Hi guys, I haven't done anything on the machine since last post, because I have another little problem - the screen is cracked (I got it like that, in fact it's the reason I got it...), so I don't use it often (sleeps in a bag beneath my desk).
As to H.Ammar's suggestion, I don't have anything in Device Manager or Programs and Features with the name Arcsoft. So I don't know what to remove.
I may be re-installing with Win7 Ult x64 anyway, coz I want to add buckets full of RAM.
Will see how it goes then...
Thanx for all the input!
