Each dump is different.
cfrmd.sys - Comodo Firewall
sidebar.exe - Windows Sidebar
tcpip.sys - ??
ntkrpamp.exe - ??
Try uninstalling Comodo Firewall, see if that helps. If not then backup your data to be safe then do a Repair Install. If you don't have a Windows install CD, do you have a manufacturers Recover CD? If so, use it.
With Vista, you may also have a Recovery Partition on the hard drive you can use to restore the computer to it's factory new state. This will wipe out everything, data and programs you've installed so make sure you backup your data first.
What is the make and model number of the computer? We may be able to find the Users Manual online which will tell us how to get to the recovery partition (if there is one).
