That is the message but that site is for windows xp and it dosen't happen and start up. It only happens when I watch short movie clips. Thanx for the effort though.
1/ Have you got the latest Media Player?
2/ Could be a codec problem. More likely codec version than absence.
3/ Video driver problem. Have you got the latest version?
NMI ("Non Maskable Interrupt") is similar to PIC interrupts but it goes to CPU or to other controller that is ISP. To resolve this error message you need a repair tool that can easily fix issue related to your PC such as system errors, cleans Windows error, restore settings, blue screen of death etc.
