I asked her to check if everything was plugged into the back of the PC ok and into the power board...etc... and it was all ok.... I asked her to turn the power off at the wall and wait about 10 mins before turning it back on and trying again. Finally she phoned me and said it had come on after about 4 attempts.
Now (today) she phoned me and said that she is having the same problem as yesterday!! (PC won't turn on)
Does anyone know what this problem could be?
I may have to call comeone like Geeks on wheels or Need a nerd - or take it somewhere to be looked at... but if anyone has an idea of what the problem could be it would be very much appreciated!
