I have recently changed the power supply as the previous one was shot. So it ran for about a day fine and then afterwards if I turn on the power, power supply fan turns on and colling fan on top of the processor for a brief second and then turns off automatically. What you think problem could be?
Your help in this reagrds will be greatly appreciated ...

Re: power turns on and off
Sounds like a thermal issue. New power supply might be overheating the cpu causing the thermal sensor in the cpu to automatically shut down so the cpu doesn't fry. You could try adding a case fan or two plus upgrading the spu heatsink/fan. Hope this helps.

One bad lead will cause your computer to shut down or continue in a cycle replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to your hard drive hope this helps
bad leads try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive they probably be faulty hope this helps good luck
If all you get is a green light, and no fans, hard drive spin up, nothing on the monitor, well than, it could be that the power supply is the wrong one for your computer. Either that or the motherboard is shot.
double check on the power supply, that is probably the problem.
try installing a chassis fan to reduce heat inside your case, as the other guy said, dust is a big possibility, the problem does not appear to be CPU but I would check to see that the spu fan is running normally.
Another thing could be that it is time for a more potential power supply.
what kind of computer is it? how old is it? have you added, removed or changed hardware recently? have there been any power spikes, outages or surges lately while the computer was running? lastly are the voltage settings 120V/240V on the power supply set correctly? it sounds like the power supply is dead from what i've read but i can't be sure because there are many reasons this could be happening, i.e. the processor gets too hot while the system is trying to start and the computer shuts down to prevent damage to it, also have you tried plugin the system into another wall outlet or socket on your power strip? if no hardware has been add, removed or changed. you can start with a power supply but if after that it still won't power up there's a deeper cause to look for!
Remove you CPU Heatsink and fan, look around the socket for possible capacitor damage. look at the small brown ones if the top shinny surface is poped up like in this illustration. If so then replace you motherboard
