The computer powers on but nothing happens after that (no beep)
1. This may be due to the addition of new hardware that is overtaxing the power supply. Remove the last hardware component installed and check again.

2. A defective hard disk or one that is not plugged in correctly: Check the power cable to the hard disk. Sometimes it may not be fully plugged in. Check the hard disk on another system.
