Locked again after a total of 11 hours 30 minutes. I will have to disassemble the PC just to check it out.

Complete freeze that I have to force reboot. I upgraded to Ubuntu 12.10 Beta2 since the problem was mentioned to be solved in Kernel 3.4 as seen here: https://bugzilla.kernel.org/show_bug.cgi?id=42976 As you can see in the information provided, I am using the 3.5 version of the Kernel and the problem persists and it happens at least 2 to 5 times daily. It happens more if I watch a youtube video, downoad through torrent or try to connect to any online bandwidth consuming site or app. Here is a couple of the error logs from syslog: DMA: Out of SW-IOMMU space for 490 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 517 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 561 bytes at device 0000:03:00.0 DMA: Out of SW-IOMMU space for 562 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 607 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 670 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 89 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 92 bytes at device 0000:03:00.0 DMA: Out of SW-IOMMU space for 94 bytes at device 0000:03:02.0 DMA: Out of SW-IOMMU space for 97 bytes at device 0000:03:02.0 Looking at the PCI ID I did a sort|uniq and found the following other network devices giving the same problem: 03:02.0 Network controller: Ralink corp.
