The best way to diagnose a problem like this is to do it in a very methodical way. The following steps are a practical guide to isolating the cause of the problem.
1. Swich off the power but don't disconnect the power lead. You will need the earth connection in the power lead to discharge static electricity from your body.
2. Discharge any static electricity in your body by touching anything that is earthed e.g. the computer case if it is metal or if it is plastic the nearest water pipes. Don't build up static electricity in your body by dragging your feet on the carpet etc... It is always best to wear a static dischard bracelet, but I assume that you probably don't have one.
3. Open the case.
4. Swich on the power and power up the PC and observe if everything appears to be working normally. e.g. Power suppy on; fan spinning; LED's on main board on; any other visual indicator lights that should be lit are lit.
5. If everything seems OK power down the PC and swich off the power at the wall socket.
6. Discharge your body static.
7. Remove each board. If you have White Spirits clean the contacts with the spirits and a cotton-bud. Blow-out the slot. Reseat the board and make sure that it clicks properly into place.
8. There are many types of memory (RAM) configarations. Make sure that whatever type you have is securely seated in its retainer. Don't remove the RAM just press it back into its seating.
9. Starting at the top-left work your way around the main board in a clockwise direction by unplugging and then immediately replugging all connections. WARNING: Not all connections are tabbed and it is possible to reverse connections, therefore always unplug and replug immediately.
10. Discharge your body static.
11. Press firmly on the top of the Main Processor ensuring that it is fully inserted into its seating.
12. Switch on the power and power up the PC.
13. If you still get absolutely nothing, and everything looks OK, then the most likely cause is that the BIOS has died.
14. If the BIOS is dead refer the problem to your PC supplier who will give you the best advice for your particular make and model.
