I just purchased a p4b533 along with p4 2.26b and 512 crucial. I am trying to install win xp but I keep getting errors. The errors occurs when it tries to copies files to my hd for preparing the install. First, the files won't copy over and then a blue screen pop up. It says, "Windows has been shut down to prevent damage to the computer."(Something like that) Sometimes the error is (PAGED_IN_NONPAGED_AREA) or (NTFS.SYS - error cause by this file). I dont' know, I tried with different rams, different hd, I put the chip in a different motherboard (which ran perfectly). I got it to install once but I had to drop the cpu speed down to 1.84 to get it working. But it became very unstable, just kept crashing over and over again, until I wasn't able to load xp anymore. Anyone can help? Much Thanks. 🙁
