Is it safe to delete nvraid.sys from Windows\Drivers? I am not using RAID in my system configuration at all - I have a single 1Tb SATA hard drive running Windows 7 32-bit Home Premium. The Event Log shows: Warning nvstor 129 reset to device, \Device\RaidPortØ, was issued This CONSISTENTLY coincided with a 20 second to 2 minute to TOTAL freeze. Occasionally the Event Log would also list the following: Warning Display 4101 Display driver nvlddmkm stopped responding and has successfully recovered After extensive research, I deleted nvraid.inf and nvraid.pnf from Windows\inf folder and rebooted my computer [at 3pm today]. Since then I have had zero freezes. But there is one disturbing occurrence, the Event Log now contains hundreds [1 every 30 seconds] of the following: Warning nvstor 129 reset to device, \Device\RaidPortØ, was issued Hence, the question: Is it safe to delete nvraid.sys? Thanks in advance, merlinx0057 PS: all drivers [for everything that I need & use!] are up to date by Windows Update standards & those of the individual manufacturers.
