I have this problem on my workstation. The computer would effectively freeze for 2-5 seconds for no apparent reason, then continue as normal. While frozen the mouse would still be movable, but only on one of screens in my multi-screen setup. What can be the likely cause.

System:

CPU: i7-920
Memory: 12G of Patriot DDR3, 6 modules
OS: SLED 11, Suse Linux Enterprise Desktop, using Gnome
Main board: Asus P6T
Video: two Nvidia 9500GT connected to three displays

I am using memory at recommended settings of 8-8-8-1333. It has an XMP profile. Th CPU is a bit overclocked to 3.3 GHz, but my cooling more than allows for it. I ran the computer with all overclocks off and lower memory speed but the issue was still there.

Any ideas? Where should I start looking?
