Chromium, at least, is going to force you to start swapping if you've only got 4GB of RAM in the machine, so I'd check smartctl and see if the drive you swap partition on is having any trouble. I'd also suggest removing the NVidia card, going without X for a little while[1], and see if you can reproduce the issue[2]. I'd guess that it's the unlocked core that's the source of your woes, though. Not all X3s are so labeled just for market segmentation. [1] Only because your onboard video is ATI, and flipping between ATI and NVidia configurations for something like this would strike me as too much a hassle. [2] Only because limiting the number of active components helps when troubleshooting hardware issues. I once found a sporadic kernel panic was related to a failing NIC. Another time I found it was related to an old Hauppauge PVR150 that worked fine with my old motherboard, but was incompatible with my new motherboard.
