I have bought recently a motherboard and and after I installed all components on it, and powered on, nothing happened. No beep, No display. I examined that CPU was cold as there is no sign of power in it. Also whenever I power on the board with CPU installed, PSU starts randomly on and off automatically, and when I power on only motherboard without CPU, the PSU works fine (i.e no on off). Any idea what is the problem?? Is the motherboard or CPU dead..
P.S. I have checked each and every possible thing like jumper settings, change PSU, RAM etc.. but not CPU as I have only the one.
But it couldn't be as I have changed 3 PSU, and all are working on other motherboards. I think that my motherboard was defective right from manufactures (DOA). Anyway thanks for your answer..

What you can do is to reseat all cables that are connected to the CPU. Also, try reseating all components connected to the motherboard. that includes the RAM, Video Card, etc. Here's the proper way to reseat them.
First, remove everything from the motherboard then install them one by one. Once you installed something, try to boot it up. until you have isolated the cause of the problem. The most common cause of this kind of issue is the memory(RAM).
That's what you need to do before you throw your desktop away.
If you are getting no post code and it wont boot, that means that one of your core components has something wrong with it ( main components are: motherboard, ram, CPU and fan, or power supply. ). This could be something as simple as a loose connection or a connection that was not plugged in (like the motherboard 20 or 24 wire connector, the CPU 4 wire power connect, etc). This could also mean that one of those main components is not supported by the rest of the system, or one of your main components has gone bad. Usually if its a component gone bad or not supported it would make a series of beeps instead of the one beep post code. Go through all your connections and make sure they are all in place, and on the right place. Make sure thats nothing is improperly grounded. Make sure that your ram is all the way in.
If your PC is still booting like normal even though it does not have a bios code beep, then this can be problems with your case speaker connection or the speaker it self. Sometimes disconnection the components that are not main components and and trying to boot like so might give you a better Idea as to what might be happening. If you have recently added a new component this could be that the power supply cant handle to power up everything (not enough power) so it wont sent the 'power ok' signal to the motherboard and the motherboard in this case will not boot.
Good luck. I hope this helps in some way!!
it sounds like the hardrive you installed overloaded the system and cause a low power operation on the computer the motherboard may be bad because of this as well as anyparts that were connected to it i have had this happen to me before and well i know it sucks but your best bet is to just buy a new computer and make sure you power supply can handle extra parts...
Unfortunately, you can't solve this problem. What I have learned as the tech working on a customers gateway mt6451 is that Gateway dropped the ball when they bought a cheap (they spent 5 cents instead of 20 cents) motherboard component that allows the adapter to charge battery and run the notebook without the battery installed, the component seems to have a 1 year if that life. I am surprised they haven't been sued or forced to extend the warranty (like HP had to with their dv8000 series notebooks) althought they would have to replace the motherboard with one that has an improved component on it. How do you sue a company or force them to extend the warranty for a replacement that is made with a better component?
are all the wires connected correctly? if it is, then try to see what is incorrect connection on your motherboard it must be the RAM(memory) or the processor. see also the connection between the monitor to the computer. if it still not working then try to remove the memory and then switch it on without it. you will hear a sound, if you dont then your memory is the problem.also see if the video card are correctly connected too. hope that helps!
Have you recently experienced a power surge or had an electrical (thunder) storm in your area? Potentially your motherboard and/or processor could be toast since the fan running and CD Rom drive opening will continue to function because they receive power separately from the motherboard via the power supply. If you have access to a different compatible processor, you could try to install it in the motherboard to rule out a motherboard failure, otherwise you're looking for a new motherboard.
PSU or CPU??
But it couldn't be as I have changed 3 PSU, and all are working on other motherboards. I think that my motherboard was defective right from manufactures (DOA). Anyway thanks for your answer..
