  1. Woah there skipper. Punctuation and paragraphs help a lot with getting replies.

    Other than the difference in memory addressing, slight changes to the kernel, etc. there's not too much of a difference between the 32- and 64-bit O/S. Perhaps these differences are revealing a weakness in your hardware.

    It's probably a long shot, but have you tested your RAM from bootable media with a program like Memtest86+?
  2. ran some memory test useing everest with no troubles but i will give memtest86+ a try and see what i get

    running 64 bit prime on window 64 bit and the 32bit on windows 7 32 bit wonder if there is a diff in the two that may cause the problem
  5. Could be. Though you'd think that difference would translate into other having problems as well, which I haven't seen.
  6. yea its crazzy to me running really stable at 4.2 running windows 7 32 bit just dont understand why its unstable on windows 7 64 bit wondering if anyone else has this problem if so give me a yell
