I think you have some MAlware on it.


go to Malwarebytes.com and download the FREE edition. This thing ROCKS! I have it on mine, and it yanked off three things that Nortons, AVG, and others passed on by. Its fast, and Free! I bet after you yank off the little critter, yours will behave better.

I think I got mine from Facebook, and now run it everyday or two. it takes less than a min once set up to do a fast scan.

good luck.

Twinkles, do you have a wireless mouse or one that plugs in? My wireless mouse does that when the batteries need recharging. Also had a mouse once that had a trackball that needed cleaning often. When it was gunky under the ball, it would cause the pointer to be shaky like and miss what I was clicking on.

Thanks for your suggestions!

I'm away from home right now, so can't try them for a couple of days.

My mouse has a tail and no trackball, but good thought anyway 2K2C.

I hadn't thought of MalWare, so will try that when I return, Deji.

I might even try to install Windows 7 using your helps, JoMar.

Do you have XP or Vista now?
I found some more info about installing it on same computer vs a new or different machine.

If XP you'll have to use a flash drive or CD/DVD to back up any files or settings that you want to save. it tells how to do that on the link.

plenty of pages to explore with clickable links to more info..

[Upgrade from Windows XP to Windows 7

The Upgrade option is not available in Windows 7 Setup when installing Windows 7 on a computer running Windows XP. However, you can use Windows Easy Transfer to migrate files and settings from Windows XP to Windows 7 on the same computer. To do this, you must first copy files to a removable media, such as an external hard drive or UFD, or to a network share. Next, you will install Windows 7 and then migrate your files back from the removable media onto your computer. When you are finished, you must install your software programs again, but your files and settings will have been copied from Windows XP.]

JoMar, I've got Vista and am excited to try the new Version 7.

I'll tackle that tomorrow -- just got home and too late tonight. Thanks so much.

One other dreaded thought is that the hard drive might be failing.
Mine went like that in the early stages.
Ended up having both replaced under warranty, 20 months old.
