Six months ago, I wrote, "How does a computer start?" To explore the role of BIOS and master boot records.The article does not cover the operating system and is only relevant to the Board's onboard program. Today, I would like to write down and discuss what happens when the operating system takes over the hardware, that is, the startup process of the operating system.This part is more interesting. Because in the BIOS phase, the behavior of the compute

drive to AHCI, otherwise the performance loss is not small, AHCI is the Serial ATA Advanced Master interface of English abbreviation, it is Intel's leading technology, it allows the storage driver to enable advanced SATA features, such as native command queuing (NCQ) and hot-swappable. After AHCI can play the potential performance of SATA hard drive, theoretically can increase 30% of the hard disk read and write speed, because the mechanical hard drive internal transmission rate is low, AHCI ca

parallel processing ability. The actual effect is reflected in the removal of the edge of the object Sawtooth phenomenon, as well as the rendering speed of various effects. The birth of a stream processor In order to realize the requirement of unified rendering, programmable and callable of GPU internal unit, the efficiency of GPU is improved, the pixel pipelines (pixel rendering pipeline) and vertex pipelines (vertex coloring unit) are unified to become streaming Processor (stream processor)

Notebook can not be on the net, in addition to the network card driver update, there may be a network card closed, most laptops have a physical switch with the network card, but also from the BIOS on or off the network card, physical switch is not more introduced, the culture and education how to open and close the Win7 pure version of the 1, restart the computer, in the boot process constantly press Del (different computer into the BIOS method is not the same), into the BIOS; 2, after

Reason 1, the motherboard chipset controls the onboard network card, video card, USB and other interfaces, but also control the motherboard of the IDE or SATA hard disk data interface, if the interface is not damaged, then this problem is generally due to the motherboard chipset caused by the motherboard chipset caused by the cause of 2 times to recognize the hard drive, It is recommended that ghost Win7 system users try to replace the motherboard or

Before introducing the article, let's introduce the Board integrated sound card, we know, the sound card is our w764 flagship system download computer can sound a key driver, is also our Win7 flagship computer essential equipment, and integrated sound card is one kind. In the view of many users, this integrated sound card use is not very high, it seems that there is not much significance, but it will waste our system space, if the integrated sound card off, will improve the speed of the system?

In general, we w764 a flagship version of the computer to download the boot will be very simple, just press the Win7 flagship version of the power button can be a key to the boot, but in the process, we still will occasionally appear some problems, For example, the boot of the black screen and blue screen failure is some of the more typical boot failure. But have you ever seen a Win7 flagship version that does not boot up and appears with a PXE mof:exiting PXE ROM? Today, a friend encountered su

Some users in the Windows7 64-bit system inside and did not find the NIC to open, in fact, everyone here can start in the computer, in the BIOS to open the network card. For those who do not know how to open the Internet card, you can open the card tutorial in this article in the BIOS to understand. The specific tutorials are as follows: 1, first in the Windows7 64-bit system when the fast key disk F1 or delete key value into the BIOS panel; 2, then in the "BIOS" Panel selected "Device" in th

1. First of all, we need to go into the Win7 flagship system BIOS setup interface, the operation is very simple, we just need to restart their own Win7 flagship computer, and then the computer appears on the screen when we press the Keyboard del button, so you can enter the BIOS setup interface. 2. After that, we select the Network setup option in device in the presence of the BIOS setup interface, then select the onboard ethermet Controller

To turn off the Win7 motherboard integrated sound method: 1, in the computer boot on the keyboard press del key into the BIOS interface 2, in the BIOS interface to find "Chipset Futures Setup", and then click Enter, find the right side of the onchip sound option, and then set it to Disabled, and then click F10 Save; 3, after entering the BIOS, move it to the "Advanced" tab inside, find the "I/O Device Configuration" option below, click the Enter key directly, and find the lower "

A user is Lenovo notebook Win7 64-bit flagship version of the operating system, in the computer boot check found no network card equipment, resulting in the network can not connect the problem, if not found the network card is very likely to be disabled without opening, in fact, we can through the BIOS to enable the network card, For less exposure to the BIOS interface, how to set up a little rusty, the following peas hands-on teach you through the BIOS to enable the network card bar. Lenovo no

noise will become larger. As with most GeForce GTX 600 graphics, this 3GB onboard clock is set to 1502MHz, but it has a 384-bit bus similar to GTX Titan, rather than the 256-bit memory bus used on GeForce GTX 680 and GTX 670, so , GTX 780 has a higher bandwidth. Dimensions, noise and heat dissipation: GeForce GTX 780 (26.7 cm) is smaller than GTX Titan (27.7 cm), but it inherits Titan's excellent cooling system and high quality polishi
