Thanks for your help, i will see what i can find out about the motherboard. Is that likely to be the most probable cause?

Hi, thanks. The monitor is working fine. How would i know if it is the motherboard that is causing the problem? and if it is, is it expensive to fix?

Hi Can anyone help me please? I have a emachines 420 that has died on me! It was working fine and then suddenly the screen went blank and the light around the power button stayed on. The pc had to be turned off at the mains and never came back on! I did notice that the fans werent runnning as i couldnt hear them. I have had a look at the power supply - bestec atx-250-12e 250w power supply and there was no 5 or 12v coming out it and the fan wasnt running. So i ordered another one. When that one came i connected the mains to it and the fan in that one doesnt run either again no output even if i hold the power button on. Is there someway i can test if the psu is faulty or if something else is causing it not to work. I have tried it powered and disconnected from the computer but dont know if it needs to be turned on some how? I dont know if something could be wrong with something else which is causing the psu to appear faulty? Thank you Michelle
