Computer turns itself off

I have a problem with my computer.
When I first got my computer I noticed that something were loose
inside it. I opened the cabinet and found out that the fan where not
attached to the motherboard. I called the dealer and he said just
attach it and all should be good. Well, I belived him. After a short
period of time the problem began.
No, from time to time, the computer just shuts down and makes a loud
noice. I have to hold down the powerbutton for about 10 sec. to get it
to stop. I've checked the tempatur on the computer, it shows about 50
to 54. I've narrowed it down to either motherboard, fan or
memorymodul. Because it seems to take longer time for the computer to
shut down if I don't open so much programs. But it I try to print a
photo, it shuts down at once.

Any ideas??

I had a simalar problem only last week, (which had been persisting for
about a month before I realised the problem!).

My computer ran very hot, it crashed when printing (and re-started),
and sometimes just stayed at the "Windows is shutting down screen" (I
just hit the power button after 1 1/2 hours), oh and Word would not
stay open for love, money or expletives!

My computer was a DIY one. Basicly the RAM was over clocked, not
intentionally, mind you, I must have bought the wrong speed! It was
running at 133MHz rather than 100MHz. it coped just fine for 5 months
then I had the above problems.

I bought twice as much DDR RAM (rather than SD, if I have to spend
money the its an upgrade im getting!) and it works like a dream!

Much faster (around 25%) and no crashes!

I'd wager on a memory problem, it miht not have been over clocked, but
one bad bit in the stick and you can have those kind of errors and
massive overheating.

All of this is familiar to me. My computer just stopeed working one
day. It would boot up, let out a repeated beeping sequence, and repeat
until I pulled the plug. Upon investigation, a light on my motherboard
called OVER was on. Checking the manual, this was the overheating
mechanism. I checked the bottom of the heatsink, and discovered that
most of the TIM was gone. I put the computer in the shop, and that is
where it has been for 10 days now. Try getting a new heatsink, or at
least lap the old one. Then, apply Arctic Silver thermal compound.
That should help a little. If not, try installing more case fans. By
the way, my computer suffering overheating is an AMD Athlon XP 2000+
with default heatsink, custom built.

If a CPU runs too hot, it will fail, sometimes resulting into severe
damage.
The fan/heatsink needs to be securely attached onto the board with a
thermal interface between the Heatsink and CPU Core.
A modern high-performance CPU can be permanently damaged in less than
10 seconds without proper cooling.
If Thermal Compound is NOT used the computer is likely to fail and
shutdown
due to a lack of heat dissipation.
