    impressive..

    had a dell this morning, continual beep, no video.

    Opened it up, rebooted.."no NIC". Rebooted, no video. Rebooted, no BIOS..hmmm

    On closer inspection, the Northbridge chip has heat marks on it, and a hole right through it! God knows what happened there...I can only guess a spike or similar set it on the slippery slope towards self-destruct.

    Needless to say, that's one Optiplex GX60 that's gone in the skip (after removing everything useful from it)

    Exclamation

    Check the capacitors around the CPU.
    DELL and Optiplexes are world renowned for capacitor issues from some time back. It was a different model, but worth a check.
    The issue caused overheating and all manner of random problems with the motherboard.
    They used to do mobo swap outs, but it's probably so old now they wont support it.
    If you have many more of that model, i'd suggest checking them all in a hurry. When they go, they go at once. We had around 150 GX280s die on us previously.

    This sounds worrying if it is a known issue [although I must admit I have never heard of it!] Worrying because the majority of our stations are Optiplexes 620 or later. The breakdown:

    Viglen Incepta II
    Dell Optiplex 520
    Dell Optiplex 620
    Dell Optiplex 745
    Dell Optiplex 755
    Dell [Something] 170

    Any similar known [currently unknown to me] issues I might need to be aware of?

    You're probably safe it was only a small batch of a few hundred billion capacitors that were overfilled. It only affected a small part of the manufacturing output, but it's always worth checking, because you can never tell, when they might cut corners and use some old stock.

    Just check the capacitors on the board, they tended to swell up visibly and also you could occasionally see some kind of furry discharge.

    p.s. yes a picture would be great...

    I didn't think it was that they were overfilled I thought it was industrial espionage? Someone stole the recipe for the electrolyte but it was made wrongly which is what caused the capacitor failures?

    How to Fix Your Motherboard for $15 : When a Motherboard Fails - Review Tom's Hardware

    Think I saw a similiar website to this some time ago - that was an actual company where you could send your motherboard to and they would do the above for you.
