I have a problem with my Esprimo E9900, pressing the start button at the front of the PC does nothing, no lights, no fans. If I press the small white button at the rear of the PC next to the fan, it will go through a power up sequence for about 10 seconds and then power down, if I then press the start button on the front of the PC, the computer will start and then boot into windows 7 as if nothing is wrong, I can then use the computer all day until I power down. The next morning I have to go through exactly the same procedure in order for it to work......
What is wrong with my PC, please help!!
