Computer Crashing During Start-Up After Changing Cooling

[TheStoryteller]

So, in the past few months, while playing graphically intensive games, my computer has shut down without warning. It seemed to be a heat-related problem with my CPU, so I thought I should upgrade the fan.

I ordered the new fan, and it came in the mail. Being the peon that I was, I unscrewed the fan mount (http://tinyurl.com/lvd3jz3) to take off the fan. When returning the mount, after realizing it was unnecessary to remove it to un-clip the stock fan, I noticed that only two would go in. For some reason, the bottom screws could no longer be screwed in. On closer inspection, I noticed that the holes that the screws were supposed to go into no longer had the holders that they screwed in to. They didn't fall out, so I have no idea what happened.

When attempting to turn on my computer, it will run for around 10-15 seconds, before shutting off completely. Not to mention, it has gotten to the point where it gets to the MSI splash screen, stops progressing through start-up, and doesn't boot up to Windows.

[Update] As this seems to have caused confusion for obvious reasons, I DID add a new layer of thermal paste after removing the old layer. Also, there is a reply to one comment, which explains what is wrong with the screws a bit better.

I don't see anywhere in your steps that you cleaned your CPU and applied new thermal paste

Forgive me, I did indeed clean the old thermal paste off, and apply a new layer of Arctic Thermal Paste.

Your CPU is overheating, do what tachybana says and fix the screws.

I did apply thermal paste, I just forgot to add that to my explanation. And, I don't see any way to fix the screws. It's hard to explain.

They don't connect directly to the motherboard. There are little "mounts" or "holders" for the screws which they screw into, which are like, under the motherboard, and two of them just are no longer there. I have no idea how I would fix that problem.
