Thanks guys.
I have tried all the obvious things, including defrag etc. theres bags of space left on the hard drive and no HDD hard working. Rather a 'click, click, click' sort of usage...
It's now locking up for an extended time and then displays the following message once it decides t wake up again:
"Logon process has failed to create the security options dialog
Failure - security options"
It's operating MS Vista with Norton AV but I'm not sure what it refers to - it gives no clues..
Any further suggestions before it's driven over by an HGV....?
