i am trying to sort a mates computer out,the problem is that it will not boot up all i get is the cpu fan running, nothing on screen , this is what i have tried so far changed the power supply still the same. disconected hard drive from motherboard still the same. removed memory ,also disconected dvd drives any ideas thanks ps the computer is only 3 years old
I see that you have already changed the power supply, thats what I would have suggested next. Could the changed power supply be faulty, I know it sounds unlikely but just a suggestion. Other than that I am struggling to think what could be wrong. If there is a small local computer shop in your area it may be worth taking it in for them to have a look at, just ask them for an estimate before they actually carry out any work. Sorry I can't be anymore help.
