comment!

I knew i'd get some flack, for using a 10v cap
but its the shop computer and the secretary was panicking!!
I had to do something to get it going..
I'm still waiting on the caps and it is still working fine!
I normally match the uf and voltage,because i have most size caps instock!
 
if you guys want some interesting reading check out badcaps.org.. the forums over there aint too bad..

for pc ,laptop repair, lcd monitor repairs, lcd/led/plasma tv repairs(youll see me there alot) its cool..

dont worry, im not going anywhere anytime soon.
