Yes, exactly. I had been using CCleaner previously anyway, but became suspicious that perhaps something on the software side was slowing things up anyway.
As you said, I formatted the hard drive, installed windows and loaded up software from scratch again. I was a bit disappointed that (subjectively) it seemed no different from before.
Perhaps software gets more resource hungry as it get revised as has been suggested, or perhaps it's just my memory playing tricks on me.
Apart from getting a techie to check your system, I am clueless.
The difference can be very subtle, and subjective. Over time I have found that I have become used to a fast signal. When it slows, I go on a witch-hunt, dumping all my deleted emails, and junk emails, and rat through sent emails to remove those with files I attached, just to free-up another 200MB or so on the HDD. Of course this does nothing for speed!
I then go looking for programmes I don't need, and find none! Or none that I feel comfortable tinkering with anyway. There are so many media-play-record-burn files today, I am sure I have a plethora of duplication on my machine.
Flash
Direct-X
Windows Media Centre
Windows Media Player
Windows Movie Maker
Windows Photo Gallery
Windows Defender
Then there are
Adobe Reader 9.1.3
Adobe Acrobat
Adobe Air
Adobe Flash Player 10 Active X
Adobe Flash Player 10 Plugin
Surely some of these are duplications or unnecessary programmes?
I would love to delete some of these, but don't want to start down that road - something in a former life is warning me telepathically "Don't do it!"
Then there are things like Skype, Messenger, etc which can be a drain on resources.
I have turned off Silverlight, and the Phishing filter.
I run Windows Live OneCare on three home computers, and I think this can slow speed a tad.
We use a Wireless Router - D-Link G604T, and can have 4 computers hanging off that. Naturally the speed of downloading is slowed as a function of the number of computers in use at one time.
That's about as far as my knowledge goes WS.
It's more than my father and grandfather knew, but not as much as my sons know!
How times change! And to think it used to be the role of the elders to teach the young!
I'd love to know the thoughts of others on this issue - indeed on any issues that can make computering more efficient.
EDIT - I just looked through my programmes files - there are truckloads of MS patches and updates, plus Service patch 1-2-3 for my Vista.
The sooner we have the MicroSoft Revolution the better.
I run a Mac generally - and there is none of this rubbish!
