Q I'm looking to set up an live Internet streaming video and audio show. To produce it, I need to have several video-audio streams from remote locations running on my PC at the same time. What kind of a laptop should I purchase? What else do I need to think about?
RYAN ALPERSTEIN, St. Louis Park
A You can be your own broadcaster, but it's not cheap.
The computer is actually the least of your concerns; an off-the-shelf Windows 7 PC will do.
Likewise, the set-up isn't difficult. What you describe is really nothing more than a building security system in which the video from each camera appears in a different window on the PC screen.
But it gets pricey. Axis Communications bundles the video software with four cameras (see tinyurl.com/d48fk9c) for about $800 (see specific system requirements at tinyurl.com/cm7sb3u.) Or you could get just NCH Software's streaming program for $99 (see tinyurl.com/368qut.)
If you have your own website, you can do live streaming through an online provider such as StreamingVideoProvider (see tinyurl.com/yzntq54) for $77 a month. Livestream (see tinyurl.com/c7jbak2) costs $45 a month.).
Q I have a Compaq laptop that warns me I'm running out of space on my "D drive." What can I do?
ROBERT MIGGINS, Tucson, Ariz.
A The D drive isn't really a separate drive, but rather a small partitioned area on your hard drive, or C drive. The D drive area is designed to hold only fix-it software for the PC, and has little extra space. Unfortunately, automatic data backup software will sometimes copy information into the D drive space, filling it up and generating the warnings you've seen.
You can get rid of the warnings by clearing unnecessary data from the D drive partitioned space. To do it safely, see tinyurl.com/csmpjz5.
Q I need to transfer about 25 complex Excel spreadsheets from my 64-bit Windows Vista PC to my new Windows 7 PC. In the past, I've had trouble transferring files of this type between computers because parts of the spreadsheets become misaligned and I end up having to redo them. Is there an easy way to make the transfer?
THOMAS LOTZER, Eden Prairie
A Make a direct connection between the two PCs with a USB cable designed specifically for their two operating systems (see tinyurl.com/35eddhq). You'll also need Microsoft's free "Windows Easy Transfer" software; the 64-bit Windows version for your PC is available at tinyurl.com/cb426ge.
