Which operating system ?????.....
The HP Recovery Partition that comes pre-installed on most new HPs is like built-in insurance if your system becomes unstable or fails.
If the problem is severe enough, you may not be able to start the HP Desktop Recovery Manager from Windows but you can start it manually by following the steps below.

Disconnect all peripheral devices and power on the computer.
Press the F11 key after the computer first powers on to start the HP Recovery Manager.

Follow the on-screen instructions to back up recoverable files on the hard drive to an external drive or media.
Continue following the instructions to recover the hard drive to its original factory condition.
Click "Finish" when the recovery is complete.
Reconnect devices and reboot the computer.
Reinstall software and update Windows and HP to current settings.

it sounds like the SD card reader has failed. This fortunately is a quick, semi-cheap (~$20) fix. You can purchase a media card reader that plugs into the USB on your system for about 20. If your system is in warranty, I would contact and see if they could schedule a replacement part or a depot fix/tech call to replace the failed drive

Yes, use balanced cable to the PA system and use a DI at the computer end.

The DI is known as a "direct box" or "direct input" and converts the UNBALANCED computer output to balanced to send toe the PA system.

you sould instal the proper driver(for XP) for the sound card,before that check in my computer-advanced-device manager- if the driver is working properly.
