Does your monitor light up, if so, swap the lead into the tower and if it still won't turn on then you know it's not the lead.
It could be the power supply, you could try swapping for a known working unit to check.
If still won't start, then unplug everything from the motherboard (except the power supply) and turn on. It should start making lots of beeping noises. If it does, replace each plug in turn till it doesn't then you know what to replace. If it doesn't, it's probably the motherboard that's faulty.

Computer not power on


Computer is not working. may be you should check all the cable is working or not ,one by one, and then check the Power Cord again.
All the power to the computer is fine. then it 's not the power supply's fault. So you must check the internal hardware such as: harddisk, motherboard, processor, memory etc.

Gateway desktop


check at any other power socket or plug any other working equipment on the same wall socket to check if the power is ok in the wall socket
if all ok then either your power cord to the computer is not properly plugged in the computer or the computer power supply may not be working.
you may then require technical assistance of computer mechanic.

No power to computer. Outlet is good. Power cord is good.


Try to do a power drain first by unplugging the piwer cable and then press and hold the power button for ten secs.after that plug the power button again then try to restart the machine.check for any indicators that the computer is getting power like sound coming offf the computer or if the cd/dvd drive is opening, check any lights on the tower or if the fan is running if not then you might need to have the computer checked.Power supply or the motherboard needs to be replaced.If the system is still under warranty then you can call your manufacturer for support.hope this helps...

My asus a7n8x motherboard based computer won't switch on - I press the power up button - and... nothing!


First try switching the power cable that goes from the power supply to the wall switch. You would be surprised at how many times that is the case. If you know for sure that power supply cable is good, You possibly have a bad power supply. You can purchase these for about $40.00 at most of your computer stores. But before spending your money on the power supply, make sure that the switch that turns on the computer is not bad. a- check power supply cable b-check computer on/off switch c-check power supply. Good Luck
