Oh, indeed, I'd had my share of headaches caused by Thunar before this freezing problem appeared. I'm glad Thunar 1.6.11 doesn't crash every time I rename a file, like 1.6.10 would. Anyway, Thunar has a feature set that I'm happy with and I don't think it can be blamed for the freezing. It happens even when Thunar is not running in daemon mode in the background.

The symptoms in Windows 7 are much more troubling: the entire system just reboots itself without any obvious reason. However, I have no idea if those crashes are related to the freezes in Debian. In other words, they could very well be. I think they began occurring around the same time, but for all I know, it could simply be a case of Windows crashing because it is Windows.

The ASUS UEFI BIOS Utility reports CPU temperatures between 25°C and 27°C, which corresponds to the value of the CPU's "Physical id 0" sensor as reported by `sensors` when no resource-hungry software is running. The BIOS utility doesn't monitor the temperature of individual CPU cores.

I'm fairly sure it's never been changed. The machine was assembled less than sixteen months ago and I haven't touched the stuff.
Thanks for all the support. I'll try to assemble a list of software that suffers from the freezes and look for a pattern. I probably won't have time to come back to this until next weekend, but please let me know if there's anything else I should look into.
