Firefox 7 causes computer to randomly reboot. WinXP on an HP xs4400 Workstation
After installing Firefox 7, my HP xw4400 workstation randomly reboots. The computer sounds like it is running at high CPU rate, but does not show high CPU or memory usage in Task Manager. Running Win XP with all latest updates. 2 GB of RAM. 2 Intel 6420 CPUs at 2.13 Ghz. This began happening with the upgrade to FF 6. FF 3xx runs just fine.
