I hope someone has a fix for my problem. I have a NVIDEA FX 5200 and have two monitors attached. The card is working but my computer is running on defalt and won't let me use any of the controls.I have done all I can think of. I took the card out and put it back. Can't reinstall drivers because hardware is not found with a code 45. Any help would be welcomed.

Brief checklist and next steps based on the thread: has an add‑in video adapter that Windows is treating as not present after an OS reinstallation; already steered the thread toward Device Manager and display settings. The behaviour described most often comes from one of three root causes: the card is not being enumerated by the motherboard, Windows is using the generic driver because required system/chipset support is missing, or the adapter has a hardware/seat problem.

Try these steps in order:

  • Power down, unplug, open the case, and reseat the card. Ground yourself to avoid static. Inspect the card edge for bent pins, corrosion, or debris and check that any supplementary power lead (if present) is connected.
  • Confirm BIOS video priority: force the board to use the expansion slot instead of any built‑in video, then save and reboot.
  • Boot to Safe Mode, remove all display adapter entries (use “show hidden devices”), uninstall drivers and software from the vendor, then reboot and let Windows re‑detect the hardware.
  • Before reinstalling the video driver, install the motherboard/chipset drivers for the system so the bus is fully supported; then install the correct manufacturer driver (use the vendor’s official driver page).
  • If Windows still reports the adapter as not physically present, try the card in a different PC (or try a known‑good card in this PC) to isolate a motherboard/slot issue from a card failure.

Relevant references: Microsoft’s Device Manager error codes and guidance can help interpret the “device not connected” status (). For official drivers, start at the GPU vendor’s download page (NVIDIA driver downloads).

Cautions and final notes: avoid third‑party driver cleaners unless necessary; clearing CMOS or updating the motherboard BIOS is a sensible final step before replacing hardware. If the adapter works in another machine, the problem is the motherboard/BIOS or OS configuration; if it fails elsewhere, the adapter is likely faulty.

what type of computer are you running? And where there any problems that occurred just before this happened?

Right-click your Desktop --> Properties --> Settings --> (You'll see two boxes numbered 1 and 2 in a shaded area.) Click number 2 --> Right Click --> click "Attach" --> change the resolution to match monitor number 1 or whatever resolution you want it at.

let me know if this helps

Under settings I don't have the two screens to chose from anymore.There is only one screen and Display(default Monitor) ON. It is like my computer doesn't know that I have a NVIDIA FX 5200 installed,but it is installed and connected to two monitors.

Right Click "My Computer" (either on your desktop or Start Menu" --> Properties --> Hardware Tab --> Device Manager --> look to see if there is a question mark beside your Graphics card --> if so right - click and install.

if not or if you don't see it at all let me know

In Device Managment (show hidden devices)
Display addapeers
NVIDIA FX5200
Properties
Currently this hardware device is not connected to the computer (code 45)
But the card is connected and working with both screens showing the one desktop
