Games not Opening?!?

Hey, im new to this forum and i signed up because my pc games aren't working. Battlefiel 1942, Battlefield Vietnam and now Need for Speed Underground 2. I'm wondering if it's just a coincidence that these are all E.A games but meh. Every time i try to open these games it comes up with this message that the exe. ill say for need for speed. speed2.exe has encountered a problem and it will come up with the dont send or send error report. This keeps happening and i do not no what to do. If anyone has any ideas it would be much appreciated.

Thanks.

P.S - If none of you can help i plan on formatting my computer this weekend.
