Powers on for a second and shuts down

#1 on the list for this is shut down from over heat due to CPU fan not running or CPU overheat. Check to see if your CPU fan is turning on when your system is powering up. If its not.. thats your problem (get a new fan)... Even if it is it could mean the fan is not properly contacting the CPU with thermal paste. If this is the first time you\'ve powered the system up, your next step is to go out and get some thermal paste and put it under the CPU fan, if you\'ve been running the system and this problem just cropped up.. skip the thermal paste, its already there. #2 Next possibility is BIOs power settings are incompatible with your hardware. For example the frequency on the CPU is set higher then it can operate and its over heating. Some systems will automatically shut down and restart with default settings others you have to get into and set to default. can you get into BIOS? Can you reset your BIOS settings to defaults? Check your mother board manual. #3 A compenent is shorting out your system and needs to be replaced. Is the system posting prior to shutdown (beeping once on start up?) If its beeping more then once that means something else and you should read your manual. If its not beeping then its a short somewhere and you can bet you have a bad part in the system. To identify which part it is you can either disconnect things (RAM, Drives, vid card, PCI cards,ect) one at a time, attempting to start the system after each one or you can take everything but the bare bones out and try to start it. I usually take all the RAM out but one stick and start by testing them. Your RAM is the most likely place for a problem in this situation. #4 If you\'ve striped it down and it still can\'t get a boot (with no post beep). You need to replace the mother board.

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

usually this means that the board is powered on, but that the cpu hasn't been initialized. make sure your cpu pins are clean of thermal grease and that it is properly seated. make sure your board is compatible with the cpu and if you can get a spare (known good) cpu to boot the board with, see if it starts, and see if you can update the bios.

again, basically the issue is CPU related. at some point you may have to just RMA the processor since it is a possibility that it might be DOA. good luck!

Gd morning

O.k are you building a new system...the memory you are using is it the original memory,if so try a new stick or try it in a different bank..
Is the memory compatable with the motherboard i.e the memory you should be using is DDR...
how big is the memory...

Hope this help....please rate this as i,ve taken the time and trouble to help...if i can be any more help..

yes you can! compatible motherboards are cheap and easy to find for the socket 754 design compatible with your cpu. with prices going from anywhere from ~$50-$80. great places to shop include frys electronics, newegg.com, amazon.com and tigerdirect.com. when something like this happens to you its always a good idea to consider upgrading your computer as well you can find cpu motherboard deals anywhere from $100 to $200 with a huge boost in computing power. if you choose to go this route make sure your ram will work on the motherboard you are considering. goodluck

no, this board is only compatible with AMD Opteron 1000 Series AM2/AM3 Cpu's. This board is designed for a server environment, hence the use of the Opteron CPU which is primarily used for server systems. Your CPU is an Athlon series which is mainly for home/business use and will not work with this board.

Probably shut down by thermal protection settings in the BIOS; either fan is insufficient or something wrong with board/CPU; if the problem existed across 2 boards, I'd have to expect you have a fried CPU. Get a used replacement at RePC.com (so you don't have a big $ investment in troubleshooting.) Alternatively suspect failed HD (boot from a CD or floppy, esp useful diagnostically if you can disconnect the drive). Here in Seattle "Seattle Laptop Recyclers" (or some variation on that name - Aurora Ave N.) will diagnose and repair for $35 plus parts... it might be cheapest to ship it to them. Not a laptop? RePC repair service is very reasonable (I don't work for either company.)

looking at this old motherboard the 2400 is unlikely to work, the motherboard has a cpu fsb support of 133mhz and supports the duron processors.

offhand, 2400 wont work.

RAM can be finicky so first test all memory slots with a known good stick (your 512MB). Make sure you're starting from a complete power down and you get a POST beep (hopefully your system is set up to beep when it powers on) and everything loads up all the way through to your OS.

Once you do that with all your memory slots test with the new stick by itself in all memory slots. If neither of the memory slots work with the new stick but you verify that it works in another system you should then check your BIOS settings and RAM timings to ensure compatibility with your stick. If you can't find the timing on the RAM stick itself, look up the manufacturer's part number for the information.

Good luck!
