Dear Managers,
I'm getting sick of those Hardware errors. We have had those a several
times already. Digital replaced almost every hardware component from this
alpha 3000-300X machine.
They informed us that we had problems because we were using the J300
multimedia card. Apparently there is a problem when you use both sound
and video on this card in combination with the processor which we have.
The fact is that the machine crashed again, while noone was using the
card at this time.
So I would like to know if someone else has has had a similar problem and I
also want to know if someone could give me more info on what exactly the
problem is. That is, which part of the hardware fails. I include an
extract from the uerf.
Thanks,
Have a merry christmas and a happy new year all with less crashes as I
have :)
