I am on Service Pack 2. My CPU is running at 100% with either svchost.exe or services.exe. I know that this was common in XP, server 2000, etc. But now I only seem to find posts for Vista. What is the reason?

What about SQL Server maintenance and backup plans? Maybe some are executing at night, and they have strong chances to fill all the resources available.
Windows defragmentation is another process which can take a large amount of CPU power. See defrag logs to figure out the last date it was running.
Here is Wikipedia's handy chart of the pursuit of nines:
Interestingly, only 3 of the top 20 websites were able to achieve the mythical 5 nines or 99.999% uptime in 2007. They were Yahoo, AOL, and Comcast. In the first 4 months of 2008, some of the most popular social networks, didn't even come close to that.
From the chart, it should be evident how ridiculous the pursuit of 100% uptime is...
