Is there an IE7 repair tool? The IE7 on this computer is acting quirky, such as, the monitor goes haywire when I open IE7.

I am (still) compiling a list of possible solutions to Internet Explorer 7 problems. Some of them may not be relevant to your problem and some you may have already attempted. Read through the list and try any that sound applicable. In no particular sequence, they are: 1. Red X in Internet Explorer, have a look here http://support.microsoft.com/?kbid=... 2. Start your troubleshooting for this message ‘Internet Explorer stops responding, stops working, or restarts’ at this website http://support.microsoft.com/gp/pc_... 3. If you receive the message ‘Internet Explorer cannot display the webpage’, this sometimes helps. Go to Control Panel > Classic View > Internet Options > Advanced Tab > scroll down to the Security section and uncheck ‘Check for server certificate revocation‘. Restart IE, if it doesn’t solve the problem, try unchecking these two; ‘Check for publisher's certificate revocation’ and ‘Enable Integrated Windows Authentication‘. It’s unlikely but make a note of the original settings just in case things get worse. Look here http://support.microsoft.com/kb/926431 4. If you receive the message ‘Internet Explorer has stopped working. Windows will close the program and notify you if a solution is available.’, it could be the result of an overzealous security setting. Go to Control Panel > Classic View > Internet Options > Advanced Tab scroll down to the Security section for ‘Enable memory protection to help mitigate online attacks’. If it is ticked, remove the tick from it. Also, look at Internet Options > Security Tab and uncheck the box that says ‘Enable Protected Mode‘. 5. Reset Internet Explorer 7 settings, i.e. Internet Options > Advanced Tab and click 'Reset' at the bottom and/or read this http://support.microsoft.com/kb/923737 This link explains what is reset and what is deleted, e.g. history, typed URLs. How to re-enable Add-ons is a further link at the bottom of the page http://windowshelp.microsoft.com/Wi... 6. If some links don’t open there are some things to try: - Make sure Internet Explorer is the default browser by going to Control Panel > Classic View > Internet Options > Programs Tab and click ‘Make default’ if it isn’t already. - A temporary workaround is to try running IE7 as an administrator, i.e. right-click the IE icon and chose ‘Run as administrator‘. 7. Run the System File Checker (SFC) from an elevated Command Prompt, i.e. click the Windows Orb (Start) > All Programs > Accessories and right-click Command Prompt, then ‘Run as Administrator’. Type sfc /scannow (note the space) and press Enter. This may take some time and, depending upon your installation of Vista, you may have to put the Vista DVD in the drive. 8. Click the Windows Orb (Start) > All Programs > Accessories > System Tools > Internet Explorer (No Add-ons). Now try visiting the website.

My problem with IE7 occurs only when I open the browser and go on line. After a few minutes on-line the monitor will go haywire, that is, lose all video and show a lot of jagged lines. It only happens when IE7 is running. After a re-boot all will be normal until I go back on line again. Is it possible that there is something in/about IE7 that is causing this? Would an SFC/Scannow fix it?
