One thing though now you mention it. Battle for Middle Earth also crashes on my new PC, and a couple of times it gave me an error message related to DX8, which doesn't make sense since I definetely installed DX9. My PC shouldn't be having problems with DX9, its even DX10 compatible.
New development here. I have 2 1GB RAM sticks in my PC. I took the one in slot 2 out, tried playing with just the slot 1 RAM. Still crashes. So I put the slot 2 RAM back. Then, I tried swapping the two RAM sticks around. This left M2TW crashing as normal, but also gave me blue screens when doing things like browsing the internet, even starting the PC up once.

The reason I am doing this with the RAM is that I heard blue screens tended to be caused by faulty RAM. So, my last plan is to remove the RAM that was originally in slot 1 (now in slot 2), and put the RAM currently in slot 2 into slot 1. This may prove that the RAM beginning in slot 1 was faulty. I will try and see...
