I know this is of little help to you, but I had the same problems after installing an update from god old Microsoft. This update devastated my system and despite several attempts to fix it I eventually bought a new computer. I was running Windows 7 HP at the time and even went through un-installing many of the recent updates I had on the machine until I found the one causing the problem, but after un-installing it the faults kept returning which is why I bought the new machine. Sorry this is of no help but I hope someone out there can solve this for you.I will keep an eye on the post in the hope that one of the answers you get will enable me to revive my old machine.
