If it's a hardware problem wouldn't McAfee first aid find it. When I run First Aid it shows two non crtical issues. My modem is apparently on COM 3 and I don't have a joystick. Both of which I can live with.
Power saving options are all swiched off.
My McAfee virus scan is v5.16 but seems to run ok on ME and the problem occurred before it was installed.
Should I have bought another Mac?
