Trouble Shooting Tip (Part 1)

Proper way to troubleshoot a particular problem!
Problem: No display appears on your monitor screen upon turning on your PC

Performs the following:

1. Check both power indicator of your monitor and CPU it its lit? If it's lit observe HDD LED if its actively blinking or press Numlock or Capslock keys to see if keyboard responds. If keyboard responds, it is possible that the problem lies in your monitor(try also adjusting brightness control of your monitor-applicable for older models only).If none of the above works,chances are that you have a defective monitor.
2. If you hear beeps (usually 3 beeps) just after you turn on your PC, keyboard is responding and HDD LED is active, the problem maybe cause by a defective or ailing VGA Card, try re-socketing the card and clean its contact edge by a pencil eraser. Try replacing a known good VGA card when you feel necessary.
3. Check for loose cable connections.
4. If Keyboard dont responds and monitor displays "No signal", its possible that the problem lies in the CPU unit,try removing the memory chips and clean contacts by a pencil eraser. If still nothings happen continue your isolation test in your micro processor, mainboard and power supply.You may also try removing other devices attached to you PCI slot, until the defective part is identified.

Ask,Is the power cables, keyboard and mouse connectors properly connected? Is the power rating going to the PC sufficient?Performing this simple task might save you time in fixing a particular problem.
