It seens like a motherboard or power supply problem.

If you have a spare PSU, replace it with the current computers PSU. If you don't have a spare, you can always take one from another computer.

If the problem is still showing up, then the motherboard may be defect and will have to be replaced.

Cpu high temperature, cpu shutting down


The CPU is shutting down because it is overheating (ie thermal shutdown) and won't boot up again until it has cooled down. If this problem is not fixed, eventually the CPU will fail completely.
Check the CPU fan to see if it spins freely. Also check the power supply fan to see if it spins freely. If the CPU fan has failed, then replace the CPU fan. The CPU fan and heat-sink assembly may be clogged with dust, if so loosen the dust and vacuum to remove the dust.

My computer shuts down after a few minutes


2 possible issues come to mind: 1) the computer is getting hot (CPU, memory or video card), 2) the power supply can't keep up with the demand.

Try using a program that lets your track your computer's internal temperature. System Information for Windows, http://www.gtopala.com/ , is the one I use. Depending on the cause, you may need to increase the ventilation of your case (add fans - slot cooler by the video card, front, back or side panel.). If the CPU is getting hot, make sure that the CPU cooler is working and consider removing it and reapplying a new layer of thermal paste before reattaching the cooler.

If the problem is the power supply, check the specs on your devices (memory, CPU, video card) and the power supply load rating. You may need to upgrade the power supply.

I hope this helps.

(I am not a gamer but the default power supply that came with my computer didn't have enough power for the added memory and video card. I replaced that and added a back fan (spot available), a slot cooler, a drive bay fan and cut a hole to add a side panel fan.)

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


soks3d,
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;
http://www.directron.com/a4004d.html
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).

The ASUS monitoring system for the motherboard is reporting that the cpu fan is inoperable and that is shutting down my computer


Try to replace your CPU Fan. And also check your power supply if it still supplies the correct voltage your motherboard needs.

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.
