Stan, if you're using Windows 7, I'm wondering how much RAM your PC (whether it is a desk-top or lap-top, doesn't matter!) is using?
You can't use more than 9 Apps.....without the mouse playing up!?!
I may be still using XP Pro, BUT, I have 12 Apps.....in my System Tray.........with a cordless mouse/keyboard 'set-up', and......4 Gbs of RAM.
(With no 'mouse/keyboard problem' in sight. In fact, I can sit 30 feet away and as long as I can see the monitor-screen, my PC still works....just fine.)
My monitor is a 22-inch Wide-screen LCD, it 'doubles-up' as my TV as well. (High Defintion, at that, too. I get Melbourne, and the 'country stations', to boot.)
Luck, on my part?
Nope.
Good planning, yes. (Of what I wanted to achieve....with my PC!)
As a 'Gamer' PC, so far, it handles everything I throw at it.....with ease.
Maintenance-wise, I do it all myself. (cleaning out the dust, regularly 'reseating' that CPU with thermal paste...to ensure that the CPU never overheats due to the possibility of it being wrongly installed or of the paste getting too old.)
What do I need a 'computer techie' for....when I can do it all, myself?
I learnt a long time ago, over 12 years ago..........to save on the cost of repairs, I had better learn 'how' to fix my PC....fast.
(It's my PC, I should know it better than any 'techie' ever will have to...working on just what I may say is wrong with it.)
In all the years I have been answering 'enquiries' here, that has been the 'mainstay'...of what I've been trying to teach/encourage others...to do.
To learn how to.....fix their own PC (whether it be a desk-top or laptop).
HELP is closer 'at hand'...than you think it is, right on your PC, believe me, all you all have to do, is,........read on the 'how-to'....in Help/the Manual/ the README.txt file/Manufacturer's websites.
It's all there, IF you care to take the Time....to look.
(But, unfortunately, a lot of you won't do so....because of your ignorance/arrogance......worse still, your own stupidity!)
