Default Laptop keeps on powering off

Hello All;

I have read numerous threads about laptops powering off immediately after use, but I'm at a point where I am about to give up on this job.

It is a HP Pavillion dv5000 with Win Xp Home. Initially, the issue was that laptop was making a humming noise through the audio ports. I took the laptop apart to check for any issues /shorts/grounds but all looked ok.
About 3 months later the same customer came to me and said that now the laptop won't stay on more than 5 minutes, it keeps on powering off. I have booted up in Safe mode and it still powers off so i think its a hardware issue. Also, I did feel that the bottom of the laptop gets hot very quickly, actually within a couple of minutes so I know its overheating somewhere. I take it apart and blow out all the dust bunnies, but still powers off. I added another CPU fan, switched up the RAM, took out the CD/DVD Drive and just booted up with nothing but the HDD and the fan, but still same issue. I am ready to deem this a motherboard issue, however is there anything i have missed? I also did check components and checked the solder to ensure they are all fine..in what I can tell it looks good. PLEASE HELP
