I have a Toshiba Tecra M4 that keeps popping this message up when I try to install Windows XP. The laptop originally had the Tablet XP OS on it but the factory image was erased. I work for an accounting company and this is a little project that they gave me to work on. I originally took it to an authorized Toshiba repair shop and they ran a diagnostic on it and told me all of the hardware was working properly. The warranty covered hardware but not software so they sent me on my way. I can get through a good percentage of the install (I can format with NTFS and run the setup) but when the setup is getting close to finished I get the BSOD. The stop error is 0x00000050. The version of XP that I am installing has SP2 on it. Any help would be greatly appreciated. Thank you.
