I have a Lenovo laptop (z60m). It has a Ricoh 4-1 Card Reader. It's always worked pretty great. The other day my computer started quickly making the "device detected" and "device removal sounds" constantly. It was like I was putting in and taking out an SD card over and over. Then it stopped. Suddenly my CPU was going really slowly. In Task Manager the System process (NOT System Idle Process) was running at 99%. I was quite confused. After doing some digging online I found out that this can be caused by a faulty driver. I opening up Process Explorer to see what was causing the System process to go nuts. It turns out it was a driver called "rimsptsk.sys." It's the Ricoh MS Driver. MS stands for Memorystick. I was able to pause the process in Process Explorer and my computer went back to normal. I realized the strange behavior of my card reader and the high CPU lag were connected. I went onto the Lenovo website and downloaded the driver package for the Ricoh 4-1 Memory Card Reader. I uninstalled the driver from Device Manager and then reinstalled from the Lenovo driver package. I restarted. At first it seemed like everything was okay, but then the same thing started to happen again. Since then I've tried many ways fixing the driver. I've updated from the device manager (said there was nothing to update). I've downloaded other driver packages for the Ricoh 4-1 Card Reader. Nothing works.
My question: Is there anyway to remove the drivers entirely and then reinstall them? If I uninstall the Ricoh 4-1 Card Reader from Device Manager and then restart, it just reappears after I log-in. I'm very confused. Right now I simply disable the process in Process Explorer and go about my business, but that stops my Card Reader from working. Help?
PS. There is a new drive (E:) in My Computer that wasn't there before called "MemoryStick." I think it appeared after my computer constantly made the "device detected" and "device removed" sounds. When I put an SD card into the Card Reader, it makes the "device removal" (instead of the "deviced detected") noise and the MemoryStick drive (E:) disappears from My Computer. When I remove the SD card, it comes back. It's like my Card Reader got confused and forgot how to work. Maybe a reformat is in order....
