if on the chipset on my motherboard (northbridge) some of the things are bent....could this lead to restartin?

Answer 1

That is just the heatsink. Not much of a problem if bent. But it is a big problem if its base is no longer in full contact with the Northbridge chip. It could overheat and cause a restart. Check its temperature w/ temp monitoring software like Everest or Speedfan.
