@Jaide2,

Welcome to our HP Community forum!

Are you referring to the HP Compaq dc7900 Convertible Minitower (CMT)?

If so, that system’s 365-watt power supply should be more than sufficient for the Nvidia GeForce 310, which has a very low power draw (around a 31-watt TDP).

That said, the GeForce 310 is an extremely low-end and outdated GPU. In fact, your system’s integrated Intel graphics (especially if you're using a Core 2 Duo E8xxx or Quad Q9xxx CPU) may actually outperform the GeForce 310 in most cases.

Anyway, if the card isn't being detected:

• Try reseating it securely in the PCIe x16 slot.
• Make sure your monitor is plugged into the GPU and not the motherboard's video output.
• Check BIOS settings to see if there's an option to prioritize PCIe graphics over onboard.
• Test the card in another system if possible to rule out a dead GPU.

Let me know your exact model (e.g., dc7900 CMT, SFF, or USDT), what CPU you're running, and which video output you're using (VGA, DVI, etc.), and I’ll dig in further!

Kind Regards,
