Hello i have hp rp5000 pc which have AGP port onboard but when i put graphic card in it it doesnt recognized it. I tried with another hp rp5000 bios but it doesnt work anyway-is there anysolution?


Erm, although the slot is labelled AGP1 (HEY HP Accelerated GRAPHICS Port 1 ???), it is not for a graphics card.
It is intended for an enhanced USB card that adds additional USB ports as well as 12volt and 24volt outputs.
The RP5000 was designed to be a POS (point of sale) unit and the additional ports were for devices such as barcode readers, handscanners and card readers to be plugged into.

Greetings....

Please try to check if your USB port both rear and front USB port are not defective. Most common problem of defective usb ports are when plug your usb devices it won't recognize the device you inserted. So to make sure that your USB Ports are not the main cause why your computer won't recognize devices you inserted.

USB not recognized during printing and scanning


Some motherboard or operating systems have problems if you leave usb devices plugged in. They don't recognize that the device is still there and ignore it. These are referred to as "Legacy USB devices". There are a couple of things to try.

Make sure the problem isn't the printer if you can. If you have another computer just plug it in long enough to for the operating system to recognize something has been plugged in.

On this computer giving you the problem. unplug the usb cable and insert into a different USB port. Usually this is enough to "fix" it and make it usable.

Next is to unplug the usb and reboot the computer a few times. Then insert into a different usb port.

Past this point if it still isn't working then you need to go to control panel-system-hardware manager-usb devices and delete all entries under the usb header. Then reboot. This forces the operating system to find all the usb ports and reinstalls the drivers. Then plug in the usb and it should work again.

Keyboard, mouse, front USBs,DVD recorder not working


It sound like your USB Ports is the problem. Go to the Hardware manager delete the USB Ports and then shutdown and power back up.
The system then should reinstall the USB Ports and associated drivers. If not the USB Ports were probably fried by the power outage.
