Hi.... My friend ha I3 porcessor with Intel motherboard and Umax 450W processor, all are new...
When we put together and test it out of the cabinet in a wodden table, the processor fan starts and stops after 4 or 5 secs and then starts and stops after 4 or 5 secs. It is doing repeatedly...
During this there is no sound (beep) from the motherboard and there is no display..
We also checked with two sticks of ram, one stick of ram, without ram, bios in recovery mode, reset mode, removing cmos battery.. Nothing works..
If any one knows, please let me know....
From the problems that you are describing, the problem that you are experiencing is a no POST problem.
It seems like you covered most the troubleshooting steps that could be performed.
At this point I recomemnd you to start testing with different parts like another processor or your processor on another compatible motherboard to determine which one is the culprit.
