Today I moved all my hardware from one case to another very carefully. So when I booted up my computer nothing would come on the screen, the monitor says "No screens found" and thats all that is there. So I check all the cables and it was all ok. Untill my friend pointed out that one of fans was not working and it turned out to be that the little fan ( the one under the cpu) was not spining and could the chip could be fried :'( are those chip replaceable or do I need to buy a new MB ???

TIA
