So lately I've been getting lag spikes every 30 seconds or so. They last no more than 1 or 2 seconds, but they are incredibly annoying.
For example, I will be typing, scrolling, clicking something, or watching something and it will completely freeze for 1 or 2 seconds, then suddenly jump to where the screen is supposed to be (like to the tab that SHOULD be showing if I clicked on a different tab during the lag spike)

Here are my specs that might matter:
Windows 7 Ultimate x64 build 7600
6GB DDR3 1600 RAM
Intel i3 540
nvidia 8800 GTS 512

Everything was fine. One day I restarted my PC (I usually set it to sleep at night, but this time I had to restart) and after that I noticed the lag spikes. The only significant thing between then and now is probably reinstalling TESIV Oblivion but I do not see that being an issue.

These lag spikes are not related to my web browser, as they happen even when I do not use the internet. However I DO NOT GET ANY LAG SPIKES WHILE I AM PLAYING A GAME. When my PC is dedicated to running a game I do not get any lag spikes at all. They only happen on the desktop / internet.

Anyone have any tips? Possible causes?

Open task manager to the Processes tab. Sort on the CPU column with highest usage at the top. Next time there is a spike, see which process is chewing the cycles.
