To boot the Dimension, I have removed the side cover and use a fan heater to warm it up. After a few minutes the heat causes the coling fan to start and then the computer will switch on via the on/off button. This has to repeated whenever it is switched on.
Do you reckon the power supply unit could be the culprit.
The computer is 3 years old and is used in our house which is at normal house temperature.
If you want to do it at the local level just find yourself a 400w ATX power supply that you can take back after testing (your machine may require a specific power supply and the ATX may not be mountable in your PC).

Make sure u can open the casing well to expose the interior parts without causing any damage. Then by close look at the processor area , that is where the heat sink is located. Normally the dell dimension 2400 has a green channel shaped structure that acts as a passage for the air that enters in and out for cooling the heat sink. It has a locking parts that slides into the casing back by slight pressing to the back of the casing just behind the processor area, be so observant to notice the locking parts. then the fan is just fixed behind that green " channel like" and its fixed on the rear side of the casing,
That's because it heats up more easily and faster, which usually makes the fans spin faster and results in being noisy. Have you ever cleaned out the interior of the computer? If not, or if it's been awhile since it's been done, then buy some canned air for dusting electronics, open the side of the computer case (while it's not powered ON), and blow out the fans and the heat sink. If you get alot of just clogging up the heat sink, then it will not dissipate heat correctly; which results in the fans running more often. It that doesn't help any, then I would try to figure out if one of the fans is making alot of noise because it's going bad. You can find replacement fans on ebay, or at local electronics\computer shops.
When you first turn on your computer, start pressing the F8 key about once every 1/2 second until you get to the boot menu. From there, select "Safe Mode" or "Safe Mode with Networking" (if you want to transfer files via network connection). The rest should be pretty self explanatory.
