I recently bought a new Toshiba Satellite A505-S9509. The system has a Intel core 2 duo, 4 G RAM, 500 GB HD, 64 bit Vista home .premium pre-installed. I can run 64 bit Internet explorer without problem. But 32 bit IE crashed and almost all other programs crashes when launched except MS Word 2003. The message was :the program is not responding". Even MSN live, IM crash. I tried to install XP as 2nd OS but got an error message when starting the CD. It doesn't look like I have any option but to format the HD and install XP. Is this common problem? Any suggestions?
