Having problems with your eMachines T6420 PC Desktop ?

Fan comes on but monitor says no signal the screen stays black and the fan keeps running won't turn off by button have to unplug it for it to go off


Answers :

I assume you are hearing the power supply and maybe the CPU fan. If you can see what you are doing, then I wouldn't expect you to be able to turn off the computer any other way than doing a hard shutdown.
I would not have bought a new monitor, you were see a display that said no signal, you should have believed it, because that is your problem you have no video signal. If it sounds like your computer is booting up properly you have a bad video card, a bad video cable or both. I would first turn off the computer , disconnect it from the outlet, open it up and try re-seating the video card. You can also try a new video cable, if none of this works I would then install a new video card.
Not sure if you want to go to all this time or expense, but that is the route to go for a DIY project, either that or being it to someone who has the tools and skills to figure it out for you. But I definitely don't think your monitor is the problem
You need to replace the fan, it will cause further damage if you don't.
