Question: Shirley asks, "My desktop computer was making a buzzing sound, and now won't power on. What could be wrong?"
Answer: Good question, Shirley. All computers nowadays use fans of some sort to keep cool. On a desktop computer, you'll find at least 2 fans, one on the processor, and the other in the power supply. You may also commonly find fans on the video card and the back of the computer's case. Any one of these can cause the computer to make a low buzzy/vibraty sound, which can get very loud. That happens because the bearings in the fan are wearing out. At some point, the system will become quiet again, but it will be because the fan has stopped altogether. If that happens, heat can, but may not, build up on the inside of the computer and damage other components. If you don't feel comfortable opening up the computer’s case, I'd suggest taking it to a shop you trust to have this checked, but if you'd like to know which fan is making the noise, open the computer and run it until the noise starts. Locate each of the fans and then use your finger to stop the fan by pressing on the center of the fan. When the noise stops, that's the one. Once it's been replaced, you're good to go. Now, if the fan in question is on the video card, then you may have to ultimately have a new video card because those fans are usually harder to find than a new video card.
Cool Site: YouthPastor.com: Have you seen YouthPastor.com? It's a site that has been around since 1997 and has been dedicated to giving youth pastors free youth ministry resources. Some of the resources they have available are a job center, free lessons, searchable directory of ministries, and game ideas, which is how I found the site. In the Job Center, churches can post their openings, and people looking for a position can post their resumes. They have 208 lessons arranged by category, and 336 games listed online. Both of these lists can be searched using their respective search functions. There's a topical index of Contemporary Christian Music so that youth workers can incorporate music into lesson topics. There's a recommended reading list that connects you to several books at Amazon.com, many of which are only a penny. The site also offers several other areas, go check it out. It's a really great place to start when looking to enhance your youth programs.
Cool Gadget: BioPrinting: This week we've got one of those hi-tech medical gadgets to talk about. We all know what a printer is. Well for prototyping things, there's a device called a 3D printer that can take a drawing file and turn it into a finished item. Now, researchers at Wake Forest University Institute for Regenerative Medicine have begun working to create artificial organs for transplant. This printer uses cells rather than plastic or some kind of foam to print, and I use that term loosely, organs. They have succeeded in printing tiny hearts that begun to beat when finished. They've also been able to create full-size versions of organs like bladders that are much less complicated. Just imagine being able to have a new organ printed from your own stem cells. No more anti-rejection drugs. It's years away, but an awesome technology.
It's All "Geek" To Me: Format: This week's term has one definition, but a lot of applications. Format. The word generally refers to the arrangement or layout of something for use. In computing, we're talking about things like the way a page is laid out for printing, or about the way data is arranged inside a file, or most commonly, about the way a disk is prepared for use. Formatting a disk is a process wherein data areas are set up, and a root directory structure is prepared, and other housekeeping tasks are performed. Normally though, the disk's data is not wiped off, so if you should happen to accidentally reformat a disk, you can usually recover all the data that used to be there.
