About the Authors Jim Aspinwall writes to support his PC habit, and he conveys his experiences to others as author of IRQ, DMA, & I/O and as Computer Currents magazine's "Windows Advisor" columnist. He brings to this fifth edition of Troubleshooting Your PC Bible several years of experience with PC utility software, PC diagnostic software, telecommuter-networking technical support, and online support. He has worked for DiagSoft, Vertisoft, TuneUp.com, Quarterdeck, and various high-tech firms. A consummate tinkerer, Jim still finds a few moments away from the keyboard to spend at his workbench in a dusty mountaintop radio shack or on a cold steel tower to build and maintain amateur-radio repeater systems. Mike Todd founded the Internet Society Los Angeles Chapter, the Capital PC User Group in Washington, DC, the IBM Special Interest Group on CompuServe (also on The Source and on Unison), and has promoted the development of computer user groups around the world. Along with Professor Sumpei Cumon, Mike spoke in 1985 at the inauguration of the NEC PC Value Added Network, which was one of the first public networks established in Japan. . Before retiring from the U.S.Navy, Mike fostered the development of the Navy&s Microcomputer User Group and trained the people who manage public education in how to use their PCs at each of the regional offices of the U.S. Department of Education. Most recently, Mike, along with a few new friends, has founded the Internet Society Los Angeles Chapter (ISOC-LA). At one of the first ISOC-LA sponsored events, which provided a free clinic for anyone having problems with their computer, Mike even helped a few MAC users upgrade their computers so that they could connect to the Internet. Mike's interests include developing communities and commerce over the Web, information systems technology, health care administration, applications in business and government, programming, computer consulting, hiking, body surfing, bicycle riding, and travel.
