I used process explorer to find that System was using 99 percent cpu (Not system idle process) and then right clicked and went to properties to find two threads were split 50/50 in memory usage. One was the windows kernel file, and the other was something called rimspe64.sys+08.... some jargon. That is to my understanding a normal windows driver found in system32/drivers. By clicking on the properties of that thread It seemed to be associated with a device that came up in my device manager "Ricoh memory stick disk device". I have no idea what that is but I attempted to disable and uninstall it. Upon restart it was still there. (under disk drives in device manager). Also, during this whole time my pc was randomly making the usb device disconnet/reconnect sounds.
So in safe mode, I just moved rimspe64.sys from the drivers folder, to my desktop. Also, I turned off usb and usb sleep in charge in my boot menu. There was no immediate effect but I restarted, am now in normal mode and the pc is functioning properly. I am assuming this cannot be a permnanent fix as other things need to use that driver and was wondering how to move forward.
The Ricoh memory stick disk device no longer shows up under disk drives in device manager, I am afraid to move the .sys file back, and was just wondering if anyone knew how i should proceed or what tools I should run/ actions I should take?
Thanks for any help and I was unsure where to post this, I hope this was the correct forum.
