windows blue screen

Dear experts,
When I try to copy files from my system drive (c) ssd to a HDD my PC slows down - hangs and after a certain it crashes with a blue screen.
I also cannot synchronise my local FS (the folders I configured to be synched) with Wuala
Here are the sysdump detailed errors:

All the USB drivers are up to date - the problem started arising after the last huge MS patch day May 13th

Many thanks for your support

Do a system restore to before the patches were installed, or uninstall the patches manually one by one, until you found the one that causes the crash.

In addition to the above, the error implicates a driver. See this Microsoft Answer thread.

Try replacing / upgrading the video and network drivers.
Run memtest86 and test memory.
Also run System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down, start up and test.
