Computers today will hold a lot of information but sometimes we put so much information on them that they fill up and bog down so that when we open a program it may take a while, so we click again and again. Then we have about three running at the bottom of the screen and that many running in the background using up your computers resources. To resolve this problem make sure you give each program enough time to open and then if you open the program more than once, close it. This can freeze your computer up.
Prevention is the best policy. One way to not lose files is to save often. My policy would be if document I was working on was something I did not want to retype, make a backup. Save it a disk, hard drive and network (G drive), all three or at the least two of them. When typing a document I save after a couple of paragraphs.
Always remember which program you were working in.
I lost my file/document, always remember which program you were working in, that way you can search a file with that extension. For example if I were looking for Office Word file I could search for a file with the doc file extension and use the * as wild card. (*.doc). Click on Start-Find-Files. Type *.doc and that will pull up all files with a doc extension. Or if you could not remember what it was named you could search by date modified under the Find feature and find all files modified or created on a certain date. Contact your STC if these steps do not work.
Occasionally the screen is not centered on your monitor. Each monitor has settings that allow the user to adjust the horizontal and vertical placement of the desktop on the monitor display. Generally these adjustments are made by using buttons on the lower edge of the monitor. These buttons are sometimes clearly labeled and other times just marked by obscure symbols. Using these buttons you can change the horizontal and vertical placement of your monitor to center it on the screen.
The first thing to check is that your speaker wires are plugged into the proper port on the back of your computer. You should see a left speaker wire and a right speaker wire, and they might be connected together into one plug. Make certain that you have placed this plug into the port marked with the speaker symbol. Often the microphone port is located right next to the speaker port, and it is easy to get them confused. If you have checked that the speaker cable is plugged into the back of the computer tightly, then verify that you have power going to your speakers and that the speakers are turned on. Some speaker sets have separate power supplies, while others draw their power from the computer. If the speakers are turned on, turn the volume all the way up so you will know when the sound starts working. If there is a little speaker symbol on the Taskbar near your clock, double-click on that symbol and make sure that the volume control is set high enough and that the "Mute All" or "Mute" is not checked. If these are checked, it will turn the sound off on your system, even if the speakers and other equipment are working just fine.
If your sound is from an intelligent classroom speaker with a projector, make sure you do not have other speakers or headphones hooked up at the same time.
Non-System Disk Error This most often occurs when you boot your computer up and a floppy disk was left in the floppy drive. Just pop out the floppy disk. This message could also occur when you have no operating system or the computer is experiencing hard drive failure.
Unplug the projector from its power source. Remove the filter and clean it. Reinstall filter and plug in the projector. If projector and light does not come on, the bulb may need replacing. Contact your STC.
