    Hi

    I'm putting together a computer for my dad out of a few parts I no longer need and was creating a new partition on the hard drive in preparation for a format and installation of Windows.

    However, whilst the the partition was being created the power died. Now the machine won't switch on. There is a red LED on the motherboard that lights up when the power button is pressed and the processor fan twitches, but doesn't start turning. There's no power to the CD-ROM drive.

    I've tried disconnecting all disk drives, removing/switching position of RAM etc, but nothing seems to work.

    The case and power supply are new and the machine was working fine for 30/45 minutes prior to this happening.

    I'd appreciate any thoughts - I'm afraid it might be a problem with the motherboard, but am not really sure.

    Thanks in advance, Jake

    Hi again - sorry for the delay.

    I cleared the CMOS to no effect, but have since discovered the power supply was to blame. This was brand new and lasted a massive 30 minutes - beware Dabs value cases UK customers! :) (The front of the case was also cracked when it arrived!)

    Luckily a friend had a a 2nd hand spare and the PC is now working fine.
