To summarize: One day his PC would not turn on. He replaced the power supply. Now when he tries to turn it on it seems to turn on for a split second (for example the rear fan light goes on) but then nothing, And, then the power button on the front of the machine blinks repeatedly, but the PC does not turn on.


Good chance the motherboard is dead.


To troubleshoot you could unplug everything (drives, extra expansion cards etc) and use onboard video (if it has it) so that all you have is Power Supply, Motherboard, cpu, 1 stick of ram. Then make sure that the power supply is correctly plugged in to the motherboard (probably it's what, a 20 or 24 pin plug, plus a 4 pin plug?? I forget) and properly seated. And then see if it works.


As a final resort, you could take the motherboard out of the case, and put it on something like wood or cardboard, and just have the powersupply and the motherboard with the cpu on it, and then use the paper clip trick to turn on the computer (thus eliminating the case power switch as an issue). The cpu fan should spin if the motherboard is ok.

You may also want to check your capacitors (Cylinder shaped items on your motherboard). If any of them a bulging (not flat on top), or are leaking any of the electrolyte fluids (will look like a browny orange crust) out of the top, then your motherboard is dying. This usually occurs from overuse (being left on for a long long long period of time) or by heat. Usually this is typical of Dell computers that have smaller cases with the airflow going directly over the capacitors, but has happened on normal case Dell computers as well.
