Use the diagnostic software on your computer. Try to find out the conditions under which the malfunction occurs. Try also to isolate where the problem is occurring. Is it with a certain software program or with your hardware? If the problem is with software, you should probably talk to your software dealer. If the problem is with the hardware, try to narrow down the source of the problem. Is it your disks or disk drives? Keyboard? Printer? Screen? If some messages appear on the screen, refer to your MS-DOS manual for an explanation of the message. You may want to write down the message or print it out with the + key combination. Problems (except blackouts) can be avoided if you run your system on a dedicated electrical line. That is, ensure that your computer and peripheral electric cords are not shared by other appliances such as a refrigerator or air conditioner. Also, it is highly advisable to purchase a surge suppressor. This is a set of electric sockets enclosed in a single housing. A surge suppressor prevents sudden pulses of high electric power (spikes) from damaging the computer. This appliance is inexpensive and can be purchased at any computer or electronic hardware store. Other items worth checking: Are you using a startup disk? Is your disk formatted? Is the system configuration correct? Are all the external and internal connectors are connected well? Make sure that you are running software compatible with your display port, because some software programs can only run in the MGA display mode. Is the power fuse burned out? If you have gone through the above checklist and your system still does not function properly, check the following pages. The following instructions will help you solve some common problems. However, you should be aware that other problems might stem from system software, applications or other peripherals. 6 Chapter 5: Troubleshooting
