VirtualBox.exe crashes after 10/20 min (only once) with error "The instruction at 0xef4bf61 referenced memory at 0x0000001c. The memory couldn't be read" "

I have a Windows 7 OS 64bit and I run a VirtualBox with Ubuntu 14.04. My machine has Intel Core i-73612-QM CPU@2.10 GHz with 8GB RAM. I allocate 5GB of memory and I use 2 monitors and 64MB for my VB. Every time I run the VB for the first time after I start my laptop from being switched off or hibernated, the VB works fine for 10/20 mins and then it crashes with the following error message: "The instruction at 0xef4bf61 referenced memory at 0x0000001c. The memory couldn't be read" After that I restart the VB whose status is reported as "Aborted" and everything works fine and it doesn't crash anymore. Any help/idea will be very much appreciated.

Many thanks, Alessio

Try to upgrade your Intel video drivers.

Please reopen if still relevant with a recent VirtualBox release.
