Hello all. Any help with this matter is greatly appreciated.
I have a bsod. I have tried to reboot in safe mode but won't work. I have installed operating cd and turned computer on with no luck. It seems like its starts to run and stops. I am able to hit the f keys but nothing will work on keyboard after that. The windows recovery page will come up on f8 but am unable to arrow up or down.
Windows 7
64!bit
Amd Athlon x 2

Thanks
Mike

See here: "Stop 0x000000A5 the ACPI BIOS in the system is not fully compliant with the ACPI specification"

If that doesn't help, is this a Desktop or Laptop?

If Desktop, power off and unplug the power cord.
Open the case and remove the CMOS battery (small silver about size of a quarter).
Press and hold the power button for 10 seconds.
Put the CMOS battery back in.
Plug in the power and power up.

You will get an error about CMOS configuration so press whatever key will take you to Setup.
Find the key or selection to load Defaults then save and exit.

See if you can get to the Advanced Boot Options menu via F8. If so first select Last known configuration that worked. See if that does the trick. If not, select Safe Mode with Networking then from the prompt, type chkdsk /r and press Enter. You will get a message similar to this:

Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)

Enter Y then reboot. chkdsk will run at boot. Be patient as it can take an hour or more to complete.

See if that helps.

Thank you for responding. I have a toshiba satellite laptop. I am able to get to the inside h20 setup utility screen but not able to arrow to any selections. No keyboard function other than f keys. I am also Abe to get to the boot page but not able to make any selections. I'm willing to try anything at this point. Any additional help is greatly appreciated.

Sounds like the keyboard may be defective. Try connecting an external USB keyboard, see if you can do anything from there.
