Question about E-Machines C1641 PC Desktop
So turning on the computer doesn't bring the monitor out of standby? Just to be sure, try turning the monitor off, then on again and the Pc on at the same time. If you see any writing on the screen, that will be good news. Make sure it isn't just the cable to the monitor. It is possible to mess up the connector on the cable where it goes into the computer. If one of the pins is bent, use tweezers, to very carefully try to bend it back. If it breaks you have a big problem - have to find another one and splice it onto the cable or replace the whole cord. Still nothing on the screen. Could be the monitor. Could be the video card, the motherboard, the microprocessor or the power supply. The worst case is that the old power supply failed drastically and destroyed all of the above. Try your monitor on another computer. Any sounds coming from the computer when it starts? Startup music would be a very good sign - most everything working. Any beeps? Three beeps mean the video card has failed but the motherboard and processor are probably okay. I can't think of an easy way for you to test the motherboard and processor. If you have access to a similar computer, you could try swapping in a known to be good video card. It sure looks like the worst case scenario.

Tips for a great answer:
remove all the ram from motherboard and switch on the system and see it is working or not like just on and fan are rotating and the smps fan is also working and your system is giving beep sound for ram.try with other smps also some time problem with power supply also. Remove the connector of power switch and restart switch and directly try to on from shorting the connector with the help of pen or screw driver point. Some time faulty switch also give problem. Just try all these possibilities.
