Iastor.sys causing crashes?


I have an HP DV6 6100. At least once daily (sometimes more), the computer will spontaneously restart -- it will just straight up go blank screen and reboot. I cannot pin it down to any cause in particular.

Using a program called WHOCRASHED, it gave me the following analysis... Anyone have any ideas on how to fix this?

What is the version of Intel® Rapid Storage Technology you are using?

For your system the latest version is https://downloadcenter.intel.com/download/23496/Intel-Rapid-Storage-Technology-Intel-RST-RAID-Driver 12.9; however, it was not intended to work with Windows* 10, so it may or may not work properly.
