I'm betting you have more than one hard drive, so $computerHDD is an array and so is $computerHDD.size and $computerHDD.FreeSpace, so you would need to do a ForEach($HDD in $computerHDD) and insert a loop in there (or something along those lines).

Here is what I would update your script to:

$compinfo = @()
$computerSystem = get-wmiobject Win32_ComputerSystem 
$computerBIOS = get-wmiobject Win32_BIOS 
$computerOS = get-wmiobject Win32_OperatingSystem 
$computerCPU = get-wmiobject Win32_Processor 
$computerHDD = Get-WmiObject Win32_LogicalDisk -Filter drivetype=3 
$colItems = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "IpEnabled = TRUE"
# Build objects
ForEach($HDD in $computerHDD){
    $compinfo += New-Object PSObject -property @{ 
        PCName = $computerSystem.Name 
        Manufacturer = $computerSystem.Manufacturer 
        Model = $computerSystem.Model 
        SerialNumber = $computerBIOS.SerialNumber 
        RAM = "{0:N2}" -f ($computerSystem.TotalPhysicalMemory/1GB) 
        HDDSize = "{0:N2}" -f ($HDD.Size/1GB) 
        HDDFree = "{0:P2}" -f ($HDD.FreeSpace/$HDD.Size) 
        CPU = $computerCPU.Name 
        OS = $computerOS.caption 
        SP = $computerOS.ServicePackMajorVersion 
        User = $computerSystem.UserName 
        BootTime = $computerOS.ConvertToDateTime($computerOS.LastBootUpTime) 
        IP_Address = [string]$colItems.IpAddress 
        MAC_Address = [string]$colItems.MacAddress 
        Default_Gateway = [string]$colItems.DefaultIpGateway 
        DNS_Domain = $colItems.DNSDomain 
        DHCP_Enabled = $colItems.DHCPEnabled 
    }
}
$compinfo | select -Property HDDFree ,HDDSize ,Ram ,OS ,CPU ,SP ,IP_Address,Mac_Address ,BootTime ,DHCP_Enabled

I ran that on my machine and it ran without errors.
