My computer is running but is not booting up. Why?

Question

I can hear the computer running but I have no monitor, keyboard, or mouse functions. Any suggestions. Thanks for your time.

Answer 1

i m sure something has died inside. like some parts of motherboard. because if your motherboard is dead then there will not be any power supply to other devices.

Answer 2

Hard disk may have died.

Do you see the initial boot screen (text) and can you enter the Setup screen - if not you may have a serious motherboard problem - bad microprocessor, bad memory, loose card, etc.

You can also reseat any plug in cards - this can sometimes solve the problem.

Answer 3

Your problem is one of the below:

Bad HDD

RAM

Main board

CPU

PSU

Video card

You PC is running-put in your Windows CD and restart and see what happends,if it boots it's your HDD.Take out a RAM if you have more than one-try it-if no try a other one-if still no.Make sure all cables inside are really in tight.

Check your PSU out put. Or maybe try to get into the safe mode-if so run a virus scan and turn his clock back to when everything was working.

Answer 4

It could be a lot of things. Many times it will be a stick of RAM that has burned out. Try removing one stick, and try each one alone.
