Hello everyone!!! I'm fairly new to all of this. My ex husband was a wiz at computers so I'm learning this stuff myself. A couple months ago my computer started re-setting itself during use and would not comeback on for a period of time so I figured maybe a fan had went out and that it was overheating, so I took a look and it appears the fan on the cpu was not working. I removed the cpu, re-installed and changed the fan but now nothing boots up. Before buying a new cpu or taking one out of one of the other computers should I try to re-install the cpu with a new coat of thermal paste? Do you think maybe the cpu is fried? Any help or suggestions are welcome....
