My first guess would be bad RAM, but before you start replacing it, do
the following:

1. Clean out or blow out all the dust and dirt in the computer;

2. Remove all RAM chips and plugs, etc. and using electronic contacts
cleaner--It comes in a spray can; most computer or hardware stores have
it--clean all the contacts on everything. Re-install everything.

3. Check that all fans are clean and spin smoothly, particularly check
that your power supply unit is clean inside and the CPU heat sink is free
of dirt and "grunge."

4. Turn the computer on and see if it will POST, that is Power-on, Self-
Test. You won't need an operating system to do this. Most computers by
pressing the TAB will display what is being done. POSTing checks IO,
RAM, keyboard, etc. to see that all is well. If it finds a problem or
something doesn't work, you'll see it in the output.

5. If POST works and RAM is the problem, and you have more than one chip
of RAM installed, remove all but one, and POST again, exchanging chips
until the bad one is found. Install the good ones. Read the motherboard
instructions regarding RAM: It may not work with just one chip
installed. So, you'll have to adapt my instructions to find the bad chip.

6. If POST finds no error in the RAM, let us know and get other
suggestions. Also, if you know how old your machine is, and the
specifications on it, listing that, too, will help.
