I also had that same problem with my old computer...

What happens:

1. turn on computer
2. mouse & keyboard switch on
3. computer runs start up but then says faliure
4. screen goes black
5. no bleeping or making deliberate noises
5. computer, mouse, keyboard and moniter stay on
6. ocasionally after resetting computer boots but after 2-5 minutes goes black
7. insides are clean
8. all fans, lights ect. inside computer work fine
9. quite humming like when hibernating
10. cannot boot in safe mode, from disk or last succsefull boot

Posible problems:

1. Loose connection
2. Hard drive faliure
3. Prosessor faliure
4. Chip damaged
5. over heating

Identifing the problem:

1. the hard drive should be softly vibrating - if not you need a new hard drive
2. the prosessor should be softly vibrating - if not you need a new prosessor
3. the prosessor should not be hot - if it is then you need a new prosessor fan
4. take apart and re assemble computer tightening all conections and looking out for damaged wires - replace any damaged wires
5. remove the chip, test your computer with the chip from a working computer.

testing the part:

remove the part that you think is the problem and replace it with the same part from a working computer - if the computer now works buy a new one of the faulty part and replace the old one with it - put the part you used for testing back where it came from - if the computer still dosent work - take it to an expert or buy a new computer.

... sadly it looks like you have a serious problem
