Analysis and elimination of CPU overheat fault

I would like to borrow this summer crazy play a computer game, but their own do not make up the love machine but twice off the chain, so I feel quite annoyed. and two failures are due to CPU cooling, fortunately, the CPU processor of my computer has overheating protection function, will not burn it, at the same time this also gave me a wake up: summer, we must pay attention to the heat of love machine.

Malfunction One: The dust becomes the murderer frequently freezes the real murderer to appear

The first day of the holiday, I can not wait to play the computer game, but not after one hours, the computer unexpectedly restarted. The beginning of the author did not, after the machine started, continue to play the game. Strange thing happened: After playing the game in the process of the computer frequently crashes, and from the first one hours into more than 10 minutes, this is what is going on? The author of this computer just a year, because usually in school, the computer at home and did not use too long time, will not be able to use it.

Learn more than six months of computer maintenance and maintenance, this time to come in handy. Through the fault surface, after a lot of analysis, finally determined that the CPU is poor heat dissipation, resulting in the CPU overheating protection function open and frequent restart. The author's computer configuration is the Intel Pentium 4 630 processor, 1GB ddr2-667 memory, gigabyte 945P-G motherboard, 160GB SATA hard drive, Rainbow 6600GT graphics card, configuration can be said to be the mainstream. But after running for just over a year, unexpectedly overheating now, why?

Opening the cover, the writer was startled. This is a computer ah, has been "unearthed". The amount of dust piled up on the CPU heatsink is equally appalling in other parts. To think it over, the situation is inevitable. The weather in the north is more serious, and recently there has been a large range of sandstorm weather, the home is also a lot of natural into the soil. Because the computer put no one to move at home has been nearly a year, resulting in too much dust in the chassis, not all CPU radiator, has accumulated a lot of dust, two plus August such a hot ghost weather, not the crash is strange.

After the discovery of the problem, the author immediately inside the case of the overall cleaning, all the accessories removed, with a brush swept all over the cracks and then reassembled, which solved the fault.

The author's own things are solved, did not expect two days after the classmate's computer also appeared the same problem, the computer old crash, find the author to help solve. Needless to say, the cause of the malfunction must be the same as my computer. But after opening his case, the author found that the dust phenomenon has changed, unlike my case is just pure dust, but absorbed the dust of water vapor, with the hands of a touch on the skin, the dusky, very dirty.

Cleaning up his case is more complicated, because the dust inhaled the water viscosity becomes big and difficult to sweep off, finally had to use brush dip water to clean. In order to prevent short circuit, and then dry with a hair dryer for half an hour.

Why does the dust in his chassis suck water? In fact, it is very good to understand that the summer rainfall in Beijing is also quite adequate, the air humidity suddenly increased, so the dust will be full of moisture absorption. I am very glad that their chassis clean up in time, if another few days, dust into the soil, it is likely to make components short-circuit and lead to hardware damage.

Through these two events, I feel the need to remind all computer users, especially the friends in the north, in the spring and summer season must open the chassis to clean up the dust completely. In the process must be removed from all parts of the separate cleaning and assembly, because the dust is everywhere, a little omission is a hidden danger, if possible, the power supply shell should be taken apart, will find that there is a lot of dust.

Failure two: Heat sink card buckle does not die cause CPU overheating frequent reboot

The cause of this fault is entirely due to the author's effect. In front of the author for their own love machine thoroughly clean up, so follow the steps carefully will be the parts reassembled. Press the Host power button, with a crisp "drip" sound, computer successfully launched into the familiar Windows operating interface, just as the author secretly lucky to be good fun back to the game, the computer's monitor was suddenly shut down at this time, and the host also automatically shut down, there is no reflection of what is going on.

So I reset the power switch and the computer started. The power indicator light is on, the CPU fan is turned, and the optical drive led flashes. A few notes clock passed, the computer like faint, the monitor is still in standby state, a little image is not, the host did not issue "beep" of the normal boot sound. There is no continuous "tick beep---" sound, you can conclude that the memory must be no problem. I pressed the optical drive Switch window key, the optical drive can be normal access. Thought, impossible ah, there is no problem, is there a problem with the graphics card?

Turn off the power, a few twisting screw action, the chassis side panel removed, hand-touched the graphics card radiator, there is a slight temperature, said the obvious card just work? In order to find out the reason, the author hastened to a friend to borrow a piece of the normal use of the graphics card, a turn of the insert, the graphics card installed, full of confidence opened the power. Look at the power led, aiming at the display, listen to the horn sound, a little reaction is not, another heavy blow.

It seems that the problem is not graphics card, then where is the problem? It seems that my fur computer knowledge is really not enough! I am not a person to admit defeat, and never to the computer failure to bow. So, I put the optical drive, hard drive and other equipment all folded down, but the fault is still. Now the CPU is not moving, it will not be the problem of the CPU.

Just ready to start to dismantle the CPU, suddenly found that although the CPU radiator has been on the CPU, but due to carelessness, fixed CPU card buckle did not buckle dead. Could it be the cause of this? So the CPU heatsink card buckle die, press the chassis power supply, there is a reflection of the monitor, although unable to find the hard drive and other devices can not start, but the display has been seen on the English characters.

After the shutdown, all the accessories will soon be installed, and then turn on the power, the problem is completely resolved. Play with Love machine for a few weeks of the game, everything is normal, never lost a chain. Through efforts, the author finally put the computer to the training clothing.
