I haven't contributed to this before as my Windows knowledge is  
minimal but I have had the same symptoms over the same period, low  
mips, etc. and now back to normal.

VRPC Adjust on hard disc Drive E.

Looked at several of the T.O.M.S. Suggestions without doing anything,  
after which it went back to normal. Also checked the effect of other  
programs starting before or after VRPC but that seemed to make no  
difference.

Most odd.
