I have a old mother board P5L-MX with built in gpu intel 950 .Everything was working fine then one day it would not post no beeps or video .I took it apart  and put one piece at a time back in and there is still no beeps .I would try and boot every time I added a part .Lights and fans start .Would it be the cpu which mine is a intel celeron D 3.33ghz . I have seen some place there is something about caps that swell on the mother board ???and if there is where about's on the board are they ??. Also I change the ram hard drive cables cleared cmos .Thanks for any info on this

It's most likely the cpu, motherboard or power supply. This is assuming that you've switched out the ram and have tried different slots with only one stick of ram.

Swelled caps are pretty easy to spot. If they aren't flat on the top then they're failing, if they have residue on the tops then they've probably completely failed. These usually fail closer to the CPU.

Here's an example of a dell that I looked at yesterday that has bad caps:

Yes you can if you have good soldering skills and the proper capisitors, understand how to do it and have the proper tools.
I would highly reccomend you just replace the motherboard with something better if possible because replacing swelled caps doesn't always solve the problem.

Replacement with the same size part would be enough but there are two causes.  One, too much current being drawn from the circuit, or Two, they are manufacturers defects.  Either one, replacement might get you back in business.  If they errupt again, larher caps, with a little higher voltage and more capacitance,  Might even find some rated higher but in a taller can to fit in the same spot.

A bad video cord or a non-functioning monitor, would also lead to no beeps at POST, fans and lights coming on and no apparent output from computer (just as if it wasn't working).

 

Before you start re-soldering stuff, see if you can get your hands on another monitor and video cord, and check to make sure it's not a video issue.
