Friends I was home and my Home PC has Consistent motherboard and 256 MB RAM, Kids used to learn by this computer. It has Pentium 4 processor. I played a video it was stucked, only audio sound was coming. then I checked from the device manager and found that it was missing VGA Controller driver and because of that it was not able to play videos . Although RAM is also less but yet I thought to install VGA Controller for this Consistent motherborad Pentium 4 with With Windows xp sp3.
