I have windows XP, IE7 and Opera installed. How can I do to fix my windows.

I recently had replaced by Dell (XPSM1210) cooling system. The keyboard has been replaced and a bigger HD was installed. Windows XP has been reinstalled and updates have been made except SP3 and I also downloaded IE7 and the latest version of the Opera browser. Everything worked well, but I failed my configuration of Opera and couldn't fix so I uninstalled opera and it's associated files (settings). After that I reinstalled Opera, once again everything worked fine until recently. I'm having a problem with my space bar does not not in a browser. I have to hit the space bar a couple of times to make it work most of the time (press hard). I thought it was a bad keyboard and another is sent to me, but I just noticed that my space bar works fine in Notepad and OE then maybe that's not a bad keyboard.

I have not reinstalled everything I had on my computer because I wanted to be sure that the basics working first.  I have uninstalled anything that I shouldn't when I got Opera, so I think I need to fix my windows but I've never done before (by myself). Should I uninstall IE and Opera first? Should I re-install my drivers? Should what order I reinstall everything? I hate trying to get the settings for my return to the way they were, I used the files and transfer settings Wizard, but I always had to make some changes, is there a better way to recover my settings?

I hope I posted this in the right section. Your help is greatly appreciated.

Hi justmeliveID,

Method 1

I suggest that you use the system restore and restore the computer to the point before you install Opera web browser on the computer and check if it helps.

Method 2

If the previous step fails, then check if the problem persists in the safe mode and after return with the result.
