PC NOT turn on, ... Complete 'Dead?'

[3c273]

My first guess is alwaus the power supply. Sniff around the fan grill next
to the power cord. Does it smell like burned plastic?

A fan going out will not cause a computer not to boot--sounds more like a
power supply failure. Do you smell an electrical burning smell? I assume
from your comments that there are no noises or lights when you power up. If
so, there is probably serious hardware damage and warrants a look by a
professional.

Get it fixed. Seriously, take it to a repair tech and let him tell you what
it needs. It sounds like the PSU but don't try to second guess a good tech.

Hi:
When I tried to look at pictures by inserting a CD, PC got a terrible noise
which is similar to 'burning something' incide, one of fans or even motor?

What's puzzling me is that until this happened, the PC with XP has been
running REALLY good.

Any clues on this, whether the PC got 'dead' or what's else, ... would be
truly appreciated.

Thanks,

Thanks all for the responses and concerns. I truly appreciate all for
this issue to figure things out.

As to 'burning smell,' it's more likely 'plastic' burning smell, but
still a shock, then my nose is not really functionable at this moment.

There are NO light nor noise upon trying to turn on. First, I can not
turn on the PC at all, after I pushed a button at the front panel to
shut-down
the PC in a hurry upon having heard a terrible noise coming from bottom
part of front panel of the PC.

The PC is about 5 years old, but until this happened, the PC was
surprisingly running good.

That's what electronics do. They die real fast. All it takes is one
component to die and it can fry the entire system. Like a tire blowing
on your car. It just wears and one day 'pop' it blows. "It was
working before!?"

Unfortunately, ... yes, smells like something inside burned.

What do you think I need to do the next?

Thanks,

It is almost certainly your power supply. If you are not handy with these
types of things, you should probably have a professional take a look at it.
That being said, a power supply for an older machine should be relatively
inexpensive and they are not that difficult to install if you feel
adventurous. Unfortunately, there is no way of knowing if your problems go
beyond the power supply. I guess it all depends on how much time/money you
want to throw at this machine.

Wild replacement of parts is a solution?. Better informed would
have an answer in but two minutes. Standard procedure was posted in
"When your computer dies without warning....." starting 6 Feb 2007 in

In your case, most important numbers are voltages from purple and
green wires - all numbers taken both before and when power switch is
pressed. Others previously ignored this recommendation, bought a new
supply (on wild speculation) and eventually had to start over again
doing this less than two minutes of labor. Better is to first
identify a failure before replacing a suspect.
