Unplug everything inside the computer, except the motherboard and the front panel power on switch. Power up the computer. If the PS fan continues to run, (power supply doesn't shut down)and the CPU fan runs, then power off the unit and reinstall each device, one at a time, turn the power supply on after each device is installed (and off, before installing the next device). You can not easily start the power supply if it is not connected to the cpu motherboard. If the power supply shuts down with only the motherboard attached, then you will need either another power supply, to test the MB, or another MB to test the power supply. R
It could be a Power Supply issue or Hot chip condition on the motherboard due to lack of Air Flow for cooling or a problem with the motherboard. The first things I would check for are a Virus and Air Flow. There are a couple of Viruses out there that will do this. Get a can of compressed air and open the case and clear all the air channels and blow the dust out of it. With the case open turn the computer on and make sure the Cooling fan on the CPU works and the fan in the Power supply is working. If the CPU fan is not working replace it. Same with the the power supply fan, you would have to replace the complete power supply if that one is faulty. If your Video card has a fan on it make sure that is working as well. You maybe able to replace that fan if it's not but you may have to replace the video card if it isn't working. That would present you with a situation that the Video shuts down but the rest of the computer stays running. You will also want to check your power saver options and make sure you don't have them set to shut the computer down on time. I use screen savers and Hibernate settings to protect the screen from burn in but rarely actually shut down my computers.
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.
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). Below is the link for you're motherboard; http://www.abit.com.tw/page/en/motherboard/motherboard_detail.php?pMODEL_NAME=KV7-V&fMTYPE=Socket+A
Hi there. If its the CPU (processor fan) thats not working, it could well be the machine overheating and shutting down to prevent further damage to the machine, try another fan, if it spins up the CPU fan has gone and will need to be replaced. If you have a working fan but it doesn't work on the motherboard, check the power supply unit as that could be faulty.
