I don't know what kind of desktop it is....it was given to me by a friend.

Problem: I turned on my PC but neither the keyboard, mouse or monitor is turning on. The monitor says "In Power Safe Mode press any key on keyboard or move mouse". I made sure that the keyboard and mouse is connected and moved the mouse connection to different usb but the little red light does not turn on. I plugged the mouse into my laptop and the mouse red light comes on. Even the light for the keyboard does not go on. Please help.

Do you heard any Beep! when you turn it on? If no, then the computer don't even finishes it's power on self test (POST). Check that the computer is properly plugged to a power outlet. Check the power supply and it's connection to the motherboard.

That computer may not support USB keyboard and mouse on the BIOS level. Try with a PS2 keyboard and mouse. Those have a small round connector with several connectors surrounded by a metallic cylinder.

It's possible that there is no operating system installed. Once an operating system is installed, the USB ports should be recognised.

It's also possible that the USB ports are defective. If that's the case, it's also probable that the whole motherboard is on the verge of failing.
