My desktop sounds like its on but the monitor, keyboard & mouse don't seem to also when I press the power on button after a little while it beeps about 4 times.
DELL BEEP CODES
Beep Codes Beep Code Description Failure Coverage 1 System Board: BIOS ROM failure System Board, covers BIOS corruption or ROM error 2 Memory No Memory / RAM detected 3 Chipset Error (North and South Bridge Chipset DMA/IMR/ Timer Error for Intel platform); Chipset Error System Board Chipset Failure Time-Of-Day Clock test failure. Gate A20 failure Super I/O chip failure Keyboard controller test failure. 4 RAM Read/Write failure Memory failure 5 RTC Power Fail. CMOS battery failure 6 Video BIOS Test Failure Video card / chip failure 7 CPU Cache Test Failure CPU failure 8 LCD LCD failure
The numbers indicate the number of Beeps. Four beeps = RAM problem. Try reseating the RAM modules and if this still does not work then remove the RAM module/s and take them to a computer repair shop and get them to test the RAM for faults.
I have just finished pulling it to bits & putting it back together all good its back up and running.. :)

When you moved your pc you probably knocked the graphics card loose. You can open it up and try re-seating it. Make sure you unplug the pc first and then press the on button for 10 seconds to clear out all the power from the power supply before opening the computer up.
Also, If you are using a KVM... Unplug the KVM's power cord for 30 seconds and plug it back in. That will reset it.
