Computer slow under Windows 7
I've just had Windows 7 installed on my computer by my pet guru- new 600Mb C drive, along with the three existing ones, being 2x400Mb and a 200Mb (my original C drive). Intel Core2 processor. Also existing 2 Gb RAM.
I'm getting used to Win 7. However, the computer now seems to hang slightly when I'm opening a new programme, or even when I'm opening one of the drives in Windows Explorer. It seems almost to be lacking in memory, although only just over 1Gb is being used. Otherwise, no problem with reaction time, once I'm into programmes.
Any thoughts on why it's slow now, compared with before?
