My laptop keeps freezing or restarting itself

[nlaurora]

The title pretty much explains it, and I have no clue what to do. I'm not a pro at working with computers, but I just don't have the money to go and get my laptop fixed.

Problems:
-locking up soon after I turn it on
-restarting repeatedly
-was saying it found new hardware 'IEEE 1394'

I tried deleting the microcode update device because it was showing an error, but the problems still persist. What should I do?

Have you check to see if the fan is turning on when you start up?

Also try running hard drive test. you can find the test as follows

TechSpot OpenBoards > Hardware > Storage and Networking
Drive diagnostic utilities compendium

you can use one of those or try the computers on board diagnostics.
