It seems like a motherboard issue. It heats up, thus is not able to turn on continuously. You may need to check internal parts embeded on the motherboard llike the fan and processor before you could know what needs replacement.
chek your power unit or the cpu fan working or not if the cpu fan is not working computer will turnoff immediate to save it you better show you computer for technician soon
please rate this solution.....
what u may have done is wwhen u were installing the new board, gave a static shock to the system...that will cause only the fans to come on and nothing more...this is a bad problem bc u cannot fix it...if u figure out something else is wrong, and it gets fixed, let me know
1.) If when hitting the power button, ABSOLUTELY nothing happens, no fans come on, nothing- You need a new power supply most likely. I see this all the time in my shop. Here's the bad news- Dell likes to use their own special power supplies, so a normal one may not even fit in the case. If that is the case, then I'm sorry to say Dell likes to charge over $100 easily for a new one.
2.) Fans come on, lights come on, but no screen. This can mean any number of things. Bad VGA cable (or DVI), bad RAM, bad mobo, even a bad PCI card. time to start troubleshooting. Change what parts you can, remove any PCI cards that are not needed, remove one RAM card then the other, etc....
If the noise is constant then it means the problem is either:
1: a Power supply issue 2: a motherboard issue 3: a keyboard problem
the latter of the three being the easiest to fix, try booting with your keyboard unplugged or even better if you have another keyboard try using it to see if that corrects the problem.
If the above does not work then you have a problem with 1 or 2, and in order to find out for certain you will need to test it, you can goto your local computer diagnostic store to see if they can check which it is.
Mostly your heatsink damaged your motherboaard. check caps lock LED and Number Lock LED are working after switching on. If not ur motherboard or processor get damaged and u had mentioned what happened. Ur heatsink shorts some circuit in your motherboard
Just to check the voltages coming from the psu. However if your old psu is doing the same it must be something else. Did you try it without the graphics card? and is it the fan in teh psu which is spinning up?
My next port of call would be any other expansion cards, followed by the memory modules. Take them all out apart from one memory module and try to boot.
Also check that the pins from the power button are connected correctly. you can also try starting the pc by touching the two pins together with a metal tipped screw driver.
There are a wide range of possibilties. first if nothing at all happens when you press the power button. (no lights no sounds etc.) then the most obvious culprit would be a dead power supply or a switch in the back thats off.
Are there any fans or lights?
Please let me know...
