Don't keep changing anything. Until You do not
know the problem you are waisting money.Es i
understand You have a desktop and farther You
had a short circuit on the mother-board. So i su
spect the Power-Supply, but take it step by step.
1.Pow.Supl.can create shorts,can be intermitte
nt, erratic or You have a kind of sloppy mother-
board.Check the line voltage in the house it sho
uld be between 115 v.-120 v.
2.The CMOS and the battery has nothing to do
with the short, but it has with the IDE drives. Do
not tamper the jumpers.Set it up in the BIOS wh
en the computer starts to eliminate the long boot.
3.Try to run the computer first with the bare mi-
nimum disconnect everything, but the monitor,
keyboard,maybe mouse. Inside the computer
live only the Pow.Sup.,Mot.-Boar.,Hard-Drive,
Memory, pull all the other cards out from their
slots (surly if you have a video card leave it in).
If it does not boot try to boot it from a SYSTEM
DISK. When it booted one by one connect ev-
erything back until you find the defective part.
When You found the problem and eliminated it
only then should try to install WIN XP.
So first power,then components and peripher
als then Bios then software instalation.
Be avare not to overload the Pov.Sup.with to
many components, first when You try with the
bare esentials it works fine, and when you co-
nected everything it becomes eratic.
I fixed computers for many years i never saw
a defectiv CPU.
