Recently built this system and installed Win7 on it. The computer runs fine, except for when I play Lord of the Rings online. It can run for hours and then crash, or it can crash right away. I went thru the forums here and found the place where it says how to analyze the crash, starting with malware etc. I did find one malware entry in the registry, which I cleaned, but I am still getting the crashes. I finally analyzed the dump file and am posting it below. Any help would be appreciated. If more info is needed (more system stats, etc) let me know.

Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arg1: ffffffff80610000, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff80002ea9e60, If non-zero, the instruction address which referenced the bad memory
Arg4: 0000000000000005, (reserved)

Oh, I forgot to mention that I ran Memtest all night, and it seems like the Ram is fine.
