Anyone know what kind of problems are caused in XP home by upgrading my processor from a 2.4B to a 3.0C? The system POSTs fine and boots, but my IE and several programs error out at startup (IE depending on what site I go to also, some sites are OK, but my normal weather.com home and Anantech sites cause an error report screen ), and I sometimes get the bsod upon shutdown with some type of _IRQ_ message. Do I need to do a repair to get it to work? TIA.
