  1. Any help appreciated

    I have made no changes to the PC but it will not get to windows load up.

    POST tone sounds like 1 long then silence though possibly 2 short to follow which would suggest a graphics card problem.

    I have changed the graphics card for a working one in another pc and it also does not work in this pc.
    I have tried my card in the other pc and it works fine
    I have used another pci-e slot with the same results
    I have tested the monitor with another pc and it is fine
    I have removed all peripherals
    I have removed RAM stick by stick and also in pairs
    I have checked all internal wiring

    I am a bit stuck now and suspect a motherboard problem

    Help appreciated

    What BIOS does your motherboard use?
