My computer won't start

by Damian555 / April 2, 2009 12:58 PM PDT

Ok well my computer won't turn on, it's an old dell dimension 4500. When I press the power button, it turns yellow, and stays like that, there's no noises or anything. This has happened twice before, it's like, my computer is working fine, but when I turn it off and try to turn it back on, this happens. The previous times it happened, I just left the power button yellow, and eventually the computer just started working within a few hours, but this time it's been almost a week and it's still not working. This is my system info:

Proccessor: Pentium 4 1.8ghz
OS: Windows XP Pro
Graphics: GeForce FX 5700LE
RAM: 768mb

If you are using Desktop, then try to clean your computer ( DUST ).
Take out RAM and re install after proper Cleaning.

What would be considered proper cleaning, blowing all the dust out?

Sounds like the old BAD CAPS issue.
by R. Proffitt Forum moderator / April 2, 2009 10:42 PM PDT

Type BAD CAPS on google to discover the most common cause for "won't start when cold" and "starts after awhile."

This issue degrades to "Won't start" in time.

The inspection for this one is VISUAL (you can see it) so it's easy enough to find out if this is the cause.

-> The good news is that even years later some companies are still changing out boards for free. Don't hesitate to call the maker if you find BAD CAPS.

I checked all the caps on my motherboard, some were slightly tilted, but besides that, no problems.

Picture please.

Another motherboard today showed up with this issue. The owner had done the inspection and we had to go over the details one more time. If you see anything other than perfection in the caps, it's a sign. Many owners fall in to a DENIAL loop that only the person who gets to the fix the machine will not fall for.

Tilted can be a sign of the bottom is blown out and it leans over.

Only with some great hi-resolution shots could I call this one but as it stands the symptoms and your posts tell me it's bad caps. You could try a new bigger power supply but that's up to you.

Is there any way to fix bad caps? And if you try to move a working cap, how far can it move around, like just barely from it's proper alignment or what?

The most tilted is like half of that picture, maybe less. Is it still bad?

If it was half as bad as that picture, it's still bad.

A picture could clear it up.
