Windows XP-problems

I have 2 problems and cannot find any articles on how to
solve it.
I am running Windows XP professional; IE version 6.0; i am
connecting thru a DSL line; yesterday, i get 2 error
messages and then my pc restarts automatically:

One message displays in the ie.exe application error: 'the
instruction at 0x022e37a0 reference memory at 0x022e37a0.
the memory could not be read'

2nd error: displays; 'generic host process for Win 32
services has encountered a problem and needs to close. we
are sorry for the inconenience. Generic host process for
win32 services; windows myst restart because remote
procedure call service terminated unexpectedly'

can someone help me with this ASAP?

thanks
