The genuine jraid.sys file is a software component of JMicron JMB36X RAID Driver by JMicron Technology Corporation.
The “jraid.sys” driver used only in 64-bit Windows computers resides in “C:\Windows\System32\drivers” and can be started or stopped from the Control Panel “Services” applet. Stopping it is not recommended as it controls the JMB36X storage controller designed by JMicron Technology Corporation of Taiwan. JMicron, which has a large R&D facility in Irvine, CA, USA, designs storage device bridge and controller chips with RAID (Redundant Array of Independent Disks) capability. The version of “jraid.sys” must suit both the hardware and the OS, as the 2009 version in Windows 7 Pro 64-bit computers often causes driver power state failures upon upgrading to 64-bit Windows 10 Pro.

Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
