Question about Compaq Evo D500 PC Desktop

1 Answer

I have four Compaq EVO D510 computers that all have the same problem. They are used computers that were pulled out of an existing site. I have a USB mouse & keyboard connected to the computer (no ps/2 inputs). These devices work fine in the boot menu but stop working after windows loads (Normal and Safe mode). I have have tried numerous keyboards and mice and different combinations of usb ports with no luck. I have also tried enabling and disabling the network server mode. There are no error codes. The usb controllers/drivers would be the first thing that I would check but since I am unable to get a single keyboard or mouse to work I am unable to get into the device manager.

Hi sdd555,

Restart the computer after plugging the USB keyboard into a different USB port, or remove the keyboard in Device Manager and then refresh the system to work around the issue. This will cause the device to be re-enumerated and the driver will be reloaded.

Good Luck,

Mark

PCI simple Communication Controller


Drivers are here:
http://h10025.www1.hp.com/ewfrf/wc/prodTopCategory?product=96027&lc=en&cc=us&dlc=
Just click evo d510 cmt, then download drivers and software.

You should now be at a page that lists all of hp's drivers for your system.

I think PCI simple Communication Controller would be your modem, which I saw on that page, and also the driver for your ethernet controller.
