When you try to boot your computer it hangs after post when you?
When you try to boot your computer,it hangs after POST, When you access the UEFI setup program,you see that the date is several years behind and the time is set to 12:01 am. What is the most likely problem? The motherboard battery has failed. After arriving at work,you turn your computer to begin your day.
Which expansion slot is best for high end?
PCI Express: The best type of expansion slot to have in your PC is the PCI Express, also written as PCIe. Without boring you, the PCI Express type of expansion slot communicates with the motherboard, and therefore with the microprocessor, both quickly and efficiently.
Which function does a motherboard’s chipset perform?
Living on the motherboard, a PC’s chipset controls the communication between the CPU, RAM, storage and other peripherals. The chipset determines how many high-speed components or USB devices your best motherboard can support.
What is the role of the CMOS in a modern computer?
The CMOS is a physical part of the motherboard: it is a memory chip that houses setting configurations and is powered by the onboard battery. The CMOS is reset and loses all custom settings in case the battery runs out of energy, Additionally, the system clock resets when the CMOS loses power.
What causes POST failure?
A POST failure can be triggered by some reasons, for example, new hardware conflicting with old hardware, failing or bad hardware device, electrical shorts or incompatibilities.
How do I fix BIOS freeze?
How do I fix BIOS freeze? Troubleshoot the cause of the BIOS error message you see on the monitor. Disconnect any USB storage devices and remove any discs in any optical drives. Clear the CMOS. Test your power supply. Reseat everything inside your computer case.
Which PCIe slot is fastest?
PCIe 4.0 is twice as fast as PCIe 3.0. PCIe 4.0 has a 16 GT/s data rate, compared to its predecessor’s 8 GT/s. In addition, each PCIe 4.0 lane configuration supports double the bandwidth of PCIe 3.0, maxing out at 32 GB/s in a 16-lane slot, or 64 GB/s with bidirectional travel considered.
What does PCIe stand for?
PCIe is short for “peripheral component interconnect express” and it’s primarily used as a standardized interface for motherboard components including graphics, memory, and storage.
What was before PCI?
ISA. ISA is the precursor to PCI. Standing for “Industry Standard Architecture” It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called “ISA PnP” peripherals.
How do you troubleshoot system power problems?
Plug the PSU power cable into a wall socket or surge protector, and turn on the computer. Most power supply models have a light on back of the unit that glows when it’s powered on. If it doesn’t light, try a different power cable and a different socket to eliminate those items as the source of the problem.
What does chipset mean on motherboard?
The chipset is a silicon backbone integrated into the motherboard that works with specific CPU generations. It relays communications between the CPU and the many connected storage and expansion devices.

What are CMOS settings?
CMOS (short for complementary metal-oxide-semiconductor) is the term usually used to describe the small amount of memory on a computer motherboard that stores the BIOS settings. Some of these BIOS settings include the system time and date, as well as hardware settings.
Why is CMOS important in BIOS?
For the BIOS to work properly, it needs to keep information about your system handy. It stores your system’s information and its settings in a memory chip referred to as a CMOS chip. Computers with CMOS RAM will also have backup batteries to keep the CMOS settings.
What CMOS means?
Like CCDs, CMOS(Complementary Metal Oxide Semiconductor) sensors are semiconductor image sensors that convert light into electrical signals. CMOS sensors are semiconductor light sensors like CCDs.
How do you fix a computer that won’t start up?
What to Do When Your Computer Won’t Start Give It More Power. (Photo: Zlata Ivleva) Check Your Monitor. (Photo: Zlata Ivleva) Listen for the Beep. (Photo: Michael Sexton) Unplug Unnecessary USB Devices. Reseat the Hardware Inside. Explore the BIOS. Scan for Viruses Using a Live CD. Boot Into Safe Mode.
What causes a computer not to boot up?
Common boot up issues are caused by the following: software that was installed incorrectly, driver corruption, an update that failed, abrupt power outage and the system did not shut down properly. Let’s not forget registry corruption or virus’ / malware infections that can completely mess up a computer’s boot sequence.
What is no boot issue?
No boot means that the computer isn’t functioning as expected and, while lights can be On or Off in the motherboard, no video is display on the screen. Both terms are interchangeable and are used to describe issues in which the computer doesn’t start.
Can BIOS cause computer freeze?
In several cases, modifying BIOS settings can cause serious issues and may put the system in the freeze mode. Overclocking system processor or RAM causes instability problems. If this is the case that is causing the system to freeze, reset the BIOS settings to default.
Why does my computer randomly freeze?
Why does my computer keep freezing? Typically, it will be a software-related issue or your computer has too many programs operating at any once, causing it to freeze. Additional issues such as insufficient hard-disk space or ‘driver’-related issues also can cause a computer to freeze.
