Computer diagnostics From Cyber Attacks
Probably many of you have encountered various computer breakdowns. This article provides a summary of how to diagnose a computer. Where to start and how to find the fault yourself.
Usually, when the computer overheats, it shuts down. This is due to the design of temperature sensors in processors, but there are exceptions. In any case, diagnostics begins with cleaning the components and the cooling system from dust .
Often, the computer restarts due to a malfunctioning RAM. This is due to the inability to read-write to modules. First you need to test the RAM. To do this, you can use special programs, for example memtest.
Hard drive testing
If the computer shows a blue screen before restarting, then it makes sense to check the hard drive for surface integrity and SMART indicators. You can use MHDD or Victoria for this. If errors are found, try replacing the HDD ribbon cable first.
Power supply testing
Diagnosing a fault associated with reboots is complicated by the lack of a pattern. That is, the computer may work for a couple of minutes, or it may not restart for days to fly. In any case, you must first connect a known working power supply.
Checking the motherboard.
The motherboard chipset should not overheat. Its temperature can be viewed in the BIOS, and the characteristics on the Internet. If the chipset overheats and restarts your computer, it is advisable to temporarily change it to a working one for further diagnostics.
