In device manager is a yellow mark on NVROFLASHDev and Parport. In the NVR0FLASHDev tab the device status; This device is not present, is not working properly, or does not have all its drivers installed. (Code 24). What is this and how to correct it? I'm also experiencing some nv4_disp BSOD errors during game play. Crysis and COD4. Usually the game/windows freezes and have to reboot.

Any help would be appreciated.

The NVR0FLSHDev is linked to ntune. Probably causing your grief with the BSODs as well. Uninstall ntune.
To do this apparently you need to  install ntune again and you can choose to uninstall at some point in the process.
Parport issue explained by MS.


Thanks for the answer. I have no NTune installed at the moment but still some remains in the program files folder under NVidia corporation. But I try to reinstall and then uninstall.


Tried NTune install and uninstall, but didn't help. Still have the yellow mark on NVR0FLASHDev in device manager. COD4 crashes almost immediately and after a while BSOD with nv4_disp.dll error. Processor Intel E8500. Also tried disabling NVR0... but didn't help either. Parport issue OK. Have the latest drivers and tried clean install, rolling backwards to older ones but didn't help. How do I get rid of this annoying mark in device manager. If it doesn't affect my PC then it's OK, but still like to solve it.

Thanks for info but the problem was faulty RAM. I changed spare RAM to line 2 instead of line 1 (can be also a faulty line in motherboard) and now its working fine. Suspected it was something else than driver issues. I been playing COD4 for 2 h and no freeze/BSOD.
