Windows XP wont shut down!

[Jay]

Can anyone help me? Briefly, here is my problem: I tried
installing Norton Antivirus onto my Windows XP Pro
machine. Right after I installed it many things stopped
working, so I uninstalled ALL Norton devices. However,
that did not fix any of the problems, so I reinstalled
windows, that too did not fix anything. This is what is
happening: When I am in Internet Explorer (or any program
with a scroll bar) the page scrolls very slowly.
Secondly, my computer will not shut down or go into
hibernation or sleep mode! The only way that I can turn
it off is by holding the power switch. When I try to shut
down I can briefly see this Blue error hexadecimal
screen, but I cannot see it long enough to see what the
error is. Right after the blue screen my computer
restarts.

Can someone please help me with this problem? thanks a
lot.

Hi Jay,

System Restore comes to mind, here. Other than that for your latter
mention:

This edit controls whether Windows should automatically power down or reboot
your computer once it has finished the shutdown process.

Power Off or Reboot After Shutdown (Line 76)

This edit automatically ends tasks and timeouts that prevent programs from
shutting down and clears the Paging File on Exit.
