I've got a single user that has develoiped repeated Unhandled Exception 18F7FC errors on his PC. The only thing that changed was a repair install of Office 2010. Seems to have started since then.
I did several searches and did some standard fixes:
Repair Install of AutoCAD LT 2008
Updated Video Drivers
Nothing has fixed the problem. He is still able to work but I've been tasked with stopping this problem.
He is on WIndows 7 64BIT
Many others are on the same setup but he is the only one with the problem.
First of all, run a disk scanner over the drive to make sure it's not a hardware problem.
Then run a registry scanner over the registry before you try a repair of Win 7 as the registry may have been corrupted.
With the .net files, did you remove them totally and then re-install them? A repair of them will not work most of the time.
Finally if all of those don't work, you may have to try un-installing ACAD and re-installing it.
