You should be able to uninstall any program from Programs and Features:
Programs and Features - Uninstall or Change a Program
If you can't figure out which program is using that driver, go to C:\Windows\System32\Drivers, and delete pfc.sys.
There is a pfc.sys driver in the Windows\SysWOW64\drivers. That seems to be the one referred to in the error messages. Should I delete that, or am I on quicksand? Here's a perfmon file I tried to upload earlier today, but didn't seem to succeed.
p.s. I have already uninstalled some of the programs I don't use. The Event Viewer still reports a lot of problems every restart though. Let me know if a new file will help.
HMMM! I just checked and no event problems at last restart.

I think I will do a clean instal of Windows and see if I can avoid all these errors. Thanks to those who have helped so far.
Well, am not having a lot of success. After a clean instal of W7, I am getting BSODs with only the MB software added to the original W7-64 installation. Can anyone help me to fix at this early stage?
Try running some hardware tests:
Run each of the three Prime95 tests:
Hardware - Stress Test With Prime95
Also run Memtest86: RAM - Test with Memtest86+
From line 10 of 10 in your event viewer.
