A member of my family was changing some network adapter settings (not sure why) and they claim that after doing so the PC crashed and now it will not boot up to the bios screen or anything, no signal to keyboard mouse etc etc

Ive never heard of this happening before so Im not sure if they're telling the whole truth but either way where could the problems lie? In the psu, motherboard or network card? Maybe even the HDD?

Sounds like they were overclocking the CPU to me... And set something to a point where the system cannot boot with that setting.


    ■Unplug the power supply from the wall.
    ■Press the power button on the case a few times over 30 seconds to drain any stored power from the system.
    ■There is a round, chrome battery on the motherboard. Remove that. Wait a few minutes.
    ■With the battery still out, plug the power supply back in, and see if it will then boot, at least far enough to get into the BIOS. It might actually boot to the desktop at that point if you let it.

To be honest I don't think he even knows what over clocking is or even where to start with it so I dont think that is the issue

Okay, ill try this later on today, if it does work after removing the battery what should I do then? Replace the battery with a new one?

If this doesnt work however do you have any other methods?

I don't think the battery is the problem. It should be fine, and after you see what happens with what I listed above, next time the computer is off, unplug it from the wall again, press the power button like before, and put the battery back in.

They battery simply provides a tiny bit of power to keep the BIOS settings in memory when the computer is off. They normally last about 5 years.
