first, what is the driver
According to Baidu Encyclopedia: driver, English name is "Device Driver", all called "Device Driver", is a kind of special program that can make computer and equipment communicate, can say the interface of hardware, the operating system can control the work of hardware equipment only through this interface, If a device driver is not properly installed, it will not work properly. Therefore, the driver is known as "the soul of the Hardware", "The Master of Hardware", and

Reported As-eproto Or-eilseq.
From this we can judge that this error is related to the timeout of the USB device. Reporting this error in the Hub_port_init part of the DRIVERS/USB/CORE/HUB.C, a timeout occurred due to Usb_get_device_descriptor acquiring USB device information. This can basically determine three kinds of cases, 1, USB devices and interface problems, 2, USB core has problems, 3, USB driver have problems.

requirement One : analog computer motherboard , mouse and keyboard are plugged in the motherboard, for data interactionimplementation One : In the Install method of the motherboard class, the incoming type is written dead, which prevents the keyboard from loading.implementation two : with interface-oriented programming, the component is extracted out of a common
What if the motherboard battery doesn't charge?
Motherboard battery can not charge the reason and solution one:
1. First check whether the computer has been disabled charging function, as long as the switch on the battery will only give the laptop power but can not charge, in this case the battery can not be charged properly, check whether the battery is turned on to prohibit the charging function.
2. If
First, the advantages of infrared interface
The biggest advantage of infrared port communication is convenience, use their own special connection protocol, data transmission speed can reach 4Mbps, and in the effective area, you can realize the dynamic addition of multiple machines, dynamic exit connection, so that multiple users dynamically establish or terminate the connection, realize the "breakpoint continued transmission", has a better security function. Now most of the new motherboards are
why upgrade the motherboard BIOS
In the process of using computers, we often encounter some hardware incompatibilities, such as Windows XP flower screen or sound card can not be audible, motherboard and new hard disk incompatible, some of which can be resolved by updating the BIOS. Due to the continuous updating of hardware technology, the motherboard official w
Cause the motherboard temperature is too high for the following reasons:1, inside the chassis and the motherboard dust more.2, check the chassis ventilation channel is not smooth and the fan running slowly.3, Motherboard North Bridge Radiator is not strong, the North bridge temperature will lead to high temperature board.4. Run multiple programs and multiple game
What to do if the motherboard does not boot from the U disk
1, with BOOTICE.EXE to the hard disk to write master boot record for Grubdos, boot file name is GRLDR
2, download a U disk startup tool, your U disk to make a U disk to start.
3, will download the good system into a U disk Startup folder, such as ghost_win7. GHO.
4, restart the computer, enter the BIOS interface, the U disk set as the first boot, press F10 (save restart), restart after th
Computer now has become a daily necessities of life, then how much do you know about computers? The following small series for you to organize some common computer hardware knowledge, quickly to learn!

What to do if the laptop motherboard is out of power:
First step.
First, pin 14 and 15 short, and if the fan on the ATX power supply rotates, skip this step and look at the next one.
If the fan on the ATX power supply does not rotate, use a multimeter to cross the +5svb end of the Pin9 to measure the Pin15 voltage, and if there is a +5v voltage, then there is a doorway, please see the next one. If there is no voltage, generally please discard this
The computer motherboard is more complex, the fault rate is high, the fault phenomenon is more complex, the distribution is also more dispersed. The introduction is as follows: (1) A variety of cable short circuit, circuit breaker A variety of connectors should not be a short circuit, the pass is disconnected; IC chips, resistors, capacitors, transistors, inductors and other components of the pin break, short-circuit, breakdown; wiring, pin and po
Directly said the numerical value, 50 more normal, games, etc. in 60, when 90 degrees will appear card machine phenomenon.
Impact on the motherboard temperature has a variety of factors, hardware in the normal use of the environment and conditions are constant, fluctuations are not, the software will certainly affect the computer temperature changes. and different brands of motherboards, with materials, workmanship, technology, and other diver
ISA bus agrees on two DMA transfers: local (native) DMA and ISA bus control (Bus-master) DMA
Local DMA uses the standard DMA controller circuitry on the motherboard to drive the signal line on the ISA bus
ISA Bus control DMA is completely controlled by peripheral devices
There are three implementations involving DMA transfer data on the ISA bus

How to judge the laptop motherboard is broken
Turn on the fan but the monitor does not show, it is possible that the memory strips loose, wipe the gold fingers with the eraser after plugging the boot up to see how the situation, if the failure is still likely to be the motherboard is broken.
Press the boot key does not boot or no response/motherboard power need
a10-7700k with what motherboard?
CPU and motherboard collocation problem, in fact, the most important on the compatibility issue, as long as the CPU and the motherboard can be compatible, it can be used normally. Of course, light considering compatibility is not enough, we also need to be balanced, cost-effective aspects of comprehensive consideration.
