Common Computer Hardware Troubleshooting
A. HARDWARE CHECKING
1. RAM chip failure
RAM chip failure usually detected when a long beep sound is produced by the motherboard when user trying to start the computer. In most cases, reinsert the chip will fix the problem. But sometimes the chip has to be replaced to a new one, and in some other cases the problem actually caused by the RAM chip clot on the motherboard. In this case, we have to use other slot that available.
2. Graphic card failure
Graphics card failure is refers to 3 beep sound produce by the motherboard. Usually by reinserting the device to its slot will fix the problem. In some cases computer don’t produce display even though the CPU run well, we can try to use other good graphic card to make sure the problem really comes from the device and not monitor or the slot (AGP or PCI).
3. Hard drive failure
Some computer didn’t detect operating system at startup. Other than missing or corrupt files in operating system, one of the major factors that caused this kind of problem is the motherboard failed to detect the existing hard drive. We know that the motherboard failed to detect the hard drive when the boot screen displays None for primary master (depends on where you put your hard drive) or sometimes display unknown name.
Check the jumper behind the hard drive, make sure it is correct. Sometimes CS (cable select) is not a good setting to use, it is better for us to give a specific status for the hard drive. If you only have one hard drive, make sure it is set to single master at primary ide cable, this is the best setting to prevent failure detection in future. And if you have two hard drives, make sure the first one is set as master with slave present while the other one is set as slave. The best setting is master hard drive at the end of the ide cable while the slave is at the centre of the cable. Then check the BIOS setup, make sure that setup is always boot the hard drive that content operating system.
If all these still failed, try to change the ide cable to a new one and make sure it is connected properly. Other than that, touch the hard drive when the computer on to see if it really running or not. If you can’t feel the vibration, try to check the power cable from the power supply.
4. Network card failure
There are two factors that caused user to can’t log into network besides the setting in Windows. One is data point and another is the network card itself. The data point must have not activated or having problem with the cable or somehow disconnected if we see that the network card LED didn’t glow. While the network card failure can be detected by looking at device manager. Try to reinsert the device or detect manually using hardware detection.
5. Motherboard failure
Motherboard failure usually the last thing to mention about since we can only concluded it is the motherboard when other test above failed.
