I found a fix for this problem on my computer!!!!!
I noted several problems.
1 -- I could not open internet explorer 32 bit while I could open 64 bit ie.
2 mozilla firefox would flash the page, then crash with a crash message
3 mozilla thunderbird email would crash
I was able to restore thunderbird by going back to an earlier version
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.24) Gecko/20111103 Thunderbird/3.1.16
But the ie 32 still wouldn't open. and mozilla firefox still crashed
I tried the items posted here such as resetting, scanning for viruse etc. nothing worked.
I uninstalled mozilla firefox and reinstalled same problem. On the mozilla webpage
it suggested starting firefox in safe mode, and unchecking a hardware accelerator button. When I did that, Firefox would start in standard mode. I updated my graphic card drivers (NVIDIA GeForce GTX 460) in the windows device manager and asked it to let windows find the update. When I did that, I went back and rechecked the button in firefox to use graphic accelerator if available and it still worked.
I then did nothing else, but clicked on ie 32 bit, and it worked again. I had recently updated to ie verstion 9 9.0.8112.16421 update version 9.0.3

this is the text version on the instructions I found on the mozilla page:
Start Firefox in Safe Mode
When you start in Firefox's Safe Mode, all extensions are temporarily disabled, hardware acceleration is turned off and the default theme is used. This will help determine whether one of these is causing your problem.
At the top of the Firefox window, click the Firefox button, go over to the Help menu and select Restart with Add-ons Disabled.... Firefox will start up with the Firefox Safe Mode dialog.
For Windows XP, click the Help menu and select Restart with Add-ons Disabled....
Note: You can also start Firefox in Safe Mode by holding down the shift key while starting Firefox.
When the Firefox Safe Mode window appears, press the button Continue in Safe Mode.
After Firefox starts in Safe Mode, test for your problem.
The problem still occurs in Safe Mode
If your problem persists in Safe Mode, it is not being caused by an extension, theme or hardware acceleration. Other possible causes could be plugins or changes made to Firefox preference settings, which are not disabled in Safe Mode.
For additional troubleshooting suggestions, see Basic Troubleshooting, Troubleshooting plugins, and Resetting preferences.
The problem does not occur in Safe Mode
If your problem did not occur in Safe Mode, it is most likely because of an extension, theme or hardware acceleration. Continue following the steps in this article to determine the cause of your problem.
Turn off hardware acceleration
With some graphics card and graphics driver setups, Firefox may crash or have trouble showing text or objects on pages when using hardware acceleration. You can try turning off hardware acceleration to see if it fixes the problem.
At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP) and then click Options.
Select the Advanced panel and the General tab.
Uncheck Use hardware acceleration when available.
At the top of the Firefox window, click on the Firefox button (File menu in Windows XP) and then click Exit.
Start Firefox the way you normally do.
If the problem is no longer happening, then hardware acceleration was likely the cause. You can try updating your graphics drivers to see if that fixes it or simply run without hardware acceleration. Otherwise, your problem is likely related to extensions or themes. Continue with the steps in this article to see if they help.
Switch to the default theme
