My wife's hewlet packard desktop running xp started messing up recently. The clock was showing the wrong time.
So I guessed it needed a new battery.
With the pc turned off I changed the battery and when I started it up it was showing a counter in the top left corner which
I have found out is checking the ram.
When that finished I had to enter a new date and time and click F1 to save the new settings. all ok so far.
But now for some reason there is no sound, either from the back (which is where the plug has always been) or from
the headphone socket on the front???
I really need some help here. So if anyone has any ideas, please let me know.
ps. The clock is working fine now.
