BTW if you dont know what BSOD is short for Blue Screen Of Death
We know...
We will need the information from the BSoD. Follow these instructions to disable the automatic reboot on error feature in XP.
Right click my computer and select properties
Select the advanced tab
Press the Settings button in the Startup and Recovery frame
Uncheck "Automatically restart" and leave the menus with OK.
We will need the STOP error code and any filenames mention on the BSoD. See the image below for an example BSoD with the info we need marked with red boxes.
