    I'm getting this error when I reboot to defrag system files with PerfectDisk (version 10 but also tried 11). This is the only time I see this (or any other) blue screen error.

    System:
    AMD x3 720 (unlocked 4th core and clocked to 3.2GHz)
    Asus 785G board (w. gfx)
    4 GB OCZ DDR2-800
    2x 1TB Hitachi HDD

    Microsoft claims it is a hardware error - RAM, MB or mismatched memeory modules. None of which should be affected by Perfect Disk upgrades.

    But if you look at their detail info it could result from perfect disk trying to check more hard disk than exists. Still not a solution (other than a different optimizer, I've stayed with perfect disk 6 because all the latter ones were clunkier or had issues.)...

    From MS
    To determine an approximate cause, examine the parameters at the top of the STOP screen:
    **STOP 0x0000007F (0x000000XX, 0x00000000, 0x00000000, 0x00000000)
    UNEXPECTED_KERNEL_MODE_TRAP
    The most important parameter is the first one (0x0000000X) which may have several different values. The cause of this trap can vary, depending on the value of this parameter. All traps that cause a STOP 0x7F can be found in any Intel x86 microprocessor reference manual as they are specific to the x86 platform. Here are some of the most common ones: Values Meaning ---------- -------------------- 0x00000000 Divide by Zero Error
    0x00000004 Overflow
    0x00000005 Bounds Check Fault
    0x00000006 Invalid Opcode
    0x00000008 Double Fault

    Yeah, I've read MS's KB's on the error. I should add that if I reboot after the BSOD, PerfectDisk will attempt to defrag sys files on C: except that it stops and says something to affect that it cannot have exclusive access to C:. I'm assuming that another driver is locking access to the drive. The only thing that really jumps out at me is that I am running in AHCI mode and had some issues originally getting the ATI AHCI drivers installed. I would prefer not to switch back to IDE mode...

    Finally got it figured out... It wasn't an AHCI issue. Here is the fix from PerfectDisk (although it didn't work for me): PerfectDisk Software Support | PerfectDisk.com

    I ended up having to install the demo for v11 and then uninstall it and install 10 again.
