I have been trying to install WIndows XP Pro Corporate Edition. It gets formatted to NTFS and restarts then with 39 minutes left, a blue screen comes up that says: PAGE_FAULT_IN_NONPAGED_AREA ***Stop: 0x00000050 (0xFFFFFFFC, 0x00000000, 0x8053E407, 0x00000000) I came upon this: http://support.microsoft.com/?kbid=171003&sd=RMVP It says it is a RAM problem that can be located in several areas, including the secondary RAM cache, the video RAM, or the computer's main memory!! I thought there was only one type of RAM! It says to disable all caching on the computer, including the CPU cache and L2 cache, in the computer's CMOS settings. Then it says to refer to the computer's documentation regarding the computer's CMOS configuration tool. How do I do this??? How do I disable all caching? The computer wont even start. I was installing windows and it never completed. I get a black screen at startup if I dont continue installation, and if I do continue, I get the same blue screen over and over! Can I disable caching in MSDOS? How do I do this?? Please help. I'm working on a HP Pavilion dv1000 laptop.
