I had a similar problem (Crashing @ 100% loaded) with this machine and its Intel 4600HD.
The driver your computer's manufacturer (or OEM) put in is most likely out of date, and the exe installer for the updated driver will probably not want to work because the OEMs tend to tweak the things, so the generic Intel driver will refuse to update over the OEM-modified version out of concern for the safety of your system's functionality.
First, you'll want to:
1. Make a system restore point; it's always a good idea to do this before messing with drivers.
2. Go to
https://downloadcenter.intel.com/ and find the Graphics Driver that matches the system you have.
3. Go to your OEM's website and see if they have the driver for your system.
4. Compare versions and updated dates.
If the OEM's version is actually up to date with the Intel one:
5a. Download and install the OEM driver.
Otherwise:
5b. Download the zip version of the updated driver at Intel's Download Center
6. Unzip the thing to a location you can easily locate.
7. Control Panel -> Hardware -> Device Manager
8. Under Display Adapters, right click the Intel(R) HD Graphics 4000 and choose Update.
9. "Browse my computer for software" then "Let me pick"
10. Select the Intel 4000 then click "Have Disk"
11. Navigate to the folder where you unzipped the Intel driver, then enter the Graphics folder.
12. Select the igdlh64.inf file there and open.
13. Continue from there and your computer should update the driver to the new version, uncaring about the generic vs. OEM issue.
It's what I had to do, and it worked.
