Hi Essexboy,
I have run the OTL and hit the cleanup button.
By the way, another query, it seems that the Available Physical Memory on my laptop can fluctuate quite greatly, it can drop from 300+MB to less than 20MB in a short period and this causes my laptop to slow down (this happens even though no program is running). And I need to restart it several times (and by force at times by pulling the plug) to get it back to running at an "acceptable pace".
Thus, is there anything I should pay special attention to so that Available Physical Memory would not be fluctuating so much, thus affecting the speed my laptop is running at because it is extremely frustrating when I need the laptop to work quickly for work purposes.
