Common Errors in PC & There Solution

Common Errors in PC & There Solution

1. MONITOR LED IS BLINKINGCheck all the connections like Monitor Cable, Data cables,RAM, Display Card , CPU connections.

2. CONTINUOS THREE BEEPSProblem in RAM Connection.

3. THREE BEEPS ( 1 Long 2 Short)Problem in Display Card Connection

4. THREE LONG BEEPS PERIOD WISEProblem in BIOS or RAM (Basic Input Output System)

5. CONTINUOS NON-STOP BEEPINGKey Board Problem (I.e.; Some Key is pressed for Longer time)

6. FDD LED IS GLOWING CONTINUOSLYData cable to be connected properly (twisted cable).

7. NO DISPLAY ON THE SCREEN AT ALLHard Disk cable connected wrongly. Connect rightly seeing the Red mark (Faces power supply) and then Restart.

8. POWER LED IS OFFa. Check main power cordb. Check S.M.P.S.c. Check Mother Board connection

9. SHOWING CMOS ERRORReplace 3 Volt battery of Mother Board . Set Original Settings Manually.(Refer CMOS Setup chart)Enter your search termsSubmit search form

10. SHOWING FDD ERROR OR FLOPPY DRIVE IS NOT WORKING PROPERLYCheck Power cord of FDD , Data Cables , set CMOS & Finally the Check drive.

11. SHOWING HDD ERROR OR HARD DISK FAILUREa. Check Power Cordb. Check connection of HDDc. Check Data cabled. Check Hard Disk parameters in CMOS or Auto detecting Setting Partitions by Fdisk Command, then format it to set track 0. 12. MOTHER BOARD HANGS DUE TO UNSTABILIZED POWER SUPPLYa. Check S.M.P.Sb. RAM not functioning properly.c. Software problem (due to using pirated software)d. CPU fan not functioning properly.

13. DANCING SCREENa. Check Display card connectionb. Virus Problemc. Video Memory Problem

14. SHAKING SCREENa. Earthing problemb. Magnetic waves comes around

15. CPU CABINET SHOCKa. Check Earthingb. Check main power cord.

16. NON-SYSTEM DISK ERRORa. Floppy Drive having different disk (Non-Bootable Disk) OR CMOS Parameters for Hard Disk may not be set properly.b. Hard Disk Partitions may not be created. c. Hard Disk may not be formatted.

17. MISSING OPERATING SYSTEMThe System files missing namely Ie; command.com} - User File IO.SYS & MS_DOS.SYS } - Hidden Files. These above three files required for Start up of the system that can be transferred by using SYS C: Command OR While the time of formatting by using Format c:/u/s

18. MISSING COMMAND INTERPRETORMay the file Command.com is corrupted OR Infected by Virus OR Some one has Erased it.

19. SHOWING I/O ERRORa. The type of Hard Disk in CMOS may not be set properly.b. Operating system used for formatting is not valid

20. SHOWING DIVIDE OVER- FLOW MESSAGEa. May some Directories or Files crash with other files.b. Use CHKDSK/F or SCANDISK Command to correct it.

21. HARD DISK MAKING NOISE WHILE PROCESSINGa. Unstabilized power supply.b. Check for Loose Contact.c. Do not use Y Connectors for Hard Disk.d. It may crea

22. HARD DISK HANGS WHILE PROCESSINGCheck for Bad Sector by using CHKDSK or SCANDISK Command. If found format the Hard Disk and set Partition before that area.(This is the only procedure to use Hard Disk with Bad Sector) OR (To avoid Bad Sectors use Standard Power Supply)

23. HARD DISK NOT DETECTEDa. Check Power Connectorb. Check Data Cablesc. Check Jumpers

24. PARTITION NOT SHOWNOperating System where the Hard Disk formatted is not supported with present Mother Board. For Eg: Hard Disk formatted with Pentium System will hide their partitions for 486 System

25. MMX/DLL FILE MISSINGMay the above files may be corrupted due to power failure or Virus. Make available above files from other Computer. OR Reinstall Windows 98 Operating System. (This procedure will not make any effect on existing Data).

26. WINDOWS REGISTRY ERRORThis will happen due to sudden ON/OFF of the system. Final solution is to Reinstall Operating System

27. DISPLAY COLOUR DOES NOT MATCHa. Configure Display Card properly with their CD.b. The Standard setting for Windows is set it to 800x600 for better performance.
