During the POST, the BIOS must integrate a plethora of competing, evolving, and even mutually exclusive standards and initiatives for the matrix of hardware and OSes the PC is expected to support, although at most only simple memory tests and the setup screen are displayed.
TechPowerUp Memtest64 is a free lightweight, standalone utility that lets you check your system memory for problems at the hardware-level. It has a graphical interface, and can be run from within Windows.
Memory hardware errors can cause major application crashes, blue-screens of death (BSODs), and data corruption. It is caused due to either faulty hardware, or bad memory timings/frequency. Memtest64 lets you test your memory without having to pull out an MS-DOS boot disk. The utility loads your physical memory with test-patterns, and can push other applications into the pagefile to free up memory for testing.
It can also be useful to overclockers who are looking to maximize memory performance by playing with timings and DRAM speeds.

MemTest86 is the original self booting memory testing software for x86 computers. Wifi signal 4 2 2 3. Supporting both BIOS and UEFI, with options to boot from USB. A bad memory module (RAM) can cause unpredictable behavior in a Windows system, including the dreaded blue screen of death. If you suspect that your RAM may be faulty, you can run a memory test.

The latest version is available in the downloads section.The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere. It cannot get it from the operating system because the operating system is located on a hard disk, and the microprocessor cannot get to it without some instructions that tell it how. The BIOS provides those instructions. Some of the other common tasks that the BIOS performs include:
Memory Test Slums
- A power-on self-test (POST) for all of the different hardware components in the system to make sure everything is working properly
- Activating other BIOS chips on different cards installed in the computer - For example, SCSI and graphics cards often have their own BIOS chips.
- Providing a set of low-level routines that the operating system uses to interface to different hardware devices - It is these routines that give the BIOS its name. They manage things like the keyboard, the screen, and the serial and parallel ports, especially when the computer is booting.
- Managing a collection of settings for the hard disks, clock, etc.
The BIOS is special software that interfaces the major hardware components of your computer with the operating system. It is usually stored on a Flash memory chip on the motherboard, but sometimes the chip is another type of ROM.

When you turn on your computer, the BIOS does several things. This is its usual sequence:
- Check the CMOS Setup for custom settings
- Load the interrupt handlers and device drivers
- Initialize registers and power management
- Perform the power-on self-test (POST)
- Display system settings
- Determine which devices are bootable
- Initiate the bootstrap sequence
The first thing the BIOS does is check the information stored in a tiny (64 bytes) amount of RAM located on a complementary metal oxide semiconductor (CMOS) chip. The CMOS Setup provides detailed information particular to your system and can be altered as your system changes. The BIOS uses this information to modify or supplement its default programming as needed. We will talk more about these settings later.
Interrupt handlers are small pieces of software that act as translators between the hardware components and the operating system. For example, when you press a key on your keyboard, the signal is sent to the keyboard interrupt handler, which tells the CPU what it is and passes it on to the operating system. The device drivers are other pieces of software that identify the base hardware components such as keyboard, mouse, hard drive and floppy drive. Since the BIOS is constantly intercepting signals to and from the hardware, it is usually copied, or shadowed, into RAM to run faster.
