I thought the BSoD would happen only when I play DDO, but I noticed that it also happens when I play Crysis. Before I installed the Maxtor 1TB (which was new), I had a Maxtor 360GB HD IDE on this system that worked fine. then I took it out and installed the 1T. When I installed the 1T it seemed fine but then the BSoD started to come. So I thought it was the hard drive because it was new and the other hard drive had no problem, I put the other IDE 360GB. The crappy thing is the same damn thing happened with the other hard drive! After a couple weeks of reading other peoples 0x000000f4 errors I finally decided to come here and post. Now I think its safe to say that I ruled out the Memory reseating them, moving them, pulling all but one out at a time, and also running Memtest. I'm up for any wacky suggestions.
