Power Supply 12V problems???

My computer has been acting strange lately with the CPU stuck at 100% due to svchost.exe (usually). A google search found some other people with similar issues, and they blamed a bad power supply for supplying 4.7V instead of 5V. Mine checks out at 5.1V, but the 12V supply is only running at 11.7V. I see that the only place the 12V leads go is to the mother board. Is my CPU getting temperamental due to low voltage? Do you think these are related? Do I need a new power supply?

Interestingly, the system has gotten a bit more stable since Microsoft sent out the last patch for XP a few days ago...related?

Thanks in advance for any insite.
