I have a HP pavilion p7-1380t. (about 2 years old)
I have tried all suggestions found on the web and none work.
Have tried various boot up programs and they don't work.
When I boot up here is what I see: black screen, mouse only
flashes for a second, "F" keys do nothing, DVD flashes for a
couple of seconds, power seems to be working.

The computer was up to date before this happened.
My guess is the boot program is corrupt.
No matter what I do NOTHING comes up on the screen.
I can't access anything in the computer!
Thanks for any suggestions....
 
Do you see the POST screen at all? Can you get into BIOS?

My first thinking is to try a Live Linux CD to see if that does anything.
 
Thank you for replying Eulogy.
I don't know what a "post" screen is but my monitor is
black if that is what you mean.
I can not get into BIOS or anything else.
I do not use Linux.
 
Try to boot it with a linux boot cd. If no image still comes, check your monitor cables. They may APPEAR to be in place but are really not. Verify the cables are correctly in place by pushing them in again at the monitor side and computer side.

Also check that your monitor is plugged in the power and on. Seriously. Also if you unplug your monitor from the computer and turn it on you should get an error message display. If your monitor just stays blank you have a broken monitor.

If erorrs show but no computer image comes, you have a defect graphics card or worse.
 
Looks like "Easy Recovery Essentials" by Neosmart might do the job.
Only problem is it's a tad pricy to use just once - $20. AND I am not
absolutely sure it will fix my computer.
 
If it was a boot issue usually it'll give you a sign that something is corrupt/missing. If you can't get anywhere upon a reboot and it sounds like Windows is still loading in the background, then I would think it has something to do with the monitor or graphics processor.

Since you're seeing nothing but black on a restart it isn't really hinting to anything specific. Does the mobo make a beep sound? If it makes just one that's usually an all clear sign and Windows is loading.

One of the hardest problems to diagnose straight away is the monitor backlight burning out. Everything seems to work fine and dandy but you get no image whatsoever. That's why it's essential to remove the DVI/VGA connector and see if the monitor displays a 'no connecion' error. If nothing still shows the monitor is very likely to be broken.

Start simple... I would start by swapping monitors with a known working monitor, then I would swap with a temporary known working GPU..
 
Thanks guys for helping.
I swapped monitors and it made no difference.
The computer beeps continuously until I hit F1.
I have taken the battery out for a couple of minutes
and it made no difference. I also went out and bought a
new battery and that made no difference.
At this point I am uncertain if it is a hardware or the
MBR that is corrupt. Since I can not gain entrance to
the computer, I have no way to fix a corrupt MBR.

That's not normal at all. Have you tried counting the beeps? They are all supposed to mean something very specific including whether it's a short or long beep. If it's more than one then you can take that and google the MOBO manufacturers beep codes to figure out what piece of hardware is causing the issue.

If it's an endless cycle of beeps then you probably have a faulty keyboard/stuck key. Not sure if those would completely cause this issue, but it wouldn't be normal regardless.
 
Solid tone? Not a quick "beep"? I'd check CPU fan, then CPU itself.
 
Not a sold tone. A never ending series of short beeps.

One of piece of information that might help:
I use Clonezilla-live to back up my HD. It starts cold and boots
into Clonezilla-Live. Clonezille-live will not boot on this computer.
Fans are working. Don't have the vaguest how to check the CPU.

Even if the MBR is corrupt you will get a display of an error message.
Try to boot from a linux cd as others have suggested, at least you should get something to display.
Do you have an add in video card or built into the motherboard?
 
If I have an add in video card, HP put it in the computer
when I bought it.
I tried to get a Linux boot cd but they all seemed to
come with an OS, which I don't want to mess up whatever
is left on my HD.
How can I get a Linux boot cd?

Describe your beeps in more detail. You do understand that the length and pattern of beeps will tell you exactly what's wrong with the PC, right?

Those are basically Morse code for broken computers. For example, on an HP computer, two short beeps and one long beep means failure to initialize the GPU.

So tell us exactly the pattern of beeps you hear, including any pause in the beeping.

You're given the option of either installing the OS, or booting a live OS when you begin the boot process. Simply select the live option. On some Linux distros, it's called "try Linux" or something similar.

If you cannot enter BIOS though (as you stated before), you may not be able to boot from a CD or USB. Most - but not all - motherboards will, after boot failure, scan available storage devices, look for a bootable volume and then present you with a selection screen or automatically select the volume itself. Perhaps you can get a live OS going that way.

The beeps are about 1 second long and 1 beep about
every other second. Yes I understand.

I tried PcLinuxOS and nothing happened. The DVD blinked
a few times and stopped.
Thank you.

I guess I am confused with this comment. So you are able to access the clonezilla live media or not?
Have you tried swapping the RAM with known working RAM?
 
Clonezilla-live will NOT work on the computer that I can't boot into.
I have no ram that I can test on the failed computer.

If you have two DIMMS (which you should) just take them out one at a time to test them both. At this point it could be a faulty monitor, GPU, or MOBO all of which are going to be a pain in the ass to troubleshoot if you don't have extra parts or someone who does.

I would say it's 100% hardware and the only problem is finding out which piece. The best you can do is only have the bare essentials plugged in. Double check all connections from cable to device or device/cable to motherboard and look for burned marks. If nothing else I'd probably just get it taken in because otherwise you're going to be playing a guessing game without parts to test.
 
Check your motherboard support pages and check what 'one continuous long beep' means as an error code. In many cases one long beep is indicative of some major problem such as bad CPU or bad ram.
 
Pardon me. I have two computers giving me trouble and I gave wrong information
for the HP. There is NO beep at all on the HP. I also tried another keyboard and
there was no change that I could see. I tried cntr/alt/delete and this did not shut
off the computer. I am plugging the keyboard and mouse in the back connections.
 
Guess I'm going to have to junk the computer. If you guys are stumped
then I don't have a prayer of fixing it.

Did you try another monitor already? If yes and you know the monitor is working, try removing every part from your motherboard except the cpu and cooler from the motherboard and put them back one by one. Even the power cable, unplug it and replug it to make sure it's tightly in place in the motherboard.

First try plug on only the graphics card and 1 memory stick + DVD drive. Then try booting a linux live dvd. If your computer doesnt boot, replace the memory stick and try with the other one, try again.

If your computer still doesnt boot, try another power supply. Then try another graphics card if possible. If still no boot or even post image THEN consider dumping the motherboard but you can still reuse most components.
 
I tried another monitor and nothing.
I tried the "systemrecovercd" and it did nothing.
I tried a "Knoppix live cd" and it did nothing.
My knowledge of the connections of a MB is zero.
I can pull items from the MB but I would have no
idea what I am pulling.
The MB is a h-Joshua-h61-uatx from HP.
This is the original MB from HP.
The computer is a Hp Pavilion p7-1380t
