I have just installed an internal modem for my neighbour.
I connected to ISP and all works well.
However, this morning, I found that the PC would not boot up. The power supply reaches the power unit OK, I can see and hear the cooling fan. It seems that the Hard Drive is not responding. There is no activity when I try to boot up from any kind of disc. The monitor screen remains blank. (monitor works OK) Could this be Hard Drive failure?
As a matter of interest, before closing the case yesterday, I pressed the motherboard battery to make sure that it was secure, it gave a slight click, I then secured the PC casing, I put the PC away, until this morning.
