No tower power?

April 3, 2009 at 04:10:55
Specs: Windows XP, 450/256
Pc worked fine yesterday. Turned it on today and nothing..no power..no fans, no lights. Thing is though, I can use the wireless interent from it ok ( my router is pulgged into it) ie on another machine with the one that wont show lights.fans etc powered up. Can anyone shed any light on this please? Do you think its a faulty on/off switch...can it be the power supply with the router working plugged into it? Thanks

The power supply on the PC has nothing to do with the wireless router. Once the router is setup & configured, it doesn't need to be connected to a PC to be able to broadcast it's signal.

It's unlikely the problem is with the power button on the PC, it's probably a bad power supply.

psu will have a label on it with wattage etc. depending on the type, a new one does not have to be identical . eg. if you have a standard ATX format PSU with say 250 watts on it then one with higher wattage will do, depending on where the label is stuck to psu you might need to remove psu from computer casing to see it.
Some makes of PC eg. Dell, Compaq HP etc use special shape PSUs in some of their PCs and some also have different wiring plugs in which case you can only use their special PSU in those PCs.
The PSU is the most common part to fail in a PC I reckon.
A PSU outputs various voltages. If one voltage output fails then the PC will not work, but sometimes 'bits' of the PC might show some sign of life eg. lights / fans
