How to Restart Services on Remote Server in Powershell

I am trying to do something very simple but have lost my way. I have this script that works almost perfect. It goes into a list of servers checks for 2 services and checks if they are running. Then, it generates a list of servers that are running or stopped. Now, what I need it to do is to restart the service when it finds that it is stopped...

$Computers = Get-Content -path C:\computers.txt
$Computerobject = $null
FOREACH ( $Computer IN $Computers )
{
    TRY
    {
        $Services = $null
        $Services = (Get-Service -Name 'CrystalToPDF','Bradware - BoxUploadService' -computername $Computer -ErrorAction Stop | Select-Object Status, Name, DisplayName )
        Add-Member -InputObject $Services -NotePropertyName ComputerName -NotePropertyValue $Computer
        $ComputerProperties = [ordered] @{ComputerName=$Services.ComputerName; ServiceName=$Services.Name; Status=$Services.Status}
        $Computerobject = New-Object PSObject -Property $ComputerProperties
        $Computerobject
    }
        CATCH
        {
            Write-Host "Both services are not installed on $Computer." -ForegroundColor Red
        }
}
