this is a free driver solutions this will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point click no to both of these then continue updating each driver free then restart once all of the drivers have been updated Some webcams and programs require additional software, although that should be installed with the webcam if things are right. But is does not harm to check if your Java, Flash and Quicktime software are installed and up to date. But certainly check your DirectX software, since all video applications, including webcams, use DirectX for video processing. Try downloading the latest DirectX version and install it (Windows XP: DirectX 9.0c - Windows Vista: DirectX 10). http://windows.microsoft.com/en-US/windows7/Which-version-of-DirectX-is-on-your-computer hope this helps
Possible that PC is hanging up as there is fault on the OS (operating system) or a virus in the OS. Also it is possible that the backup battery (CMOS) has low voltage or the memory card is a suspect. In this case you need to check the voltage and also try and swap a memory card. Sometimes the memory card connections can be faulty either on the card or on the slot. Cleaning the slot and card must be done before you try a replacement. If the PC boots and fails then the hard disc can have bad sectors or is corrupt. However if there is no result the motherboard also can be suspected. In this case you might need the help of proper tools and equipment support to do a chip level service.
