Computer failure due to poor computer power and power supply damage

1, the hard disk appears bad track. Bad power is easy to cause the hard drive to appear false bad, this kind of fault can be repaired by software generally. In such cases, first check the power supply. If the problem is confirmed to be a power supply, the new power supply with reliable quality and stability should be replaced.

2, CD-ROM optical disk reading performance is not good. This situation generally occurs in a newly purchased computer or a newly bought optical drive, when reading a disk with a huge hum, after troubleshooting the optical drive, it is likely that there is a power problem. This failure is usually caused by insufficient power supply, which requires a more powerful power supply.

3, overclocking unstable. Because CPU overclocking work, for the stability of the power supply is very high, if the power quality is poor, after overclocking the computer, often appear sudden panic or restart the phenomenon. Generally as long as a new power to replace a large power on it.

4, computer host often inexplicable wonderful restart. There may be power supply power is not enough, power supply power is not enough to drive the computer all the normal work, resulting in system software run wrong, hard drive, optical drive can not read and write, memory loss, etc., so that the machine restart.

5, computer operation accompanied by "roaring" noise. At this point, the problem generally appears in the power supply fan, making noise increase, if the computer is often not opened, fan dust accumulate too much, it may occur this phenomenon, the solution is to turn on the computer, remove the power, the fan from the above removed, dust. Then reload again, the general noise will be eliminated after the boot.

6, the display has water ripple. It is possible that the electromagnetic radiation of the power supply, is affected by the magnetic field, interfering with the normal display of the display, if long-term attention, the display may be magnetized.

If your computer in use in the above failure, then please check and repair the power supply as soon as possible, otherwise it will cause greater loss.
