1.1 does not compare directly with the 1.2 of the duo.
A 1.1 is so old it was never going to run HD videos.
As is now clear!
The extra memory will increase the speed of program switching as they are now resident in memory rather than paging from the harddrive.
Yes, I know how it works. It is now
much nicer running more than one application at once. Two used to be just about okay, but three or more could be a pain. Now I'm often just minimising applications rather than shutting them down completely.
To speed up boot up you'll have to do another clean install as 3-4 years is easily enough time for boot up to slow down due to various updates.
Well, that clean install would be years out of date so those updates would all get loaded up again as soon as I connected to the internet. But yes, there's probably all sorts of orphaned crap piled up in the Registry which it would be nice to clear out. To be honest though - the computer stays on all day so it only has to boot once. It doesn't really matter if that takes a couple of minutes instead of one.
Anyway, despite all of the fuss trying to speed up the tower PC, now that I've discovered how much faster the laptop is, I think I'll start using that as my main PC with the monitor, mouse and keyboard pinched from the tower system! It has more RAM (2 GB) than the tower and is quiet so I can record in the room without my mic picking up computer noise.
I think I'll partition the tower's hard drive and make it dual-bootable. Partition 1 can be a backup Windows system in case of problems with the laptop. Partition 2 can eventually be my
Play-With-Linux system but I'd need to buy another monitor, keyboard and mouse for that.
