Having problems with your PC Desktops ?

I have a pre-built system from a local dealer and recently the computer just quit working. It will not power up, have checked all the connections etc. don't know what else to do. help?


Answers :

Unhook all the cables and power connectors and make sure only the power supply is connected to the motherboard. Then turn on the computer. If it still doesn't turn on then try a known working power supply in the machine, if it still doesn't turn on then the motherboard is bad and would need to be replaced.
