Mouse click opens new program, window, tab etc. after "idle"

Hello.

First, sorry about my bad english. I'll try my best.

And the problem. Installed Windows 7 Ultimate 32 bit on my computer. It's working with that 30 days trial now, cos I'm testin how does it work on my HTPC. It runs fine, no crashes or BSOD. I can use it and no problems.

It is updatet with windows update, and also I have loaded and installed latest drivers for my hardware and other devices.

Ok, so Windows runs like it should be. But when I'm not doing anything whit it, it start acting weirdly. For example. I'm listenin music from netstream. It's ok. But after while I try to click running programs (like firefox) tab in taskbar, it doesen't bring allready opened firefox to screen. It opens new one. In firefox, when I click link, it wil open in new tab and that shoudent happen. Mouse lost scollin, and it turns to zoom (the middle button in Logitech Anywhere MX). In desktop, if I click any of the icons, it won't start the software, but instead it opens "Properties" window instead.

It helps, when I log out, and log in. Works some time, but after not doing anything it starts again.

Don't know what to do? Is it Windows, or is it my hardware?

Sorry, I really don't know if I used proper terminology. Ask for more details. It's easier to me to answer a question, than write from my own(?). I've tryed to google if I can find some answers, but the answers are for Internet Explorer opening new windows and that's not the pproblem, because every software does that.

Windows 7 looks good, works fine and I will buy the license for this, but it qould be very nice if someone could help me with this "little" problem.

Problem solved. SSD is broken so that's why windows is acting weirldy.
