Hi. ive got really low memory on my laptop (4%), ive bought some more memory but i need a screw drive to put it in and i cant get that for a while so i was wondering, is there any program i can download for the time being that will speed up my computer a little until i have time to go and get a screw drive? it doesnt have to free up loads of space just enough to last me till i can put the memory in. thanks.
