Does your machine shut down suddenly? What do the Event id/s 37 (Kernel Processor Power) and 219 (Kernel-PnP) say? Click on one of them in EV and open the log to read it. Again, you may want to check for an update for your chipset. This can be found on the website for your machine's maker. I assume this is a laptop?
It's impossible for a stranger without access to guess whether it's your cooling pad or not. But to be safe, maybe unplug it for a little bit while you're trouble-shooting. You should monitor the temps, using something like HWiNFO64. Laptops generally run hotter but you should check for too hot as thermal events can result in sudden shutdowns.
The DCoM warnings may usually be ignored. If you open one and it says "CSLID unknown" under Event Viewer/Details tab, you can delete the registry key and prevent future warnings from cluttering your Event Viewer. I made a little video some time on how to do this via regedit--hit "Find Next" under Edit b/c chances are there are multiple keys.
