Why Won't My Hp Desktop Computer Start Up?

Postby Xalbador » Sun Oct 08, 2017 6:02 pm

When I attempt to start up my HP Pavilion desktop computer, instead of fully booting up and bringing me to my desktop, it gives me a blue screen with the HP logo. It has a few white words at the bottom (i.e., , ), but when I attempt to do any of these options the computer remains unresponsive on thesame blue screen. What is happening, and how can I fix it? And if I can't fix it completely, how can I retrieve my files? I last backed up my files 3 weeks ago, but there are plenty of important documents I'd really like to recover.

Someone, please help...

Why Won't My Hp Desktop Computer Start Up?

There are many things that could have gone wrong with your computer.
You can try hitting ESC repeatedly while the computer is first starting up to see if you can get into the bios.
If you can, then the first thing to do is to disable that HP logo screen - you should be able to do that somewhere in the bios.
If ESC does not work, then try DEL.

You can get back most, if not all, of your data by removing the hard drive and putting it into another computer, where you can copy stuff over to the other computer and save to cd's or dvd's.

You may need professional help, but if you want to try to fix this yourself, hear is a brief description of my technique:

If your computer won?t even boot to the bios screen, then the first thing that you should do is turn it off and pull the plug or, at least, turn off the power supply on the back of the computer.
Let it sit for an hour or more and try again.
If this cures the problem, then when you?re finished for the day and shut down, always turn off the power before you leave.

Check to make sure all the cables, inside and out, are seated properly and haven?t come loose.
Don?t touch anything inside other than the cables. Remember to have the power off while you are working inside the computer.
Unplug it from the wall.

If these don?t work, then you probably have a bad piece of hardware.
You try to isolate this bad piece by disconnecting all the peripheral hardware and then boot up, adding pieces one by one.
(Turn off the computer and unplug it while you are adding each piece.)

For the first test, you?ll be listening for the error code beeps, so if your motherboard doesn?t have a beeper or buzzer, you?ll need to hook up a sound device.
Use the minimal amount of hardware necessary.
If you have an error code LED to give you diagnostic codes, then that is even better, because you don?t need sound.

Start with only the motherboard, power supply, cpu, and cpu fan connected.
Turn it on and see if you can get error code beeps.
You should get error code beeps for missing memory and/or beeps for a missing video card.
(This is why you need some kind of sound player, since your mb might not have a beeper.
It?s better to not have to connect any audio hardware, because that?s just one more complication.) If you hear the beeps, and if your manual gives the meaning of the beeps as missing video card or memory, then you can relax as the core of the computer is solid.

Some power supplies won?t work without a loadon them, so if the basic test above doesn?t work, then repeat it with the hard disk drive connected to the power supply, but with the data cable not connected.

If you don't get any beeps, then you probably have a bad motherboard, power supply, or cpu. If the fans start and run, then you can continue on with the other tests, hoping that there is just something wrong with the beeper - if you?re not using the mb beeper, then disconnect the audio devices as they are no longer needed.

At this point you now start adding things one by one, looking for the faulty device. First, add the video card, remembering to connect any video power connector, and see if you get video. Add one stick of memory. You should get video for sure now - the bios screen. If not, then use a different stick of memory, one at a time. If one stick works and another does not, then you?ve found the culprit. If you still don?t get video, it?s probably a problem with your video card. To work properly, video cards usually need special drivers loaded, but they should still do the basics without any drivers.

So, if you?ve reached the point that you can see the bios screen, then you add pieces one by one until you find the piece that causes trouble. First, connect the hard drive, then the sound card, then the optical drive(s), modem, external drive, etc. When the computer won't go, then the last piece added is where the problem lies.

seems like something is wrong with your bios if you can't even go into its settings, the hard drive should be safe so you can remove the hard drive and put it on another computer to retrieve the files.

I'm assuming you are on a working computer now. hopefully it has a floppy drive and the same operating system you are using now. if not, find another one that is. do a search on the machine that's working, find the shell32.dll file and copy it onto a floppy. go to your HP, boot it up hit f8 and choose safe mode, command prompt only. copy the file to the Hp putting the floppy in, type a: then type copy shell32.dll c:\windows\system32 my guess is what has probably happened is a spyware or antivirus quaruntined the file so now windows can't find it, it needs it to boot. give this a try before you reinstall and lose your data.
