I have a thinkpad lenovo r61.
Yesterday, I deleted some registry files named Upperfilters and lowerfilters on my computer to get my cd-drive working again.
WHen I re-booted, my touchpad and my keyboard no longer works.
It's not that they are disconnected or anything because the keyboard works fine in BIOS and even when I'm in windows and just trying to use the Fn shortcuts on the Lenovo keyboard.
However, I cannot move my cursor not can I type or do anything with the actual windows xp.
When I shut down by pressing down the power button,
it sometimes shows a blue screen of death where it says an error in
WHat do you think the problem is?
