Unknown device is likely 3D Driveguard (accelerometer):

My pc is windows 7 32 bit

[Huffer]

Of course. That complicates things substantially.

@Paul_Tikkanen

Any suggestions?

@Huffer

All the drivers also contain the 32 bit files except the audio and graphics drivers.

What I don't know is how you know from the info that was posted, that it is a HP 250 G4.

I've tried different ways to decipher hp tn c125, and that descriptor gives me no idea what model that is.

I googled it in various combinations, found a site where they were selling it with that odd designation and it also indicated it was a 250 G4. Its actually TPN-C125.

OK, thanks.

Then all of the drivers you posted will work on W7 32 bit.

Graphics (which I guarantee is also missing, as it doesn't plainly show up in the device manager as missing), is a different kettle of fish.

Here is the link to the W7 32 bit graphics driver for the celeron processor your notebook has...

3rd one down on the left...

If you want to install the 32 bit audio driver designed for your PC, then accept the agreement, download and install the 1st driver on the list at the link below...
