When I switched on one of my computers I found nothing would start except my monitor. The keyboard light, computer light and DVD light do not show as on. Have checked mains supply and mains (plug) fuse both ok. Does my tower computer power supply box contain it's own fuse. Any idea or thoughts as to what the problem could be or should I look no further and take my system to a computer hospital.
dont open the power supply it contains a capacitor that can kill you even when its not plugged in. the problem could be all sorts of things, is there any history to this problem or was it a case of one day working the next day not?
If you've checked the plug / fuse /lead firmly in then why not swap the power supply from your other computer to see if that works....you can swap either power supply either way, then you will find out if one of the power supplies is dead. If it is buy a new one (they are not expensive) but DO NOT OPEN THE DEAD ONE TO TRY AND REPAIR IT.
