Hi everybody

My XPS 8100 beeps 3 times on boot and don't go any further.

I have to force shutdown and retry several times to get it starting, or to "shake" something inside : memory, graphic card, CPU fan plug.  Sometimes unconnecting and reconnecting mains plug is a solution too ...

Once started, this machine works perfectly well but booting is always a problem.

I haven't found a list of the beep codes for this model.  What do those 3 beeps mean ? (slow beeps)

 

Thanks for helping
