Powershell New-object Command not reconized am i missing a module?

Question

I want to configure high trusted app for app dev in SharePoint, end to do so i need first to insert some commands in the powershell editor like :
    $publicCertPath = "C:\Certs\HighTrustSampleCert.cer" 
    $certificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($publicCertPath)
I am using windows PowerShell on Windows Server 2012 R2 which includes Windows PowerShell 4 that includes by default the new-object cmd-let... I don't understand though, why doesn't my system recognize that command .... Each time i am getting the following
error : New-Object : The term 'New-Object' is not recognized as the name of a cmdlet.
Every time i open power shell it displays me the following error :
*select : The term 'Select-Object' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.

    + FullyQualifiedErrorId : CommandNotFoundException*
I thought that was normal until today... does it have any relation with the error?
And here is the hole (new-object) exception stack:
*New-Object : The term 'New-Object' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or

Can anyone help me please?

Answer 1

the new-object cmdlet is not defined in a module.
Try this:
reboot your computer
start the powershell console
type a new-object command without parameter
this is what happens when I do that:
PS C:\Users\Al> new-object
cmdlet New-Object at command pipeline position 1
Supply values for the following parameters:
TypeName:
what happens on your system?

Aren't you able to see a simple semantic error?
I told you almost never post any technical text, just vague and imprecise generalities.
When you try to post something technical, you post a rubbishellian text like this one, typical of a decrepit old vb scripter 101% PowerShell ignorant.
Certainly, you are the worst rubbishellian I met in this forum.
@admins: will you please, inhibit the reply button for this rubbishellian forum member? He should just ask questions; never answer any of them.
Your post above is off-topic in this thread, as it is a personal attack on me that contains no information likely to actually help the OP with his problem.
I was not aware that you are the arbiter here of what is appropriate to post, especially given your collection of abusive posts and banned accounts.
