Under Applications and Sysytem look for yellow and red warnings and errors - right clcik on error and select properties and you will see the rogue program or hardware with error details under description.

yogi, did you install either daemon toos or alcohol :no:

 

[saumilsingh]

PnP BIOS Extension = DAEMON Tools
Plug and Play BIOS Extention = Alcohol

yeah dipdude recently installed the latest daemon tools i think the prob has started after installing daemon tools as u can c in this post had trouble while installing it http://www.techenclave.com/forums/daemon-tools-4-0-a-57535.html

ok, then in that case remove it this way

If you have DAEMON Tools program group present in Start Menu then run Uninstall shortcut from there and follow instructions.
If mentioned program group does not exist because setup is not complete (eg. due to crash) or you unchecked this option during setup (eg. for security reasons), then locate the folder where you installed DAEMON Tools and run uninst.exe in this folder manually.
If your setup is not complete and not all files were copied due to some crash (so that even uninst.exe is not present) or uninst.exe fails with some error message then just delete all files from this folder manually, remove System32\Drivers\dtscsi.sys file and reboot your system.
NOTE: DAEMON Tools V4 also uses SPTD (SCSI Pass Through Direct) driver to access cdroms and it is also automatically installed during DT setup. But SPTD is not removed during uninstallation because it may be used not only by DAEMON Tools but by other applications as well and its removal may disrupt these applications.Nevertheless, if you suppose your problems are SPTD releated you can remove it as specified in this thread

also do visit this thread, to get the solution to the error you had while installing

one more thing dont worry about the exclamation mark in device manager, pnp bios extension is for daemon tools & it just means it is not properly installed.
