I have been having a problem where the Desktop Window Manager (on Windows 7) crashes randomly. Typically, there is no BSOD, but the entire computer locks up. On a couple occasions it has recovered and told me that Desktop Windows Manager crashed. Most of the time I don't want to wait so I hard reboot by removing power sources to the machine. When it crashes, I can move the mouse and click on things, but nothing happens (although I believe it is recorded, as the actions are performed on recovery). Also, I cannot bring up Task Manager during the crash.
I found the report in Windows Action Center from the most recent time it crashed and recovered:

I have been Googling this with no success so far. It seems to occur most often while running Chrome/YouTube, so I could just avoid that, but I'd like to understand why this is occurring.
BTW, I have 8GB of RAM, of which I only use 2-3GB.
EDIT: My computer is a laptop, the chip type is "Mobile Intel 965 Express Chipset Family". The adapter string is "Mobile Intel GMA X3100".
