Windows

1. Turn on the computer and begin hitting the 'F8' key when you see the BIOS screen. This will take you to the Safe Mode menu. Use the arrow keys to highlight “Safe Mode,” then hit 'Enter' on your keyboard. This will boot your computer in Safe Mode, a minimalist manner of operating Windows that runs only essential Windows files.
2. If using Windows XP in Safe Mode, click the 'Start' button and then click 'Run.' In the box that pops up, type “msconfig” and hit 'Enter.' If using Windows Vista or Windows 7, click the Windows logo in the bottom left corner of the screen, type “msconfig” in the search field and then hit 'Enter.' This will open the System Configuration Utility.

3. In the System Configuration Utility box, click the 'Services' tab, check the box that reads, “Hide All Microsoft Services,” click 'Disable All' and then click 'Apply.'
4. In the System Configuration Utility box, click the 'Startup' tab, click 'Disable All' and then click 'Apply.' Next, click the 'Close' box. A box will pop up that prompts you to restart your computer. Select 'Restart' and let the computer restart itself, allowing it to boot to Windows normally.
5. If the computer still stalls when trying to boot to Windows, restart the computer and boot to Safe Mode again. Run your antivirus program in Safe Mode, deleting any files that are flagged as viruses, spyware or malware. Restart the computer and boot to Windows normally.

1. Open and run the Internet Explorer Web browser application by either double-clicking on its desktop icon or by clicking the 'Start' button, 'All Programs' and clicking on 'Internet Explorer' in the menu.
2. Click on the 'Tools' option located in the top menu bar of the Explorer page.

3. Click on 'Internet Options' in the drop menu.
4. Click on the 'Advanced' tab and browse the 'Settings' list until you come to the 'Disable Script Debugging (Internet Explorer)' and 'Disable Script Debugging (Other)' options. Insert a check mark in the option boxes by these two settings to activate them.
5. Click on the 'OK' button, located at the bottom of the 'Internet Options' dialog box. This will initiate the changes and eliminate runtime error debug dialog messages.

1. Run System Restore to revert your computer to a previous configuration if Windows begins displaying a Blue Screen of Death after you install a new device driver or program. Open the Start menu, type 'System Restore' in the 'Search programs and files' field at the bottom and click the 'System Restore' icon when it appears on the results list. If the change you made to your computer prevents it from starting normally, restart the computer and tap the 'F8' key before Windows loads. Highlight 'Save Mode' and press 'Enter' to start Windows in Safe Mode, which skips loading non-essential device drivers and startup programs.
2. Check your computer for a cooling issue that causes the processor to overheat. If your computer's fan always spins at the maximum possible speed -- or never spins at all -- it is possible that the air vents are blocked or that the fan has stopped functioning. Resolving a cooling issue often requires opening the computer, so hire a professional for help if needed.

3. Check your computer for viruses. A virus infection often makes a computer behave in unpredictable ways, possibly resulting in crashes. If your computer has no anti-virus software installed, install a free program such as Microsoft Security Essentials, Avast! or AVG. Run a full scan of all files on the computer to locate and remove a virus infection.
4. Remove any hardware that you recently installed if you began to see a Blue Screen of Death after installing it. Bad memory -- though rare -- can cause this type of error message. You may also see blue screen errors if the power demands of new hardware exceed the specifications of the computer's power supply. If you installed a video card that requires an auxiliary power connection, you may also need to upgrade your computer's power supply.
5. Scan your hard drive for errors. Windows has a built-in tool for this; open the Start menu, click 'Computer,' right-click the icon for your computer's primary hard drive and select 'Properties.' Select the 'Tools' tab and then click the 'Check Now' button under the 'Error-checking' header near the top of the window. Many hard drive manufacturers also distribute tools to diagnose hard drive issues. Check the support website for the hard drive manufacturer for a 'Downloads' section to see if a tool is available for your hard drive.

1. Access 'Control Panel' from the Start menu and then choose 'Performance and Maintenance.'
2. Click 'System' and then go to the Hardware tab and click on 'Device Manager.'

3. Find the device that is registering an error by expanding the nodes of the appropriate category. If the device has a red 'X' on the icon next to its description, the hardware is disabled; proceed to Step 4 to enable it. Otherwise, go to Step 5.
4. Go to the General tab and click 'Enable Device' found under the Device Status section; then press 'OK.' (Note: You may have to follow prompts, as indicated through an enabling device wizard. If you do, continue to click 'Next' and follow the prompts until the process has completed.) Test the hardware. If an error is shown, proceed to Step 5.
5. Go to the General tab and click 'Troubleshoot' found under the Device Status section then press 'OK.' Follow the prompts to solve the issue. If an error is still shown, proceed to Step 6.
6. Go to the Driver tab and click 'Update Driver.' Follow the prompts until the process has completed and then test the hardware.

1. Create a backup of your computer's registry and system before getting started. This is to ensure that you can restore the computer if something goes wrong. If you make a mistake when editing your registry, your entire system will be corrupted.
2. Delete the process from the Windows Registry. Open your Start menu, click 'Run,' and type in 'regedit.' Press 'Enter.'

3. Double-click the HKEY_LOCAL_MACHINE folder. Inside that folder, double-click 'Software.' Open the 'Microsoft' folder, then 'Windows.'
4. In the Windows folder, open 'Currentversion' and click on the 'Run' folder. Click on 'WildTangent CDA' file (RUNDLL32.exe). Delete the file by pressing 'Delete' on your keyboard.
5. Restart your computer and make sure that everything is working normally. The error should now be gone.

1. Open the Start menu and type 'gpedit.msc' into the Search bar. Press 'Enter.'
2. Click the triangle icon next to 'Computer Configuration', then 'Administrative Templates' followed by 'Systems', then 'Internet Communication Management', then 'Internet Communication Settings' on the left pane of the window.

3. Double-click 'Turn off Windows Error Reporting' on the right pane of the window.
4. Click 'Enabled' and then click 'OK.' Windows will no longer perform error reports.

Basic Registry Correction
1. Open the Registry Editor. In Windows XP, click the Start button in the lower left of your screen, then 'Run,' and type 'Regedit.exe' and click 'OK.' In Windows Vista or 7, click the Start button, type 'Regedit' in the search box and click the 'Regedit.exe' result.
2. Navigate to 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders' in the Registry Editor. Use the file hierarchy displayed in the left pane to find the correct folder.

3. Compare the registry values displayed on your screen to the table provided by Microsoft. There are different tables for different versions of Windows. If all the data matches up, you do not need to take any action in this registry section.
4. Correct the values one by one that do not match the information from Microsoft. Delete the values by right-clicking them and selecting 'Delete.' Create a new, correct value by clicking the 'Edit' menu at the top of the window, then 'New,' then 'Expandable String Value.' Type the name provided by Microsoft for the new key that displays. Lastly, right-click the value you just created, click 'Modify' and type the text that Microsoft lists under 'Value data.' After correcting all values, close the Registry Editor and restart your computer.
5. Repeat this process exactly in the 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders' location of the Registry Editor. Use the corresponding list from Microsoft.
