Re: cpu fan lo.

Replace the fan ASAP.

Looks like when the system overheated your Windows registry got corrupted. It is possible that someone who knows what they are doing can get a copy of your registry from a restore point and replace the corrupted files using a Linux live CD or BART PE CD.

Hello my Acer Aspire M5640 just crashed it powers up but bios does not boot up can you help thanks I pulled memory out and cpu fan and power supply fan are on

If you have no 'BIOS' startup display, try:
  • Unplug the PC from the main AC power to force a hard reset. Reboot and test.
  • cleaning the memory board 'gold' contact with a white soft pencil eraser and swap them around if you have a couple. Reboot and test.
  • using a single memory board if you have more than one. Reboot and test for each memory board individually.
If you have 'BIOS' startup display, but fail to boot, also try:
  • Check and re-seat all external and internal cables (HDD, USB), and PCI cards (eg. Video)
  • Check Bios setting expecially for HDD
Hope it helps and good luck!

I was running a virus check, asked what to do, I said fix, computer shut down and alarm buzzer came on. now I don't get a boot sound

With the system shut down, unplug the power cable from the power supply. Open you're case and pull the memory from the system wait a minute than reseat the memory. Re-connect the power cable to the power supply. Try booting the system and enter the bios menu. (Pulling the memory will clear any memory resident virus). This has nothing to do with the alarm buzzer sound you heard. Typically the alarm sound is generated by the CPU. It's an audible warning that the CPU is over-heating. The CPU will shut down you're system so as not to damage the motherboard and CPU. (Suggest you check the CPU fan for dust build-up. Use canned air to help remove any build-up. You can also use a clean paint brush to help remove any dust from under each CPU fan blade.
It's also possible that the CPU fan is running far too slow and may need to be replaced.
See page 3-23 in you're user manual.
3-8. PC Health Status.

Open the link provided below for a new heat-sink and fan assembly for a socket 462;
If the CPU fan and heat-sink assembly seems clean it is also possible that the thermal grease / thermal tape between the heat-sink and CPU is too old and needs to be replaced. (Save this check for last).

661fx-m7, It is running ok for 6-10 minutes then pc shuts down with no warning. this can be when it is active or just sitting idle. any ideas please?

This is generally an indication of a processor error. It may be running too hot and stops working when it overheats.

The small fan does not want to run, it runs for a few seconds and stops, my computer keeps rebooting

when the fan stops 2 things are happening 1 the bios sences no rpm speed from the fan or the processor heats up to quickly and the safety in the bios will shut it down. try moving the fan connector to the case fan connector then go into the bios and change the fan settings. this is only a temp fix the fan stopping tells me that the onboard cpu fan regulator is going out and this is a precurser to more problems to the board going out. also just to be certin check the power supply 4 years ago i came across this in a gateway it was weird.

Fatal1ty FP-IN9 SLI + Q9400 + BIOS16 = wrong CPU temp + noisy fan

I notice that the solution from myself was posted as a comment. This may prevent some from locating it. I reposted as a solution under a different name. Hopefully it would help those have the similar problem.

In addition to the following solution, you may also set the CPU core voltage to your CPU specification. My Q9400 VCore specification is 0.85~1.3625V. The BIOS auto setting sets it at 1.1625V. I just manually set it to 1.3625. CPUZ shows that C1E and stepping will lower it as necessary. It should provide the CPU more juice when it needs it, while keeps it cool when it is idle.

Ok, this is myself (Recnelis). I may find the solution for this problem. The trick is to use the beta BIOS 18 and increase the "CPU VTT Voltage" in the BIOS "SoftMenu Setup".

The beta BIOS 18 could be found here:

To make the long story short, BIOS 16 is relatively stable for Q9400 but could not recognize the CPU correctly. BIOS 18 (beta) can recognize the CPU correctly but is very unstable - random application crashes, blue screen, freeze, etc.

Here is some "history" about the issue. Fatal1ty FP-in9 SLI uses nVidia 650i SLI. If you google "nVidia 650i 45nm quad core", you will find a lot of people has the similar issue. Many websites suggest that it is because of the difference between the release version of the Intel 45nm quad core and the one sent to nVidia for testing (due to that nVidia turned off Intel's request for acquiring its SLI technology according to some rumors). Some forums suggest voltage is among those differences.

In the BIOS, you may notice that the voltage settings in the "SoftMenu Setup" are different from the actual voltages in the "PC Health Status". In my case, the actual voltages are similar but lower than the settings. One exception is the "CPU VTT Voltage". The BIOS automatically set it at 1.2V, while the actual voltage in the "PC Health Status" shows it is only a little above 1.0V. That is more than 16% drop. 1.0V is too low to keep the system stable. Guys in o/c world usualy increase the "CPU VTT Voltage" up to 1.5V to keep the system stable. Since I'm not o/c'ing my system, I do not go that far. For my particular case, when I set it to 1.31V in the "SoftMenu Setup", the actual voltage in the "PC Health Status" is 1.2V, which is what the auto setting trys to do. For your system, you may want to increase the setting one notch at a time to safely increase the actual voltage reading.

Before this tweak, my system cannot even run more than 30 minutes under BIOS 18. After this small tweak (under BIOS 18), my system becomes a whole lot more stable (no crash so far after a few days of using). It passed RealTemp torture test (using Prim95) many many times without a single hiccup. I tried to post this at least one week after the system runs in stable status; but I think some of you may still be searching for the solution.

More good news for those who want to keep the Fatal1ty IN-FP9 SLI/Q9400 for a while: I even installed Windows 7 RC (build 7100) with the new nVidia Windows 7 mobo driver and graphic driver. Everything is running smoothly so far.

Good luck to your tweaking.

System temperature too high

Do you still have your manual? If not download it from Gigabyte at this link:
Enter your bios & open manual to page 51, "PC Health Status". Here you can monitor the CPU temp, system temp & CPU fan speed. Notice the manual shows the example of system temp to be 30degs C & current CPU Temperature is at 47degs C. One would think these temps are reasonable. My CPU fan runs between 3308Rpm & 3341Rpm. CPU @ 41deg C & MB @ 31deg C. AMD 64 X2 Dual Core 4200+ 2.21 GHz.
Suggest you try this. If your running Win XP. Open system properties. Click the Advanced tab. Click the settings button under
Startup and Recovery. Remove the check mark to the left of, Automatically restart. Windows should provide an error message if & when the system freezes. This will help in finding what is causing the system to freeze. If your CPU fan is running under 3000Rpm you might consider buying a faster fan or add a case fan to the side of the case to help bring in fresh air to blow onto the CPU fan & PCI-Express card. Here is a decent lace to look for case fans:

Good luck!

Ga-m61sme-s2l motherboard always shut down within 5mins

It sounds as if the motherboard is having a temperature safety shutdown. This occurs when the temperature of the CPU exceeds a certain limit.

First off: Please check your CPU fan, power supply fan, and graphics card fan(if you have a gfx card) that they are working. If not, I would highly recommend replacing the fans or at least cleaning them and attempting to get them started by rotating them manually.

Please enter your BIOS (See Here for instructions) and navigate to "PC Health Status" - check the entry for the CPU temperature. While in the BIOS there is little strain on the system, but if the temperature is above 40 degrees Celsius in this state it may be prudent to check the fan setting. Also, check if there is a CPU Fan fail warning/CPU warning temperature - on average the limit should not exceed 60-65 degrees Celsius, max. Set any Fan speed or mode settings to maximum if able.

Try again.

If problem persists, and you are sure the temperature is not too high and/or the CPU fan is working, it may be the power supply itself. It is possible for the power supply to shut itself off in extreme cases such as when a power supply's fan stops working, and the temperature of the power supply rises to an unsafe level. Sometimes the fan will work initially but quit after a certain time. The fan requires replacement if this is the case.

Let the computer sit for a while and check to make sure it is at or near room temperature. Attempt to restart the installation process. When the power is cut, feel where the power supply meets the case to check whether or not it is particularly hot.

Replacement of the power supply's fan should solve that problem. I recommend taking it to a repair shop.

If that is not the problem, a last resort is that the harddrive is overheating and causing a system crash. With the case open, start the computer (mindful to be careful and always touch a large metal object such as the computer case itself before getting your hands near any components to prevent static damage), and wait for it to crash. Place your hand gently on the harddrive. If it is very warm or hot to the touch, most likely the harddrive's actuator arm, circitry, or data plate is malfunctioning and the drive should either be taken to be repaired or replaced.

If none of the components in your computer are particularly hot, please come back with more information on your computer, such as the parts, what you are cd you are booting, any new hardware, etc.

You have to go into the BIOS setup
and change the Multiplier and bus speed.
If you do only change one at a time and in small Increments rebooting each time
Does your computer do what you want it to do. If so leave it alone as one bad setting in BIOS can stuff your CPU up

Check the CPU temprature from the BIOS. Sometimes if the CPU overheats the system will automatically reboot. High CPU tempratures goes form (60-70). You can also monitor the fan speed and cpu temprature using this utility

Cpu fan starts then stops

Replace it and let us know if it still happens with the new one.It shut down because of overheating, I hope it didnt mess up your CPU.
