The southbridge typically implements the slower capabilities of the motherboard in a northbridge-southbridge chipset computer architecture. In systems with Intel chipsets, the southbridge has been named I/O Controller Hub (ICH) and later replaced by Platform Controller Hub chipsets. In older Intel/AMD architectures the southbridge is usually ...
Failing motherboard. Failing processor. Failing memory. Failing I/O controllers, on either the motherboard or separate cards. Failing I/O devices. Inadequate or failing power supply. Cooling problems are usually obvious upon inspection. A failing motherboard or processor can be identified by swapping them with functioning parts.
Other legacy connectors that are slowly being phased out of modern ATX motherboards include 25-pin parallel ports and 9-pin RS-232 serial ports. In their place are onboard peripheral ports such as Ethernet, FireWire, eSATA, audio ports (both analog and S/PDIF), video (analog D-sub, DVI, HDMI, or DisplayPort), extra USB ports, and Wi-Fi.
The threat surface of a USB however is bi-directional and a malicious peripheral device could attack the host. An infected edge device cannot easily be mitigated by WebUSB API's. In many device configurations trusted USB ports are used to deliver firmware upgrades and a malicious edge device could grant attackers persistence in a system. [11] [4]

On 5 January 2010, the USB-IF announced the first two certified USB 3.0 motherboards, one by ASUS and one by Giga-Byte Technology. [22] [25] Previous announcements included Gigabyte's October 2009 list of seven P55 chipset USB 3.0 motherboards, [26] and an Asus motherboard that was cancelled before production. [27]
The actual key depends on specific hardware. The settings key is most often Delete (Acer, ASRock, Asus PC, ECS, Gigabyte, MSI, Zotac) and F2 (Asus motherboard, Dell, Lenovo laptop, Origin PC, Samsung, Toshiba), but it can also be F1 (Lenovo desktop) and F10 . [50] Features present in the BIOS setup utility typically include:
A hard disk drive failure occurs when a hard disk drive malfunctions and the stored information cannot be accessed with a properly configured computer. A hard disk failure may occur in the course of normal operation, or due to an external factor such as exposure to fire or water or high magnetic fields , or suffering a sharp impact or ...
