Hi, I selected the parts for my dads PC a year ago and someone else put all the parts together to make his PC. It has been fine but just a few days ago there have been problems with the power button at the front of the pc case.

The computer could be off and I go to press the power button it and would power up but sometimes pressing the power button doesnt do anything. Today I had to click the power button 12 times before the computer would power up.

Does anyone know whats going on? I can list the specs for my dads PC if you ask.

Thanks
 
Swap the cables that go to the mother board for the reset button and power button. They are both momentary contact switches, they may look different but they are identical in operation. Once you do that try turning the PC on by depressing the reset switch. If it works now then it is the power switch on the case that is bad.
 
use a screwdriver to start it :p. jk lol just check the wiring from the case to the mobo if that dont work then get new wires or something

Hi, I am not sure what a momentary contact switch is. I google image searched it and didnt see anything I recognized. I am not very confident around hardware, is their another way?
 
Get a flat screw driver, remove the stock switch, put the tip of the screw driver on the power pins, touch the pins for a second, if the machine boots up right away it is a bad switch, if it does not it may be bad hardware, what you're describing can be a bad switch or a common symptom of bad capacitors on the mainboard or in the power supply.
 
Hi, I am not very confident around hardware and I am not sure what the switches look like but let me tell you what happened today and maybe you can identify the problem better.

I pressed the power button and nothing happened, I then pressed the button 5 more times and nothing happened but I then tilted the tower to the side slightly and power came on. The computer didnt beep and the monitor didnt come on. I turned off power and then turned power back on and still no beep and no monitor signal. I turned off and on the power a 3rd time and the computer beeped and monitor came on.

Does someone know whats going on ?
