Everyone hopes for a computer sony vgn-sz360p laptop cpu fan boot can immediately enter the Windows system instead of waiting, but for a variety of reasons often fail to fulfill a wish, even a boot will crash situations occasionally. In fact there are times when Windows start slowly and is not itself, but some equipment or software cause, look below to slow down the system startup eight reason, then check your computer is there is a similar problem!
1. USB hard drive and scanners
If a computer installed scanners, or at startup time has been connected to the USB hard drive, so might as well try to put them off, look at start-up speed is there change. Generally speaking, due to the USB interface speed slower, so the corresponding equipment will be on the computer boot speed has more obvious influence, should try to start again after connect USB devices. If there is no USB devices, it is recommended that directly in the BIOS setting USB function closed.
Tip: because when Windows startup for each drive (including cd-rom) for testing, so if drive places the CD, will increase the computer start time.
2. Irritating network card
If the Settings, nic also can significantly sony vaio vpc-eb15fm laptop cpu fan affect the system startup velocity, if you don't have a computer network card, then direct will nic pulled out, lest affect system startup velocity.
If your computer is connected in the local area network, how to install the driver for the network card, by default system will automatically through the DHCP to obtain IP address, but most of the company local area network (LAN) and no DHCP server, so if the user set to "automatic get IP address", the system at startup time will continuously in the network search DHCP server, until a IP address or timeout, nature will influence the start time, therefore LAN users the best for his own computer specify a fixed IP address.
3. Documents and printer sharing
Some installed Windows XP professional version of the computer also can appear start very slowly, or even reached 1 minutes and 40 seconds! System seems to crash, login system, desktop to also do not appear, the computer is like stop reaction, 1 minutes to normal use. This was due to the use of Bootvis. Exe program, one of the Mrxsmb. DLL file for computer start added 67 seconds of time!
To solve this problem, want to stop to the Shared folder and printer can: choose "start - > Settings - > network and dial-up connections", right click "local area connection", select "properties", in the open window to clear the connection using the following selected components hp presario cq71 series laptop cpu fan "of the" Microsoft network files and printer sharing "before the check box, restart the computer can.
4. Disconnect don't network drive
In order to eliminate or reduce Windows must be to establish a network connection number, it is suggested that some do not need to use a network drive off, enter namely "my computer", right-click the established mapping a network drive, select "disconnect" can.
5. Hard disk partition too much also have the wrong
If your Windows 2000 not upgrade to SP3 or SP4, and defines the too many partitions, so also can make start become very long, even hang up. So proposal to upgrade the latest SP4, and at the same time, had better not for hard disk points too much area. Because Windows at startup time must load each partition, with partition number increasing, completion of the operation of the total time will continue to increase.
6. The desktop icon will too much trouble
There is too much on the desktop icon will also reduce the system startup velocity. Every time Windows startup and display the desktop, need to find one desktop shortcut icon and loading them, icon, the more the more you spend time of course. Suggest that we will not commonly used desktop icon in a special folder or simply delete!
Tip: some antivirus software provides a system start scanning function, it will take a lot of time, in fact, if you have been opened the antivirus software real-time monitoring function, then start scanning system hp pavilion dv6-3000 series laptop cpu fan to appear a little extra, or will the function prohibited!
7. The font too much dragging
Although Microsoft says Windows can be installed 1000 ~ 1500 swollen hemorrhoid Dan guide bite bit overseas already beat ⑾ value of low dark Nao hemorrhoid Gui ? 00, problems will occur, such as: font from the application's font list disappear and Windows startup speed to drop considerably. In this suggestion will be best in less than or not commonly used font deleted, in order to avoid the accident after deletion, can be necessary backup.
8. Microsoft yourself up "faction"
Remember a Windows XP a patch cause system startup slow news it (such as: code for Q328310 patch will cause Windows 2000 / XP startup and shutdown extremely slow, even may cause the registry lock), visible Microsoft their own hp pavilion dv5-2077cl laptop cpu fan internal the possibility of a small, if you the upgrade a system after the patch, suddenly found the system startup slow, so had better pay attention to the patch is to blame.

What is memory dual channel
Dual channel memory technology is actually a kind of memory control and management technology, it depends on the chipset of memory controller work, in theory can make two the same specifications provided by memory bandwidth doubled. It has not any new technology, has been applied to the server and the workstation system, and just in order to solve the desktop increasingly distress memory bandwidth bottleneck problem it came to desktop motherboard technology front desk. In a few years ago, Intel company has launched a support toshiba satellite l505d-es5025 laptop cpu fan dual channel memory transmission technology i820 chipset, it and RDRAM memory constitute one pair of gold partner, played out and tribulations performance make it become the highlight of the market, but the production cost high flaws caused hurrah don't hit of the situation, was finally out by the market. Because of Intel has given in RDRAM has support, so at present the mainstream chipset double channel memory technology are refers to the dual channel DDR memory technology, mainstream dual channel memory platform Intel is Intel 910, 940, 945 series, and AMD aspects is NVIDIA Nforce2 series.
Dual channel memory technology is solve CPU bus bandwidth and memory bandwidth of the contradiction of low-priced, high performance scheme. Now CPU FSB (front end bus frequency) more and more high, Intel Pentium 4 than AMD Athlon XP to memory bandwidth is of much higher demand. Intel Pentium 4 processor and agp Data transmission using QDR (Quad Data Rate, four Data transmission) technology, the FSB is external clock 4 times. Intel Pentium 4 FSB respectively is 400, 533, 800 MHZ, bus bandwidth respectively is 3.2 GB/SEC, 4.2 GB/SEC and 6.4 GB/SEC, and DDR 266 / DDR 333 / DDR 400 can provide the memory bandwidth respectively is 2.1 GB/SEC, 2.7 GB/SEC and 3.2 GB/SEC. In the single channel memory mode, DDR memory cannot provide CPU need data bandwidth to become the performance of the system bottleneck.toshiba satellite l505d-es5024 laptop cpu fan While in double channel memory mode, double channel DDR 266, DDR 333, DDR 400 can provide the memory bandwidth respectively is 4.2 GB/SEC, 5.4 GB/SEC and 6.4 GB/SEC, here can see, double channel DDR 400 memory just can satisfy the 800 MHZ FSB Pentium 4 processor bandwidth demand. But to AMD Athlon XP platform is concerned, the processor and agp Data transmission technology USES DDR (Double Data Rate, Double Data transmission) technology, the frequency of the FSB is 2 times, its memory bandwidth demand far less than Intel Pentium 4 platform, the FSB is respectively 266, 333, 400 MHZ, bus bandwidth respectively is 2.1 GB/SEC, 2.7 GB/SEC and 3.2 GB/SEC, the use of single channel DDR 266, DDR 333, DDR 400 can meet its bandwidth demand, so in AMD K7 platform use dual channel DDR memory technology, convergence is not much, performance to improve is not such as Intel platform so obvious, the most obvious influence on the performance of or using integrated display chip integrated motherboard.
NVIDIA launched nForce chipset is the first person to turn the DDR memory interface expanded to 128 - bit chipset, then Intel in its E7500 server motherboard chipset also use the double channel DDR memory technology, SiS and VIA also in response, and actively developing this can make the DDR memory bandwidth has doubled since the technology. However, due to various reasons, in order to realize the dual channel DDR (128 bit parallel memory interface) transmission for many chipset makers is no easy task. DDR SDRAM memory and RDRAM memory completely different, the latter has the characteristics of high delay and for toshiba satellite l505d-109 laptop cpu fan serial transmission mode, these characteristics decide the design one support dual channel RDRAM memory chipset and difficulty of the cost is not too high. But DDR SDRAM memory but has its limitations, it itself is low delay characteristic, USES is the parallel transmission mode, and the most important thing: when the DDR SDRAM work frequency higher than 400 MHZ, the signal waveform will often appear distortion problem, all of these design one support dual channel DDR memory system chipset brings a lot of difficulty, chipset manufacturing cost will also improve accordingly, these factors are restricting the memory control technology development.
Ordinary single channel memory system has a 64 - bit memory controller, and double channel memory system have two 64 - bit memory controller, in double channel mode has 128 bit memory a wide, which in theory the memory bandwidth doubled. Although double 64 memory system provided by the bandwidth is equal to a 128 - bit memory system provided by the bandwidth, but both have effect is different. Dual channel system contains two independent, have complementary intelligent memory controller, theoretically speaking, two memory controller can in each other zero delay under the conditions of operation at the same time. For instance two memory controller, A for A, another for B. When controller B toshiba satellite l505-138 laptop cpu fan ready for the next access memory, the controller is A read/write main memory, and vice versa. Two memory controller such complementary "nature" can let the waiting time reduced by 50%. Dual channel DDR two memory controller on the function is exactly the same, and two controller timing parameters can be set separately programming. This flexibility allows a user to use two different structure, the capacity, the speed DIMM memory bank, the double channel DDR simply adjusting to a minimum memory standard to achieve 128 bit bandwidth, allowing different density/waiting time characteristics of the DIMM memory bank can reliably common operation.
Support dual channel DDR memory technology notebook chipset Intel platform have Intel 910, 915, 940, 945,, etc. Series.
Computer could support memory dual channel mainly depends on the toshiba satellite l505-11d laptop cpu fan mainboard chipset, support double channel chipset is described above, you can also view the mainboard chipset material. In addition some chipset in theory support different capacity of the memory bank realize double channel, but the actual or suggest use as far as possible parameter consistent two memory bank.
Memory double channel according to the general requirements on the mainboard memory slot color paired use, in addition some main board and in the BIOS do a Settings, general motherboard manual will have instructions. When the system has realized dual channel, some main board in the power on self test will there be prompt, can look at toshiba satellite l505-10j laptop cpu fan. Due to the self speed is faster, so can't see. So can use some software view, a lot of software can check, such as CPU - z, more compact. In the "memory" of a "channels" project, if here shows "Dual" such words, it means the has achieved double channel. Two 256 m memory constitute a dual channel the effect will be better than a 512 m memory effect is good, because a memory cannot constitute a dual channel.

How to clean dust notebook computer
Notebook,samsung r610 series laptop cpu fan desktop in use after period of time, always can't avoid some dust, such as particle fell on the shell and internal. With too much dust, resulting in heat dissipation not free, this will speed up the computer hardware life. So when your machine is necessary to clean time get oneself begin a la. The following are notebook how to clean.
Cleaning screen
LCD screen always have stains and scratch. To the cleaning, please use the smooth cloth or towel. Plastic and glass cleaner contains ammonia water, may wipe gloss film, so please use from the computer store to buy computer samsung r70 series laptop cpu fan display particular detergent. Will detergent spray in fabric, then use the brush try screen.
Cleaned their keyboard
If you have an assembly brush of small vacuum cleaner, then use it to clean the dirt from the keyboard. Can use compressed air tank blow out into each key-press dust particles between.
Cleaning cooling air vents
According to different types,samsung r700 series laptop cpu fan and the vent can be located in the side of the notebook computer, back and/or bottom. These vents can make the air flow through the computer, thus make the computer to keep them cool. These vents internal accumulation content will hinder cooling process. Purchase a compressed air tank (most computer retailers provide), will vent in the dust particles blow off.
Clean the I/O port
On the back of notebook computer with a series of port.samsung r71 series laptop cpu fan In the washing cooling air vents, using compressed air exhaust all possible accumulation in these port internal and surrounding grime.
