Thank you stuart. I'm afraid your solution does not apply to me. My freezes are instant, without any sluggish or strange mouse or keyboard behavior, and the system locks completely, including low-level functions such as Ethernet pings. I'm also not using an Nvidia card, nor any proprietary driver, and my PCI express slot is empty.
