NOt been about for a couple of days as I have had some computer problems and really hoping someone may know what the hell is going on!!

A few months ago I had problems switching the computer on.
When pressing the switch ont he tower, the orange LED light would come on instead of the green one and the computer would not boot. I would sit here switching the computer on and off at the switch until eventually the geen LED light would come on and the computer would boot up and work as normal.

Following several suggestions, I have replaced the Motherboard, Replaced the Power supply (psu?), cables and yesterday as we were still having problems bought a new CPU unit and transferred everything into it from the old one as someone suggested it could be the on off switch that was causing the problems.

After several hours of Nigel swearing at the computer because the wires that you connect to the board are tiny, we finally get the computer set up.

I switch it on with bated breath.

Nothing.

We get the orange light, computer doesn't boot up, no green LED light and no ping that I usually hear when the computer is booting.

So I am back to keep pressing the switch on and off until I get the ping and green light.

Any suggestions?
