The laptop didn't come with any backups or restore disc's so I hang my head in shame and plead to anyone how may know what device this could be and where I can get drivers.

You need to download:

HP ProtectTools Embedded Security Module and Infineon TPM Driver "SP25985" and extract it. The driver is in the TPM folder. You should be able to install it by just pointing to the directory.
