HP Pavilion Touchscreen unresponsive

Hello, I've got a HP Pavilion All-in-One workstation that I'm unable to log into.  The issue is I can't get the touch screen to work, or an USB keyboard/mouse.  If i leave the USB keyboard mouse unplugged during boot I get the attached error, something about Keyboard error.  If i leave the USB device plugged in during boot I don't get the Keyboard error.  I've done some research on this issue, all of which require logging into windows. Since I'm unable to log into Windows I'm stuck.

So when you boot up with the keyboard and mouse connected, they do not work?

Have you tried plugging them into a different USB port? If so, wait a minute or two at the login for the drivers to install. If it sees it as new hardware, it can take a little while for the system to let you use it.

Also, have you tried a different keyboard and mouse?

If you shut down, start up and again restart, can you force the pre-boot sequence to give you a "repair" screen where you can enter Safe Mode.   Then try to reinstall the applicable drivers.

William: Correct  when booted with USB connected they dont work.  Yes I've tried every USB port on the machine, let it sit for over 10 minutes nothing.  Yes I've tried a different keyboard/mouse.

John:  I cannot get to the ALT boot menu, can't use hot keys to get to menu.  Is there another way to force system to boot to ALT boot menu?

Thank You both.

I thought when you first restart, there would be information on the screen. Safe Boot is an option, at least for our Lenovo Machines.

Restart again and at the instant it is beginning to restart, press F8 repeatedly. That may get you into Safe Mode.

Also, if no screen and nothing works, remove the hard drive to recover the data, replace the drive and reinstall Windows.

John my keyboard doesn't work so pressing F8 is not an option.  I did try this prior to posting the article it didn't register, booted into windows.

Thank You.

If an alternate keyboard will not work, you will have to get the machine serviced to reinstall Windows and determine if the keyboard needs to be replaced.

You need a keyboard on any machine to install Windows.

Sounds like you've got some kind of hardware failure. How old is the machine and is it still under warranty?

ManieyaK_CSSPAuthor Commented:
Its about 5 years old no warranty.  Yeah that was my orginal assumption a keyboard is needed to reload windows. What about a networked approach?

ManieyaK_CSSPAuthor Commented:
I'm pretty much stumped I don't think there's much that can be done. I'm thinking it hardware failure as well.

JohnBusiness Consultant (Owner)Commented:
You need a keyboard to get started and if none, and the machine is that old, maybe it is time for replacement.

Is there any way you can open it up to inspect the motherboard? If it's hardware failure you will probably find some blown capacitors.

I will attempt to check for blown capacitors

since it is an AIO - i would disconnect the AC power - and hold the power button for 20 sec
then connect usb keyboard + mouse ( test also on different ports) and reconnect AC - power on now
you can post the model , so we can look up the manual

Everyone thank you for the comments.  I tried another USB Keyboard/Mouse left it plugged in for about 30 minutes now working.  I dunno why but my wireless keyboard/mouse wouldn't work, but a corded USB keyboard/mouse worked.
