Greetings Mike..

Other than the Preventative Maintenance (PM) factor that the other 
gentleman mentioned, which is always a good idea, you're probably 
going to discover that you've got a hardware issue that probably isn't 
fan based. Of course, if you're careful against ANY possible short 
circuits, with the case opened up, it cleaned up and a small fan 
blowing across it, power it up and see if it again shuts down. If so, 
this is likely a hardware anomaly and not something that will be easy 
to find or fix. Why not? For one thing, due to the fact that it's 5+ 
years old now. In laptop/PC terms that's [at least] a couple of 
generations of hardware. Regardless, due to surface mount technology 
employed these days, it wouldn't exactly be easy to repair even if you 
knew exactly the component that was causing the issue. Of course, 
that's not to say that it may be more than one component.

Laptops are a different breed when it comes to the actual electronic 
components themselves. It's not quite like the standard PC 
motherboard. I've now had experience not only sending in a motherboard 
for repair which I later got back and the motherboard I'm using right 
now which is a different motherboard. In the case with the existing 
motherboard I'm using now, the issue was polarized aluminum 
electrolytic filter capacitors. Unfortunately, they were the infamous 
GSC Taiwanese brand where the electrolyte was [supposedly] stolen and 
not correct formula to boot! Result, the electrolyte dried up and the 
capacitors required replacement. Symptoms were a constant resetting of 
the motherboard. I invested about $10 worth of electrolytic capacitors 
and a good deal of time and effort to go through the motherboard after 
it was initially discovered that the capacitors were, in fact, the 
issue. Incidentally, in this case it was over 30 filter capacitors and 
they were NOT surface mount components but 3mm L.S. radial lead.

With the number of sales going on these days with laptops, consider 
the alternatives. But also consider an extended warranty IF you 
consider a newer laptop. A good friend has had his Fujitsu notebook 
back a couple of times now. The last time they got the notebook 
working but not the USB connection which constantly showed a short in 
a pop-up window. After returning it a second time (still under 
warranty) all is fixed and working as it should be. If he had to pay 
for all of that...

Good luck!

Cheers,
Mr. Mentor

Right fellas,
I have a Compaq Presario V4000- about 5yrs old now & it recently kept
shutdown without warning, I rebooted & guess what...it shut down
again.This kept happening whilst streaming.
I started to read up & soon became aware that other people were having
the same problem.
Is your laptop hot to touch on the top left hand corner? There is  a
little alan type screw underneath that houses a cooling system..open
it up & take a look, Mine was clogged with dust about 3mm thick & I
managed to hook it out without a problem...my lappy has been running
fine now for the past 8 weeks!! Spend �10 on finding a screwdriver
that fits mind you! (B&Q) Hope this may help!!!!
