TROUBLESHOOTING

Basic Troubleshooting Technique:1. Problem Identification2. Zero in on the cause3. Repair or Replace

Meke the planFollow the process from beginning to endConduct the repair or replace

4. Conform the result5. Document the document

Problem 1 No Display

Cause 1 Loose connection of monitor cable with display card.Solution: Connect properly

Cause 2 Display card not fixed properlySolution: fox properly

Cause 3 RAM installed improper/ loose.Cause 4 processor not fixed properlyCause 5 failure of display cardCause 6 failures of SMPS

Solution: check output voltageCause 7 defective RAMCause 8 defective MotherboardCause 9 check CMOS batteryCause 10 monitor resolution is improper

Solution: set safe mode (enable VGA) (normal size (600*800))

Problem 2 Not clear display (only 16 colors)

Cause 1 improper display driver Solution: Install proper driver.

Problem 3 Continuous beep comes when switch on the system but display doesntcome.

Cause 1 RAM not installed properlyCause 2 Memory slot damaged

Solution: Change motherboard.Cause 3 Display card not installed properly.Cause 4 defective display cards.Cause 5 Keyboard failure or any key pressed

Problem 4 Floppy LED glows continuously

Cause 1 Reverse data cable

Problem 5 Floppy drive does not read

Cause 1 Disk may be damagedCause 2 Wrong CMOS setting about floppy disk drive type.Cause 3 Head may be dirty (Use cleaner)

Problem 6 Hard disk failed

Cause 1 Power and data cable not connected properlyCause 2 Power and data cable may be damagedCause 3 Wrong CMOS settingCause 4 wrong jumpers settingCause 5 Hardware may be damaged

Problem 7 Memory Test Failed

Cause 1 Improper memory chip installedCause 2 Mismatches memory chips is installedCause 3 Memory slot damagedCause 4 RAM is fault

Problem 8 Mismatched processor speed

Cause 1 Improper selection in CMOS settingCause 2 Improper jumper setting (Older)Cause 3 Motherboard does not support

Problem 9 automatically resisted the system

Cause 1 Defective RAMS (Replace after check)Cause 2 Hard disk is full of dataCause 3 Defective motherboardCause 4 Due to virus attack

Problem 10 shows lower memory RAM slot

Cause 1 Any gold connection of RAM is damagedCause 2 Memory slot may be damaged

Problem 11 System hangs frequently

Cause 1 CPU cooling system failedCause 2 RAM defective or low memoryCause 3 Motherboard defectiveCause 4 Hard disk is full of data (For virtual memory)Cause 5 Improper setting of peripherals is CMOSCause 6 Virus attacked the programCause 7 Bad Sector in the hard disk Cause 8 Monitor resolution is high

STEPS OF CHECKING TO TROUBLESHOOTS

Find through beep and error code. Check power source. Check power cable connections. Check ports of connections. Check cable in the system CMOS battery. Check RAM, Display Card and for proper installations. Be sure motherboard is not touch to its chassis. Sure the problem and find faulty hardware.

If problem in software or operating system then BOOT with floppy or CD ROMsupported transfer system file to system drive or hard disk. If problem is not solve

by this process, the backup necessary file to another drive in DOS mode theformat C:\ drive and install fresh copy of operating system. If any device driver ishaving problem see in device manager. There will yellow exclamatory sign (!)there and right clicks on it and uninstall the device. If again seems for thehardware then installed proper driver by CD ROM or floppy.

PROBLEM IN OPERATING SYSTEM

GENERAL OPERATON ERROR

Windows protection faultGeneral protection faultIllegal operation

It is caused by memory division problem or if any program enters into another programs memory area t hen this types of error occurred.This type of problem can be solving by rebooting, if not then check memory (RAM)module.

Fatal exception error or error exceptionIt is caused by poor CPU cooling system or defective memory module (RAM).


5/5



Registry problemThis type of error may caused by corrupted operating system or often caused byhardware problem (Hard disk or motherboard or processor).

Seems press F1 when switch the system It is caused by:-

1. Due to improper CMOS setting.2. CMOS battery low.3. CMOS chip defective.

Windows protection error It is caused by:-

1. Conflict between peripherals.2. Defective memory module (RAM).3. Defective operating system or software program.4. Defective motherboard, CPU etc.

Error on menu bar/ saving (Can not save a file during work or hidden menu or bar.)It is Caused by:-

1. Virus attacked.2. Improper CMOS setting (see BIOS Hard disk read/ write.)3. CMOS battery low.4. Jumper setting is improper.
