Hello there:
first unplug the computer and open the case
find the power supply cord that goers to the motherboard and remove it now press in the power on button and hold it in for 30 seconds and if you have a reset button do the same for this now reisert the power supply to the motherboard
And since you are in there check to make sure that all of the connections are tight and clean
Now plug in the power cord to the computer and reboot and see if it now works
If not try to remove the video card and reinsert it in a different slot and repeating the steps above and than reboot if still nothing i would suggest that you get a new video card
you can also remove the memory sticks and reinsert them 1 at a time and reboot after each one and see what happens ok?
I hope that this is verry helpfull for you there is still more that we can do if needed ok?
best regards michael
I hope u r a professional in handling viz assembling/disassembling pc(s)..and assuming that the bios has not been flashed in a wrong way..probably itz either a case of loose ram/board short/improper ground/cmos battery..plz do check the following as in order:..

1) see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..

2) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

3)\015\012remove/clean dust neatly..dust is non-uniform in nature n may cause\015\012jam/short circuitry/excess resistace n many more..resulting an increase\015\012in heat..

4) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink\015\012Compound" (available in local electronics chip level spare market)\015\012between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it\015\012tightly in position..

5) the smps itself may b defective/faulty..check the outputs of smps\015\012viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg\015\012& grey~sb); -12v (blue); -5v(white); +3.3v(orange)..
\015\012the 'oscillator and error amplifier ic', or\015\012pwm switching regulator circuit..look for defective\015\012protector-transformer/resistance(esp 4.7k)/mosfet..
\015\012
\015\0126) if\015\012itz not the smps, then it must b ur main/mother board..see with a debug\015\012card for mb error..may b short..look for defective capacitors(esp above\015\0121000mfd)/mosfets..go through the mb's south bridge n the circuit lie\015\012around atx connector....
\015\012
always better to seek advise from ur system admin/vendor....
