How to use multiple classes in Powershell

Hi Everyone,

i'm using following code to retrieve page file information, it gives the page file information but not computername. It says that

Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty. Supply an argument
that is not null or empty and then try the command again.

When I tried to use the class Wmi32_computerSystem  but it is not giving page file info. I need page file info and computername both

Could anybody help me out?

$computers = Get-Content -Path C:\servernames.txt

foreach ($computer in $computers)
{
 
 Get-WmiObject Win32_PageFileUsage -computername $computer |Select-Object Name,AllocatedBaseSize,PeakUsage,CurrentUsage

}
