Problem with Windows7?: touch pad, point mouse stuck...

Hi,

I have installed WIndows7 in my Laptop dell xps 1330 about one and half months ago. It was running perfect and was not a trial version for one month.

However, still I can update my windows and so forth as original. The fact was, I installed some programmes and softwares which I used before, in Windows Vista! Now-a-days, I experience having problem with the touch pad, CD Rom hardware and Volume...

1. touch pad stucks, pointer doesn't move sometimes.
2. CD Rom start functioning automatically without having a CD inside.. sounds like CD is ejecting from rom.
3. volume button starts increasing automatically and sometimes mutes !

what I guess, it's a virus. I installed a scroll pad driver, I thought the problem was due to the driver. After uninstalling that driver, the touch pad was functioning normally (without the scroll functioning though) and the error was removed. But after two days, I see the same problem again..

Please help!

Thanks in advance.

Do you have a run down battery?

I had the same problem, until I took out the battery and ran on just the power cable. Try it. It should definitely work. It worked for my friend's laptop as well.

Good luck!
