What do you mean by "seeing really big temperatures"? Was the computer in working condition then? Was it burnet - smoking out of the cabinet?

Anyway - I guess you have OC your setup way more then it could handle, and now the MB is fried too.

I didnt overclock at all it was just working for many hours and the thermal paste was old

Please elaborate excactly what you did see and what actions you took.
