Basic Computer Troubleshooting Tips

Computer troubleshooting
Basic Computer Troubleshooting Tips :
1. Check all connections
  • Are the power cords plugged in? If using a power cord, does it work with other electrical items?
  • Is the monitor cord to the PC connected?
  • Are keyboard and mouse cables fastened securely?
  • Is the network cable connected to computer and hub or wall connection? Is there a green link light on?
2. Turn computer off, wait 30 seconds and turn on again.

3. Narrow down problem
  • Have you added new software recently? Could impact other functions.
  • Is it a hardware problem? (monitor, keyboard, mouse, printer); try each component with another computer to see, if they work.
  • A keyboard error could be a loose connection or a stuck key. Check cable connections and run hand over the entire keyboard. Reboot computer. PC's have batteries that have a life, of about 3 years. If computer keeps asking what time it is, you need to replace battery. Can be found on the motherboard. Cost about $10 at Radio Shack, etc.
4. Have, you deleted, moved, or renamed files recently?

5. Has computer been moved (even a few inches)? - Check connections.

6. When you turn on computer, listen for beeps - one is very good, two to four beeps is usually a memory problem. More than four beeps can be a motherboard problem. (# of beeps also depends on which BIOS system is used).

7. Is the ‘num lock key’ on for using number keys at right of keyboard?


8. If your computer continually beeps .at you it could be, frozen and must be rebooted or shutdown. Try Ctrl, Alt, Delete at the same time. As a last resort, turn off power and wait 30 seconds to turn on. Win95 systems will prompt you to do a scandisk check - go ahead with this.

9. Mouse isn't working - try cleaning the ball. Sometimes the driver for the mouse will be missing. Copy mouse files from another computer and copy to problem machine. Most of the time there is no software to load for the mouse – just plug in and use. Mice do wear out, so check with other machines.

10. Monitor problems --- screen arrangement looks weird? - There are adjustments for vertical, horizontal, etc., on most monitors.

11. Printers used with Win95 systems have a troubleshooting guide built in by double clicking on My Computer and opening Printers. Choose the printer and use the Help files. Is the printer clean? Does it need a new cartridge? Try turning off and on again. Make sure you are choosing the correct printer in Print Setup. Are connections secured? 12. If you get a memory error, you either need to delete unused files and programs or buy more memory.

13. How much memory do I have? Type in mem at the DOS Prompt (C:/) on 3.1 systems. In Win95, open My Computer, right click on C: and choose properties. On both systems watch the scrolling numbers in the upper left corner when you turn on the computer.

14. Need a formatted disk to save on? With 3.1 system - at C:\ type, a:format or use, the, Main Menu, File, Manager, Diskettes. In Win95, use My Computer and right click on A: drive and choose Format. There are two capacities to choose from - 720 and 1.44. Use 1.44 for HD (High Density) and 720 for DD (Double Density). Disks must be formatted to save files. Transfer files after a year of heavy use to another diskette. Floppy disks do wear out and you can lose all your files.

15. You may want to make a copy of a diskette (for example – Integrade before you turn it in to the SIMS operator). In Win95, open up My Computer, put original floppy in the disk drive and click once to highlight. Choose the File Menu and select Copy Disk. Follow onscreen instructions. To use DOS to make a copy of a floppy disk, click Start, Run and type in: DISKCOPY A: A: and follow the instructions on the screen.

16. Computer will not boot or reboot with a diskette in A: drive unless it is a system disk. System disk can be used to boot a system that cannot boot on its own. Should keep a system disk for each system in use.

17. On Win95 systems, if a blue screen with writing appears, choose Exit without Saving. The computer should continue on to the desktop. 18. Is my hard drive full? Open My Computer, and choose File Menu, Properties. Sometimes, you will have two hard drives. Is one full and the other almost empty? May need to move files to the other hard drive. Contact your school technology trainer for assistance.

19. Once you have tried all the basis options of troubleshooting, maybe you have been able to either fix your own problem or narrowed it down. Contact the school technology trainer or TUG person for additional help. If they need assistance, they will complete a work order for your computer to be serviced by a system technician. So if you need extend your taskbar to across multiple monitors read Expand The Taskbar.

4 langkah untuk membersihkan komputer dari virus

Setelah virus pada komputer Anda dapat menyebabkan komputer Anda untuk memperlambat, memasang iklan dan mengintai hati-hati, atau membiarkan hacker ke dalam komputer untuk mencuri informasi Anda. Mengetahui bagaimana untuk membersihkan Anda terinfeksi virus komputer adalah mudah. Berikut ini adalah beberapa tips untuk menunjukkan bagaimana Anda.

Segera setelah anda berpikir komputer Anda mungkin terinfeksi Anda harus putuskan komputer anda dari Internet dan apapun jaringan Anda mungkin pada komputer. Ini adalah untuk memastikan bahwa virus tidak menyebar ke komputer lain.

Jika Anda memiliki anti-virus program terinstall pastikan sudah diperbarui pertama kemudian menjalankan penuh sistem pencarian. Anti-virus tidak dapat mendeteksi virus jika program ini tidak diperbarui.

Beberapa program anti-virus akan mendeteksi virus, tetapi tidak akan mampu untuk menghapusnya. Jika ini kasusnya, anda dapat mendapatkan program yang berbeda dengan mendownload dari komputer yang tidak terinfeksi atau anda dapat pergi ke toko komputer lokal dan mendapatkan satu ada yang berbeda.

Sebagian besar anti-virus program akan meminta Anda untuk me-restart komputer Anda setelah selesai scanning. Setelah Anda restart komputer Anda menjalankan scan lain untuk memastikan bahwa virus hilang. Bila Anda me-restart komputer pastikan bahwa itu masih terputus dari Internet dan jaringan lainnya. Setelah Anda yakin bahwa virus hilang, kembali komputer.

Software Piracy

Software piracy is the unauthorized copying of software. Most retail programs are licensed for use at just one computer site or for use by only one user at any time. By buying the software, you become a licensed user rather than an owner. You are allowed to make copies of the program for backup purposes, but it is against the law to give copies to friends and colleagues.

Software piracy is all but impossible to stop, although software companies are launching more and more lawsuits against major infractors. Originally, software companies tried to stop software piracy by copy-protecting their software.

This strategy failed, however, because it was inconvenient for users and was not 100 percent foolproof. Most software now requires some sort of registration, which may discourage would-be pirates, but doesn’t really stop software piracy.

SCSI (Small Computer System Interface)

It is the acronym for small computer system interface. Pronounce it skuzzy. SCSI is a parallel interface standard used by Apple Macintosh computers, PCs, and many UNIX systems for attaching peripheral devices to computers. Nearly all Apple Macintosh computers, excluding only the earliest Macs and the recent iMac, come with a SCSI port for attaching devices such as disk drives and printers.

SCSI interfaces provide for faster data transmission rates (up to 80 megabytes per second) than standard serial and parallel ports. In addition, you can attach many devices to a single SCSI port, so that SCSI is really an I/O bus rather than simply an interface. Although SCSI is an ANSI standard, there are many variations of it, so two SCSI interfaces may be incompatible. For example, SCSI supports several types of connectors.

While SCSI has been the standard interface for Macintoshes, the iMac comes with IDE, a less expensive interface, in which the controller is integrated into the disk or CD-ROM drive. Other interfaces supported by PCs include enhanced IDE and ESDI for mass storage devices and Centronics for printers. You can, however, attach SCSI devices to a PC by inserting a SCSI board in one of the expansion slots. Many high-end new PCs come with SCSI built in. Note, however, that the lack of a single SCSI standard means that some devices may not work with some SCSI boards.

CD-RW (Compact Disk – ReWritable) disk

It is short for CD-ReWritable disk, a type of CD disk that enables you to write onto it in multiple sessions. One of the problems with CD-R disks is that you can only write to them once. With CD-RW drives and disks, you can treat the optical disk just like a floppy or hard disk, writing data onto it multiple times.

The first CD-RW drives became available in mid-1997. They can read CD-ROMs and can write onto today’s CD-R disks, but they cannot write on normal CD-ROMs. This means that disks created with a CD-RW drive can only be read by a CD-RW drive.

However, a new standard called MultiRead, developed jointly by Philips Electronics and Hewlett-Packard, will enable CD-ROM players to read disks create by CD-RW drives. Many experts believe that CD-RW disks will be a popular storage medium until DVD devices become widely available.

Warm Boot

Warm boot refers to restarting a computer that is already turned on via the operating
system. Restarting it returns the computer to its initial state. A warm boot is sometimes necessary when a program encounters an error from which it cannot recover.

On PCs, you can perform a warm boot by pressing the Control, Alt, and Delete keys simultaneously. On Macs, you can perform a warm boot by pressing the Restart button.

It is also called a soft boot. Contrast with cold boot, turning a computer on from an off position.
