dell xps 13 random shut down

I recently purchased a new XPS 13 9560 from dell website(i7 8th gen, 16gb, 256gb, qhd).

It's just been a couple of days i got my laptop, and it randomly shuts down and restarts(sometimes).

On going through the windows log it showed-

"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 

{D63B10C5-BB46-4990-A94F-E40B9D520160}
and APPID
{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
to the user DESKTOP-8KFL948\MOKSHITH KUMAR SID (S-1-5-21-2010018383-2785168832-2268794304-1001) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool."

Also it shows "

The Dell SupportAssist Remediation service failed to start due to the following error:
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail." 

and "The speed of processor 4 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 27 seconds since the last report."

And also the laptop shuts down every time i close the lid, even after changing all the necessary settings.

It's a 1600$ laptop and is really annoying to get this kind of product. I'm a grad student and i really have no time to run through this.

Please do look into the matter and help me with the issues.
