Hi everyone. I have just finished upgrading my old computer with an intel pentium 3 600mhz cpu. The upgrade went ok but when i try to use internet explorer, windows live messeger or any other web based application the program will just crash with a message saying "This program has encounted a problem and needs to close". It never use to do this with my old celeron. Could this be a problem with the cpu? or do i just simply need to reinstall windows? Any suggestions on what may be wrong with it would be awsome. By the way when i turn on my computer the bios says it is a 600EBMHZ what ever that means.
