Have several critical issues with the Intel HD4600 Graphics Drivers including the latest 15.36.7.3960.
System Details: Sager NP2670, Intel 4th Gen i7 2.8Ghz 4810MQ, 16GB RAM, Samsung Evo 256GB SSD, Win 8.1 Pro 64 bit, latest updates/BIOS/drivers installed.
1. System crashes on resume from sleep.
2. USB ports remain powered during sleep.
3. Video stutters intermittently while playing, while CPU, GPU, and RAM usage remain highly underutilized and loading/buffering is complete.
On crash in resuming from sleep, Event Viewer provides the following:
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

These issues are isolated to the graphics driver, as they do not occur in Safe Mode, or with the default basic VGA adapter driver in Windows. They are also present in previous versions of the driver.
Have tried all manner of uninstalling all graphics drivers, in safe mode, rebooting after each change, and cleanly re-installing different versions of the driver, to no avail.
