Yesterday my PC died and will no longer turn on, pressing the power button does absolutely nothing. Here's how it happened:
I noticed some strange sounds comming from the PC - the psu fan was making a bit of a grinding noise, but the motherboard itself seemed to be "whining". Moments later there was a click sound and the whole thing immediately shut down and will not start up again.
I'm not completely sure if the problem is the power supply, the motherboard or both. One thing to note though is that the light on my card reader still comes on when the pc is plugged in, so it does seem that some power is going through.
