If, after inserting a CD or DVD into the drive, the computer freezes, it means that it could not immediately read the data on the disc. Freezing is a consequence of the fact that the computer is trying to solve this problem by changing the reading speed.
This often happens with damaged disks, less often - the problem is in the drive itself. If your attempts to read a disc for too long cannot be crowned with success, it is better to remove the disc from the drive and test the drive by inserting another disc with information that does not have visible mechanical damage - scuffs, scratches, etc.
It so happens that very important information can be stored on a damaged disk. And if the computer drive cannot display the contents, you can try to read such a disc on another drive or using special programs designed to read damaged discs.
Regular date crashes on computer
To maintain basic computer settings, the motherboard comes with a small battery. She is responsible for counting the time, because the required date and number are automatically set even when the operating system is installed. And if the battery starts to run out, then the basic settings periodically return to the factory settings. Replacing the battery on the motherboard is one of the cheapest computer breakdowns.
