So I am having a very weird issue with Windows 7 Ultimate 64-bit.. If I open Safari 4 or Internet Explorer, the taskbar crashes (if I leave the window open or minimize it, however it doesn't crash if I close it completely).. and then I hit CTRL+ALT+DELETE and the taskmanager also crashes and I have to log off then back on or restart completely. However, if I use the 64-bit version of Internet Explorer, this doesn't happen. It is ONLY happening with Internet browsers as I have checked with other applications. I have't installed anything I believe to cause this.. And I have no system restore points to restore too What shall I do? I can't reinstall, unless 100% necessary as it will take me days to get all this working like it used too.. Thanks for any possible help, Matthew.
