I have been letting a MS techie try everything to stop my laptop from choking on 100% cpu usage and a gradually rising memory, slowing the computer to a standstill. Even with no internet access, the cpu usage swings wildly and eventually ends up at max, stopping the computer. Complete malware scans, disc clean up, registry cleanup, complete uninstall/reinstall of addons, Firefox (incl registry keys), disc defrag, almost nothing left to throw out and then reinstall. A reboot does not always help,. several times, it rebooted at 100% cpu usage. But the sysinternals performance monitor shows the largest drain on cpu is Firefox. MS has taken large files twice now to analyze the problem, will report back in a week. IE runs better but I want to continue using FX. If I can.

Did you check which programs and services are started?
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
If it works in Windows Safe mode then you have a problem with other software, likely security software or a system driver, that is running on your computer.
Make sure that you have the latest updates of your security software and major hardware drivers.
You can use the MSConfig program or the Autoruns utility to see which software and services are getting started.
