Re: Which is better?
I'm sorry for the long time to respond. I have windows xp with a 160 gb hdd. I deleted a few things and freed up about 25 gigs and have a bit more to go, but the computer is still really slow. I haven't deleted any programs had a few movies on here that were like 4 gigs each.
Edit: I have more free space now then i do used.
Start by opening the TaskManager (Control-Alt-Delete)...Taskmanager))
Have a look at the number of processes are loaded into memory. The more of those processes that are running, the less RAM memory is available to run a program in memory.
Some of those processes are loaded by the OS and can't be stopped without crashing the machine.
If you install some utilities or programs, they want to add themselves into your process list and consume more RAM memory. One that comes to mind is Quicktime. It loads itself into RAM memory when Windows boots and just sits there, taking up RAM memory space. They will claim, it's faster to 'call up' Quicktime IF NEEDED, since it's already loaded in memory. If you don't use Quicktime everyday, it's a waste of valuable RAM resources. This TSR , Terminate and Stay Resident, action, eats up RAM which could be used for other programs. Now lets add a few more TSR's and you'll see that all of them together siting in RAM are a waste of resources. Now, this does not mean the programs like Quicktime won't run, they will, just fine. Quicktime will just be loaded into RAM, from the HD, when YOU want it too, when it's needed as usual.
This is what I see a lot of. So many programs (processes), unused, eating RAM.
Now here's where it gets interesting....Windows will start using your spare HD space to swap data back of forth in what it calls Virtual Memory because RAM is so short. This writing and reading (swap file) takes time. It's certainly no where near as fast as RAM memory is, so you start seeing a slow down in performance.
So, how do you fix this? Here are some tips.
Start by going through you list of processes and take note of the ones that were installed , but not needed when you start Windows. In the case of Quicktime, launch Quicktime, goto settings and find the section where it asks if you want it to load when Windows Starts, uncheck that option. Do the same for the programs you see that have a loaded process but aren't used on a regular basis. TIP: The icons in the lower RIGHT hand corner are loaded into memory. When you tell Quicktime to NOT start with Windows, it's lower right hand icon will be gone , after you reboot and the memory it was using will be freed up.
Re-installing your OS is just starting over from scratch, of course it's going to be faster, there's less junk eating you resources. It's not always the best or only solution.
TIP: Google the name of an entry from your process list. You see that some of them are Windows OS processes and some are not.
Dump the junk Temp files, Recycle bin, Internet Web caches etc.
Defrag your HD
Run Crap Cleaner (Google it) to clean out your Registry and junk files.
Watch the processes list ect.
