No display when power up computer

[acefsj]

Hi I Have an emachine t3642 when i power up the computer i get no error messages or anything it just has no display.
I took out the ram and got an error message so replaced it with new ram and no error.
I can here the fan hard drive everything powers up but no display. My monitor light just blinks.
I even replaced the cpu and still nothing at this point i am thinking mobo.
I also put in a video card and tried using it for the monitor still nothing.
Help please.

how are you getting error msgs if there is no display?
does the display only go out when windows starts to load?
did you try another monitor?

The motherboard is bad. If you really want to spend more money on this, you will have to replace the motherboard and the power supply. The motherboard from eMachines will be expensive, and if you don't get the exact motherboard, you may have to change the CPU and memory types to fit the new 3rd party motherboard

Im getting audio error messages and ya i figured it was the mother board these emachines have a 60% mobo or power supply failure in the first 2 years. Thanks for the help.
