How is the computer diagnosed on its own?
In the life of any person, there may come a time when his faithful PC refuses to work anymore. This is not an excuse for panic, in most cases a simple computer diagnosis can solve the problem. Independently to hold it will not be difficult.
If the coolers on the system unit turned on, but the light bulbs on it did not light up, not a single sound was heard, and a frightening blackness appeared on the screen of the monitor, then most likely you will have to change the motherboard.
Computer diagnostics continue, if after switching on the system issued one short signal, the BIOS considered all the basic physical parameters, such as memory, the number of hard disks, etc., then you can be sure that everything is in order with the "hardware".
Another possible reason for PC failure is the problem in the disk system. If an inscription appears on the monitor like "Non system disk or disk error", then think about it several times before proceeding with the recovery. Incorrectly performed computer diagnostics can lead to a failure of the entire system as a whole, as well as to the loss of all personal data on the hard disk.
First, you need to enter the BIOS and check whether the hard disk is detected. To log in immediately after starting the download, press the "del" key. The structure of the BIOS is diverse, but the very first menu always indicates all the connected and used storage media, the current time and date. If the hard drive is listed there, then a simple computer diagnostics will not help here. It will be necessary to use various applications, through which the computer is diagnosed. The program scans the disks and finds in them "broken" sectors, which are then restored.
Summing up, it can be noted that not every malfunction in the PC should provoke a trip to the service center. Time spent diagnosing your computer will save you time and money.
