I have lost my web browsers. I tried switching to Mozilla Firefox from Internet Explorer 7 and now I have no browser. When I reboot I get a message some files are missing and to please reinstall. Transparency is temporarily disabled because an application that uses directx or 3D hardware is currently running. I get a web site of www.nvidia.com. When I look in the task manager I see AOL and HP updates are the only things running. I’ve tried System Restore and have downloaded Internet Explorer 8 but neither worked. How can I get a web browser to work without doing a system recovery and losing all my data?
Troubleshooting Web Browser and Graphic Card Installations
Nvidia Transparency Error
There are a few different things going on here. The transparency error that you’re getting seems to be caused by an incompatibility between your Nvidia graphics card and something that you’ve downloaded. The first thing that you should do is check the Nvidia website for driver updates, which might resolve the issue. However, it is more likely that something you tried to run on your computer conflicted with the Nvidia transparency feature. However, this error message isn’t a big deal and simply clicking OK will close it. If the error returns, you can disable transparency using the Nview tab after clicking on the Nvidia icon.
Disable Windows Aero Glass Transparency
Alternatively, Windows Aero Glass transparency is an effect within the graphic user interface of Windows Vista so, if you are running this operating system, you can manually disable the application there.
- Click on any unoccupied spot on your desktop
- From the popup window options, right click on Contextual Menu, then Personalize
- Choose Windows Color and Appearance
- Uncheck the box beside Enable Transparency
- Click OK
Remove Firefox in Windows
Now let’s deal with your web browser situation. First of all, there is no reason why you can’t have both Firefox and Internet Explorer running on your system. You can use each browser as you like and they won’t interfere with each other. That said, it isn’t as clear that your installations are working so I think you should start by removing some stuff. To remove Firefox:
-
- Click the File tab at the top of the Firefox window and click Exit to exit Firefox
- Click Start, then Control Panel
- Click Add or Remove Programs (XP) or Uninstall a Program (Vista)
- Find and Select the Firefox listing and click Remove (XP) or Uninstall (Vista)
- The Firefox Uninstaller will open, click Next, then Uninstall
- Close Firefox and click Finish
Reinstall Firefox for Windows
Now, if you still want to install Firefox, begin again by downloading the application directly from the Mozilla website. When installing Firefox on a Windows based computer you have to make sure that you specify that you want the version made for Windows, since Firefox is mainly marketed towards Mac users. There is a full list of versions for different languages and operating systems here, but the site will automatically detect your platform and recommend the appropriate installation. Close all your open programs before you start.
- Click the Download Now icon to download the set up file.
- When the file is on your desktop, click it twice to launch the installation wizard
- Click Continue on the User Account Control box
- On the Welcome screen click Next
- On the Setup screen click Next
- The files will transfer and then show a box confirming that Firefox has been installed
Run a CHKDSK to Repair Internet Explorer in Vista
For the Internet Explorer Installation, if you are running Vista, run a disk check to repair the IE installation.
- Click the Start button, then type cmd in the Start Search bar
- In the Programs list, right click cmd and then click Run as Administrator
- If asked for a password, click Continue
- In the command line type sfc /scannow
Repair Internet Explorer in XP
This should resolve your Internet Explorer problem. If you are running XP, follow these instructions to repair the IE installation:
- Open Internet Explorer
- Select Tools, then Internet Options
- Click Advanced, then Reset
- In the dialog box called Reset Internet Explorer Settings, click Reset
Now, before you update your IE installation, I think that you should visit Windows Updates and look for any available updates for XP or Vista. Then you can go to the Internet Explorer website and install the latest version. I hope this helps!
