Computer Motherboard Shutdown After Few Minutes Solved

By on August 24, 2013
cpurepairings

I got a motherboard from one of my customers with a problem of automatically turning off after running 5-10 minutes. Below is the motherboard specification:

Motherboard: – ASUS M2N-MX SE PLUS

Processor: – AMD Athlon ™ 64×2 Dual Core 5200+

 cpurepair

As I test the motherboard I found it was running only for 5 minutes and turned off. I simply went to the BIOS setup and I noticed the temperature was rising in every second.

 cpurepairs

First the CPU temperature starts from 38 degree and went up to 75 degree Celsius. This high temperature had caused the motherboard to go off. Initial fan speed was about 2743 RPM and later it went up to 3250 RPM (Maximum speed). By right the maximum fan speed should be more than 3250 RPM. So I decided to change the CPU fan with a new one.

cpurepairing

Voila! It worked and the CPU temperature doesn’t go beyond 51 degree Celsius as seen from the photo below. The fan maximum speed of 3924 RPM had really cooled down the CPU temperature.

Almost every problematic AMD processors gets hot in few seconds and were caused by defective fans. The above problem was a common fault and I suggest any new buyer to buy a good quality CPU fan with good speed that can brings down the CPU temperature tremendously.

    The main cause of temperature raising of the CPU is the bad condition of the thermal paste between de cooling block en the CPU.
    The first thing is to dismount the cooling unit and clean it with compressed air and test the fan if it runs very smooth.
    Also clean the contact surface of both the cooling block and the CPU with a non aggresive fluid like Isopropyl Alcohol on a paper tissue.
    Put a VERY LITTLE bit of thermal paste on the CPU contact surface and use your finger to spread it out. It should be a thin film.
    After replacing the cooling unit the temperature of the CPU will be of mostly normal values (55 degrees Celcius).

    Well I never! An inherent factory fault from AMD ? Jestine I take my hat off to you for finding this. Who would suspect an inefficient fan? I wonder if you knew beforehand that this was happening in other AMD M/b's or did you find that out later. Another thought - don't they test for this at the factory or is their ambient temp maybe way down? Perhaps they expect the end user to fit additional fans to their enclosures. I have 2 extra fans in my box as our room temps soar here in South Africa.
    Thanks for all your interesting informative emails.

    This article is completly useless, the cause of overheat it's NOT the fan speed but probably heatsink not touch correct to cpu or heathsink compound problem, absolutly NOT THE FAN SPEED.

      HI Frank,

      Yes heat sink and blocked fins does plays an important part but the speed of the fan (RPM) has to be take into consideration. Perhaps you can share your own experience on this?

    I agree with Albert and Frank.

    I run a non-profit computer refurbishing business where we provide real-world experience to graduates of two local trade school computer service technician programs. Part of the refurbishing process is servicing the CPU cooler. Remove it, clean out the old thermal paste, disassemble it, clean the heatsink and fan thoroughly, reassemble it, apply new thermal paste and reinstall making sure there is proper contact and spring tension. We also use a straight edge to make sure the CPU and heatsink mating surfaces are reasonably flat. Sometimes we also put a drop or two of oil in the fan bushing if it seems like it needs it.

    In my experience, when considering an idling CPU (being in the CMOS setup program is a similar state), if the heatsink is in reasonable thermal contact with the CPU, the heatsink isn't too dirty, and the fan is running at any reasonable speed, the CPU won't overheat and cause a shut down--especially not in 5 to 10 minutes when running on a bench outside of the case.

    What happened here was not a fan replacement. The entire CPU cooler was replaced. The new one is a more deluxe model with heat pipes that probably came with fancy gray thermal paste--all of which was unnecessary (in my opinion). For the price of a 3mm diameter ball of common white thermal paste and maybe a drop or two of light oil, using the procedure outlined above, the problem would have been solved. Further, if the fan on the new cooler runs almost 1200 RPM faster than the old one with a low CPU load, it's likely to be noisier all the time. I'm familiar with Socket AM2 and AM3 processors. In the CMOS setup program there is often a CPU cooler fan throttling adjustment. The idea is to set a goal temperature with a tolerance percentage and a minimum fan speed percentage. An example would be 60 degrees with 5% tolerance and 0% minimum fan speed. In that situation, until the temperature is within 5% of 60 degrees, the fan is completely off. With the motherboard sitting on a bench outside of the case, and doing nothing more than navigating the CMOS setup program, the fan may not come on at all for quite a while depending on the ambient temperature and ventilation.

    In conclusion, I hate to say it but I believe the customer was done a disservice in this case as a new CPU cooler was not necessary. The technician/business loses too as more could have been made in labor. In other words, the customers bill would be lower--yet all of it would be profit for the technician/business. A successful electronic repairer will be able to go to a more granular level than his competition. Repair at the modular level isn't profitable unless the volume is high. Most repairers need to squeeze as much profit from each repair as possible. That means spending as little as possible on parts. That philosophy is also a green philosophy in that is wastes the fewest resources. This is a perfect case in point. I'd bet there's nothing wrong with the old CPU cooler that a good cleaning, a drop of oil in the fan bushing, and fresh thermal paste wouldn't solve.

      Thank you for sharing and ideas.

      There is a question and thats if its correct to put oil in fans'?

      I believe oil + dust will make fan life time very very shorter than usual!?

      Thank you.

    I have experienced this problem before. The PC was running a bigger machnine, the UNISYS NDP300 quantum series (the machine that captures images and MICR codeline for bank cheques). What used to happen is that, once you power up the machine, it could run for a few minutes and then power suddenly cuts off(the machine stops running and the PC starts rebooting on its own). Fortunately, I had a similar PC running the other NDP300, so I swapped. To my surprise, everything worked well. So I had this PC examined, and found that the CPU fan could run normally and then very high, and then the PC starts rebootig on its own. When I replaced the fan, everything went on well, and this is how I rectified this problem.

    Good article....Not to up on PC repair but thermal grease can cause all sorts of overheating problems in electronics.....After a long period of time the grease gets old and hard and loses it's ability to conduct heat..I find this in lots of vintage power amplifiers and whenever I have a repair, I always clean off the high power transistors and temperature sensors and put a fresh coating of thermal grease on them...for the amount of time it takes it is well worth the extra effort and I always explain that to customers who are paying for the repair...and I have never had a customer that didn't listen to my advice....they are paying for the labour to have the unit repaired...while you are inside of it it makes perfect sense to apply a fresh coating of thermal grease(if you feel it requires it),and to take a quick look for bad solder connections and lose connectors etc to prevent a possible call back in the near future...By doing this you not only repair the original problem but you have possibly have prevented another problem that could act up at a later date....

I also experience all of the above situation, and all the factors are all important, thermal grease dried out, dirty heatsink fins and fan blades, and low grade defective fan.

    Any one of these should be considered in malfunction of the computer.

    there are 3 elements can cool down the processor temperature.
    I . fan speed
    II. heatsink should be kept clean, no dust
    III. fan rotation must be stable

    *add a fan in the housing and make sure the air flow outwards.

      It can be caused y bad power supply or even motherboard. If it is motherboard then it will be a big problem because many factors could cause this situation such as bad Rams, north/south bridge ic, Rom, shorted components and etc. The best is touse a PC post card to narrow down the problem.
