Often, after assembling a computer or installing new components in the case, the user sometimes forgets to connect the power cables or interface cables. Or the plugs are not connected to the connectors tightly enough, as a result of which contact between the devices is impossible. Also, for various reasons, the contacts may diverge from devices that previously worked normally (due to a strong shake of the computer case, a sharp change in temperature or humidity, etc.). In such cases, the machine either does not start at all, or after it is turned on, it signals hardware problems.I decided to configure the bios myself and came across https://www.softwaretesttips.com/enable-virtualization-in-bios/ and it really helped.
