today i recieved my new heatsink.. when i was tryin to take out the old one's mount.. i scratched my motherboard prett bad around the cpu....my new heatsink didnt fit.. and i broke old ones mount when i was trying to take it out.. so i decided to put in the stock heatsink that came wth my cpu... Well it didnt fit perfectly.. it was little lose but kind of tight... i also put in 1gig extra ram and when i turned power on... terrible burned smell came outta pc... i couldnt figure out where it was coming from.... on my monitor it was black screen and it said no signal... Did i burn my cpu? how can i test my cpu?? can i put it on a different computer to test it?? How do i know if it is the MB burnt my cpu?? would the scratch cause it? it was kind of around the CPU... Is it possible that my MB got burned because of the scratch? I just wanna figure out what was burnt so i can replace it.. thanks!
