This week Adam Walton turns his attention to the recent Game Developers' Conference in San Francisco, our PC Doctor answers more home computer problems and we hear about the digital information explosion that we are all part of.

Game on for the future

The recent Game Developers' Conference in San Francisco brought together many of the big thinkers behind the video game industry. Shigeru Miyamoto of Nintendo and Peter Molyneux of Lionhead, two highly regarded game developers gave their visions of where gaming is heading, including injecting more emotion into games and broadening the appeal of games to bring in new players. Darren Waters, technology editor of BBC News website discusses the conference with Adam.

Information Explosion

Last year we generated 161 billion gigabytes of information. This mind boggling figure is growing annually as we increasingly turn to digital TV, digital photographs, web content and digital phone communication. Richard Wray, communications editor at The Guardian discusses where this mountain of data is leading us.

Funeral on the web

An enterprising funeral director now offers family and friends of the deceased, wherever they are in the world, the chance to watch a funeral on the web. The system is password protected and those who can watch are invited by the family of the deceased. Jim Clarke of S.Clarke and Sons in Northern Ireland explains how the web funeral service works.

The Ultimate Deep Clean! (but approach with caution)

One for the real techies and not for the unwary. Probably best to take your PC to a competent PC Engineer or Technician for this step!

Backup your important documents and files to external media and then format your hard drive and reinstall Windows from original media.
Reinstall useful applications and data. This gives you a really clean PC with no extraneous junk or rubbish to clutter things up and should also boost performance. But, we stres this is only for advanced users.
