ok,
 
for the past week my computer has been causing some problems when being turned on. ill turn it on, then it well go fine until the windows loading page. there instead of continuing, most times it will flash this blue screen with a whole bunch of writting but it goes to fast to read. then it will restart and bring me to a page that says your computer hasnt been shut down right or something and theres options of safe mode, safe mode with networking, last config or normal. when i chose last config everything works fine. but this happens pretty much every time i start up my machine. does anyone know how to fix this? id also like to add i have windows xp home
 
the error is:
 
STOP: 0x00000050 (0xF778A800, 0x00000000, 0xf7775051, 0x00000000)
