Out of interest, is your disk a physics HDD or a SSD? How much RAM do you have?
The freezing could be some disk thrashing going on as you're filling up the RAM and the CPU is having to resort to using the (slow) hard drive to store the overflow.
Looking at your error logs, Windows appears to be having some kernal issues, as you've got two versions running on there I would be tempted to blame some bad sectors on your disk. Might be worth spending £50 buying a new SSD off Amazon and trying it out to see if that fixes anything. If not you can always send it back...
