Unhappy All Desktop Icons Select, Caps Lock Randomly Turns On and Off

Hello everyone,

I am under the gun and have a problem that is causing me to tear my hair out! On a clients Toshiba Satellite Laptop, when I try to select a single icon on the desktop, all icons up to and including that one, from either the top of the screen or the bottom, are automatically selected, after which the original icon that I attempted to select can not be unselected without a reboot! No matter what I try, multiple Icons select. If I click away from the icons, the original icon becomes the only one selected, yet I can never double click it without again multiple icons becoming selected. Neither Sticky keys nor Filter keys are selected, and Active Desktop is not activated.
Also, the Caps Lock key randomly turns itself on when attempting to type. I turn it off, but after a letter or two into typing, Caps Lock turns itself back on! I have popped out the Caps Lock, Ctrl, and Shift keys, and they are clean as a whistle. The keyboard is very well kept, and I see no signs of spillage.

Please Help, I am stumped, and I do not want to lose this very good customer!

Also, I have run Malwarebytes, AVG, and Avast, full scans. I also ran Advanced System Care. Initially 2 backdoor viruses were found, but they were removed and have not shown back up through subsequent scans.

Try removing the keyboard and starting the system up with a usb keyboard. Could be that a key is "sticking" even if it's not gummed up or anything.

I hate to state the obvious, but have you tried an auxiliary keyboard and mouse? It would be interesting to see if this problem remained when you were not using the built-in keyboard and touchpad. Also, a great way to narrow down whether or not it is software or hardware is to boot into a Live linux distro or even the ultimate boot cd for windows.

EDIT: Arg! too slow!

Actually, I have not tried an auxiliary keyboard (I did try a usb mouse). I am kicking myself for that now that you guys mention it--frustration is the enemy of a technician!

I will try all of these things, thanks for the prompt responses guys!

Its amazing what happens when the control buttons get stuck.

For example the ALT key.
Try opening something on the desktop with it pressed.
That one stumped me once for some time
