To Humbug, I didnt get to defraging last night as I had the other problem (see my other post), I waited ages, I have lots of patience and never click click click, I just let it run but it didnt sort itself out so I CTRL/DELETE and closed my Canon program down like that. By then I had had enough. Hence when trying tonight I came up with 'the other problem'. Please see my other post I urgently need to sort this out, before hes home of Friday.
So....I didnt defrag, will do after. I will also try what you suggested when the computer runs slow, at the mo its fine again. I checked out the Indexing Service thing you suggested and this is already set to manual.
To Boxcleva, what is screengrab???
And to Bacho, how do I find out what is starting up, are they mostly the items on my desktop, I have heard this one before but am not sure to locate what is starting up when I switch on.
But please also 'my other post'.
