Can you hear a beep code when you start it? Can you hear if the fan is running? Check connection to monitor.

Is it a pc or laptop? If a laptop I think it's FN + F4 to change screen outputs.
But if a pc then beep codes will tell you about problems most of the time. If the computer was moved I have saw the memory chips shift enough to cause the beeps and not boot. If the computer is indeed booting up and not showing display, you should be able to turn it off after letting it sit on for a while by pressing the power button. If it shuts down it's probably working but if it does nothing the computer isn't booting. Just press the power after a few minutes and not hold it in to see because holding it in will force it to boot and tell you nothing

Hi Ramon, thanks for your answer.

I Can't hear de BEEP, But The Motherboard fan is running, and the power supply fan is running too.

Thanks.

can you see the boot screen the boot sceen? what happen to the pc for it to stop working? was anything replayed? or it just stop booting up? if it you get the boot screen and then the blue screen of death then you probly have a virus of spyware and should reinstall your operating system

Hi,
I can't see the boot screen, not bios screen too, it just stop booting up.
The screen is fully black, look like getting no signal from CPU.........
Some Bad hardware maybe.
Thank you.

If it just stoped booting all the way it might be the power supply, happened to me once before were it starting booting but never went past that. Otherwise has there been any hardware changes?

With the power off, press and hold F5 and then power on. Don't release F5 until you see a pic. Worked great for my laptop.

Could be the RAM.If a RAM chip is bad it can cause a computer to try and boot but as a result you get just the black screen.Most of the time a beep code but stranger things have happened.
Could also be a bad video card,sound card.Have seen this in many years working on computers.Usually get beep code for most problems but some brands you never know.

Try a different monitor to see if that works.

It could also be that the on board video chip or video card is at fault, there is a class action lawsuit against Nvidia, who supplies the video chips and video cards for HP (and others) who makes Compact PC's, read this and see if you can get it fixed for free.(if your PC has one of these chips or cards)

I had this same thing a few weeks back and it turned out to be the video card. Got a new one for $15.00 and works fine now.
Good luck..................

mostlikely it is the video card.if it is a built-in video card you can not fix it.if it is a agp,pci,pci-e video card try to take out the card and try to clean it out.many times dust build up inside will make the gpu of the video card stop working.try that if it dosent work best thing to do is buy another video card.very cheap now days.good luck

Well, I have lost video cards and power supplies with the symptoms listed by the op. This is why I would turn it on and allow it to run for @ 5 minutes. After that time just push the power button, if it's just the video card you'll hear the hard-drive dumping and then the computer will actually turn off. Most computers will boot without a video card- and the ones that don't will usually beep at ya telling you somethings wrong.
