G'day ,

I have recently switched on my computer and there is a intermiting bleeping noise that will not stop comping from the tower. There is also no signal going through to the monitor, and will not boot up.
I have tried taking out the wireless modem and checked all connections but don't know where to go from here.

Any replys are greatly appreciated

well definitely a hardware failure but when you turn it on is it just black on the screen? or does it at least show something? ever heard of Hiren's Boot CD?

Hi

Try to stip the PC back to a basic system as follows.
  • Remove all external devices such as printers, scanners and USB drives etc so that you only have a mouse, keyboard and monitor connected.
  • remove as many cards from the PC as possible e.g. sound card (if it is seperate from the motherboard), dial-up modem etc
  • Disconnect the power to non essential drives e.g. CD or DVD drives.
    Try booting the system. If it boots ok then gradually reconnect everything until your boot fails again to find out what was causing the problem. If it still fails then it could be down to the RAM
  • If you have more than one stick of RAM, remove a stick then try booting again. If you still have the same problem, replace the stick of RAM you removed and then remove another stick and try booting again. Do this for each stick of RAM you have until you have eliminated all the sticks.
  • If the above steps do not solve the problem then you could be lookung at a faulty CPU or motherboard.
Note that when you are disconnecting components from the motherboard, the computer must be switched off and disconnected from the mains. RAM can easily be damaged by incorrect handling. Make sure you touch the metal chasis of the PC to ground yourself before removing/replacing the RAM
