Hi guys, I know you're likely sick of Physical Memory Dump threads, but I'm completely stumped on this one. Windows XP Pro, SP3: physical memory dump every time I start the computer. First "fixed" it by simply running only one of the two sticks of RAM, but now it dumps even with just one. Windows 7 HP: works just fine. Clearly, the hardware seems to be just fine. Otherwise, the Win7 partition wouldn't work - right? If this is something you could help me with, please let me know if there's any other information I can provide to aid in the troubleshooting. Thanks!
