I am running Windows XP Pro, when I start up, after the windows loading screen disappears I get the following message "userinit.exe - Application Error The application failed to initialize properly (0xc0000005). Click on ok to terminate the application." If I push ok, the same message appears again. Click ok again and my desktop background appears, but with no icons or start menu (no taskbar at all). I have already run Uniblue Registry Booster 2 and Norton 360 v2 - lots of stuff found and quarantined or deleted. Problem still exists. I've also run Hijkackthis and saved a log of the scan - see attached. I am able to run programs though ctrl alt delete Task Manager and connect to the interenet with no problems.
What was I doing when the first error message came up?: The problem occured when I inserted a USB drive, transfered some ASUS utility file, which were downloaded from the ASUS website and then tried to open the "add/remove programs' icon in the control panel. The above error message came up, I rebooted to find the above situation.
Tried and tested: Apart from running scans I have also tried to restart in safe mode and 'last working config' to no avail.
