I have run the Windows XP repair and I have reset the BIOS to default settings. I have used different slots but all to no avail.
Dell support are now saying that I have to strip out the OS and start again: when the computer works perfectly in every other respect this is something I am loathe to do.
Some time ago I had a Serflog virus attack: a new one that was not known even to Symantec who eventually sent me a fix which I have run a couple of times and this reports no virus detected. Could it be that the OS registry files are corrupted preventing modems from being detected? I have also run Adaware and Spybot.
I have run Pconpoint trial version and it has found hundreds of problems with the registry and shared files: should I buy the full version and hope that it fixes my problem?
Grateful for any advice.
