Two Weeks Busy Repairing PC

This is about fourth day im in task for reparing PC for societies i work under..For the second task i need to repair 5 PC and 4 printer. Still work on that :D

The most difficult part is those PC is bit old and not even similar with my own.The problem is due to compatibility and support. CD drive is not working need to use mine. Im plug out my hardisk drive about 30 times coz change hardisk. Most PC come with BIOS password. That another problem. It suck and boring like hell. This task remind me when i was Form 5
