There could be several causes for this issue –
Major cause could be corrupt driver installation; but there is a good chance that it is the result of the last update of you ATI Graphic Adapter Driver. There are reports that AMDs Graphic Driver version 12.9 can be causing the crash when using it with explorer and various fdisplay configurations.
It's also been reported that you can correct the issue if you either downgrade the driver back to 12.8.
There is also reports that if you just replace atiumd64.dll (version 12.9) with atiumd64.dll (version 12.8) the proble will go away.

I hope this helps!!
To remove your current driver if the crashes are too frequent, boot win 7 in safe mode
You could be prompted for the administrator password or confirmation that you are allowed to make those kinds of changes;
Step 1:
Download the appropriate graphic card drivers from the manufacturer’s website (Version 12.8 and 12.9 )
http://support.amd.com/us/gpudownload/Pages/index.aspx
Step 2:
Explode the 12.8 driver so that you can get to file atiumd64.dll and save it somewhere you can get to it.
Step 3:
Remove your current install of the graphic adapter from the Device Manager by:
a) Right-click My Computer
b) Select Manage
c) click Device Manager
d) Locate Display Adapter
e) Right-click the device name
f) Select Uninstall Driver
Step 4:
Reboot
Step 5:
Install the ATI driver 12.9
Search for atiumd64.dll (the 12.9 version) and repalce it with the 12.8 version
