A few days ago I turned my Computer on, and it just started hanging on the Gateway Logo(Press F2 F10). It also would not allow me to use my keyboard or mouse. Then the front LED stopped coming on, and only the fan and hard drive and disc drive would turn on. The Hard drive is fine (tested), I have tried removing and reinstalling the RAM,and also the PCI cards. I’ve also taken out the CMOS battery. When I pull out all of the memory I do get the beeping. Could it be the PSU? One time last night it did go past the Gateway screen, and the mouse powered on, but not the keyboard, so I had to shut it down again. I’m not sure what else to try, any ideas?
