There is no harm in the computer.
1. The computer is used for too long, let the computer rest. Break it
2, there is too much dust inside the fan, you can go to the computer shop to remove dust
It should be the sound of hard disk work
Anything in the computer is definitely not normal. You have to determine what abnormal sound is emitted from the accessories, so that you can analyze the specific problem. If you don't understand it, it is best to find someone who will help you to look at it.
Is the sound of hard disk read
First determine the source of the sound, then find the cause to solve the problem based on its source.
If the power is enough, it will have no effect, as long as you can bear it.
Some of the hard drives are radiator fans.
It should not be the reason for the fans. Not a CD-ROM drive, because your CD-ROM drive is not enabled, it is estimated that your hard drive has bad sectors: Give you the following article to see, it will help you, don't be too long: The hard disk can be used for a long time, there may be various problems. The hard drive "bad track" is the most common problem. In addition to the quality of the hard disk and the cause of aging, the hard disk is mainly due to the fact that it is not suitable for the hard disk in normal use. For example, the memory is too small, so that the application software frequently accesses the hard disk, the hard disk is excessively defragmented frequently, and the overclocking is inappropriate. Poor quality, high temperature, poor dustproof, vibration, etc. Hard disk bad sectors are divided into logical bad sectors and physical bad sectors. The former is soft bad sectors, usually caused by improper software operation or improper use, and can be repaired by software. The latter is a real physical bad track, which indicates your hard disk. Physical damage is caused on the track and can only be resolved by changing the usage of the hard disk partition or sector. If your hard disk has the following symptoms, you should pay attention to whether the hard disk has bad sectors:
(1) When reading a file or running a program, the hard disk repeatedly reads the disk and Error, prompting file corruption and other information, or it takes a long time to succeed; sometimes even a blue screen appears; (2) The sound of the hard disk suddenly changes from the original normal friction sound to a strange sound; (3) In the case of eliminating the virus infection The system cannot be started normally, and the message “Sector not found” or “General error in reading drive C” appears. (4) When the FORMAT hard disk is stopped, the progress is stopped, and the final error is reported, and cannot be completed; (5) The secondary system will automatically run Scandisk to scan the disk error; (6) When FDISK is executed on the hard disk, it will go back and forth repeatedly to a certain progress; (7) The system cannot be booted through the hard disk during startup, and can be transferred to the hard disk after booting with the floppy disk. Character, but can not enter, using the SYS command to transfer the system can not be successful. This situation is most likely caused by a problem with the boot sector of the hard disk. If the above error occurs, you need to be extra careful, which means that your hard drive has bad sectors! Repair of hard disk bad sectors 1. Fix logical bad sectors Start with the easiest way. With the disk scan tool under Windows, right-click the drive letter in the Explorer and select it in the pop-up drive properties window (Figure 1) (Figure) "Tools → Start Check" to set the scan type. Make a full scan and choose to fix the error automatically, then click Start. The scan time will vary depending on the disk capacity and scan options (Figure 2) (Figure). If the logical bad track exists in the system area and it can't start normally, we can use the Windows 98/Me boot disk, type: Scandisk drive letter at the DOS prompt, press Enter, once the bad track is found, the program will prompt you whether you want Fix it, choose Yes to start repairing, and many problems that cannot be started properly due to logical bad sectors in the system area can generally be solved by this method. Because Windows 98/Me largely repairs logical bad sectors to a large extent, and cannot automatically repair physical bad sectors, in fact, the first method often does not work. What should we do if we encounter physical bad sectors?
2. Scanning physical bad sectors with Scandisk can't do anything for the physical bad track Scandisk. It can only mark it as bad sectors and no longer read and write this area. Physical bad sectors have "infection" "Sexuality" spreads to the periphery, causing data stored near bad sectors to be at risk. When using Scandisk, stop when the bad track is found. Pay attention to the value when the Scandisk is stopped, such as 22%. Assume that the total capacity of the hard disk is 2GB, 2GB×22%=0.44GB, and the starting position of the hard disk is about 440MB. Because the bad sectors of the hard disk are easy to spread to the periphery, you must leave enough buffer to set the capacity of the first partition of the hard disk to 400MB. The remaining 1.6GB is divided into 8 areas according to 200MB. Use Scandisk to check all partitions. Partitions that cannot be detected by Scandisk are deleted or hidden to ensure that the system no longer reads or writes to these areas. The remaining adjacent partitions can be combined and used. Partitioning, hiding, deleting, merging, etc. can be performed using a graphical interface such as PartitionMagic or DiskMan.
3. Use software to hide physical bad sectors. Use PartitionMagic5.0/6.0 to process hard disks. PartitionMagic can repartition the hard disk without changing the data, dynamically change the partition size, change the file format of the partition, hide or display the existing partition, and so on. Copy the DOS version of PartitionMagic5.0/6.0 to a floppy disk, boot the system with the Windows 98/Me boot disk, and run PQMAGIC.EXE on the floppy disk. Then scan the hard disk, you can directly use the "check" command under the Operations menu in PartitionMagic. After marking the bad cluster, you can try to re-test it by selecting "Advanced/badSector Retest" under the Operations menu; After dividing the bad cluster into one (or several) zones, hide the partitions with bad sectors through the HidePartition menu item to avoid misoperation in Windows 98/Me. Special note: If you do not format the partition to hide the bad sectors directly, then the subsequent partitions of the partition will cause some of the drive-related programs to not run correctly due to changes in the drive letter. The solution is to use the DriveMapper menu item under the Tools menu. It will automatically collect shortcuts and related information in the registry, and immediately update the drive letter parameters in the application to ensure the normal operation of the program. 4. Repair the hard sector 0 sector bad sectors For the hard disk 0 sector damage, although it is more difficult, but it is not hopeless, we introduce two methods here. The first method: We borrowed the DiskMan software to fix it. The specific method is as follows: 1 Run DiskMan in pure DOS mode, select the drive symbol in the “Hard Disk” menu, then the partition format of the hard disk displayed in the main interface is FAT32, starting cylinder 0, starting head 1, total capacity 2GB; 2 then enter "Tools → Parameter Modification" (or press F11), in the pop-up modified partition dialog box, change the value of the starting cylinder to "0" to "1"; 3 press OK to return to the DM main The interface and press F8 to save the modified result. After the modification, you need to reformat the hard disk. The second method: We use the DE tool in the familiar Pctools9.0 software. The specific methods are as follows: 1 Start with Windows 98/Me boot disk, run DE.EXE under Pctools9.0 directory, first enter the Options menu, select Configuration, press the space to remove the hook in front of Read Only. Tab key switch), save and exit; 2 then select Drive in the main menu Select; 3 Enter Physical (physical) in the Drive type item, press space to select, then press Tall Switch to the Drives item, select Hard disk, then choose OK to enter; 4 then return to the main menu, open the Select menu, then the Partition Table will appear, select and enter, then the hard disk partition table appears Information; 5 If the hard disk has two partitions, the l partition is the C drive, the partition starts from the 0 cylinder of the hard disk, then change the 0 of the Beginning Cylinder of the 1 partition to 1 6 Save and exit; 7 restart, press the Delete key to enter the COMS settings, select "IDE AUTO DETECT", you can see that CYLS is reduced by 1, save and exit, re-partition, format, and you're done. Tip: Back up the important data on the hard disk before modification, and Pctools9.0 can not run on the FAT32 partitioned hard disk and Windows, but can run on the FAT16 hard disk. After repairing, you must re-detect the hard disk in CMOS, and then partition and format, because the partition table information will be written to 1 sector (now as 0 sector) only after formatting the hard disk. 5. Low-level formatting to repair bad sectors All of the above methods can't work, and you don't want to be forced to use the low-level format to deal with hard disk failures. However, low-level formatting will re-calculate tracks and sectors, label address information, and set cross-factors. It takes a long time to read and write the hard disk. Each time it is used, it will cause severe wear on the hard disk. For hard disks that already have physical bad sectors, It is aggravated. Practice has proved that low grid will accelerate the retirement of hard disks with physical bad sectors. For logical bad sectors, there is no need to use low-level programs as a means of repair. In addition, the low cell will completely erase all the data in the hard disk, this process is irreversible. Therefore, the low grid can only be used as a last resort. The hard disk after the low grid can be used after the advanced formatting using the Format command.
