My computer mysteriously stopped working yesterday when I installed a webcam. I installed the software, hooked the webcam with the computer and what happened that it asked me for reboot. I did so and now what I see is the main desktop but without any icons or stuff...I think it is the screen before the main desktop is loaded...

Anyone out there have any idea why is so? or what should I do to cure the error. The OS installed on the system was WIN XP...

Thanks in advance!
