Hi Triggerfinger,
I don't know - I'll try that tonight and see if that's the case - but as I said I bought a brand new keyboard for it so I wouldn't have thought that was the problem. But then again in the wonderful world of computing who knows? I did try a USB keyboard in it (it doesn't seem to have a PS/2 connector) and it still beeped like crazy. Strange thing is that after I posted, I got mad with it again, and once more removed the RAM and battery. Put them back and it didn't beep. I was able to install a different antivirus and run it through to completion (it had an out of date one on it) which found nothing but a few tracking cookies. However, towards the end of the run, the desktop icons (which had been stable) began to flicker as though something was stuck again. I shut down the machine, and on turning it on again it started its usual trick - beeping like crazy! I'm currently running a memory test on it - 50 passes and it's at pass 16 at the moment - it hasn't found anything so far, but I'll keep you posted.
Thanks for replying
Dave
