Computer does not start after the screen goes blank & Compaq.

Hello

A few weeks ago, I turned on my PC and it showed at the Compaq screen and then went to a blank screen & would not respond. I held the switch button to turn it off and after 4 attempts, it start fine. Next time, it took 20 attempts to initialize and now it does not start, it will be maybe if I try like 100 times he can do... The problem is when the Compaq screen comes up it comes only for like a second so I know that it does not start, if the Compaq screen stays for a few seconds as 3 + I know it will load windows and start.

History > the computer originally had XP and has been replaced with VISTA memory was 2 * 512MB, but it was a bit slow and I was advised to upgrade. I bought 2 * 1 GB memory and put it in my PC a few months there may be 5 + had no problem so far.

I tried the following:

Remove the memory and replace it. Remove the 2 * 1 GB of memory and its replacement by the Moose 2 * 512MB to check if the memory is at fault.

Cleaning of the dust around the fan (at this point, I removed the fan over the CPU and cleaned the thermal compound from the CPU to make it nice and shiny, only tried to start one time after that for a few seconds heard blowing fan and turend it took off. Depuis_lors, I realized that it wasn't just muck and had a purpose na derwiche put a little more on)

Remove the battery of the BIOS for half a day

Move jumpers CMOS from1, 2 to 2, 3 positions

I can not get into the same if BIOS start and hold F1 he will show me the BIOS for a second and then go to a black screen.

Specifications of the computer

I gave my pc to somone to look to the he tried not to turn on he opened it removed cleaning my thermal paste back on and told me it was working fine.

When I bought home all happy, I realized that I had the same problem, I borrowed another monitor and found it worked well! So the question is with my monitor, if anyone has the same problem first check another monitor.

  • Computer does not start after the screen of the bios, Compaq Presario SR1023WM

    Ok. Trying to fix a friend's computer and seem to have met a strange barrier.

    Problem: The computer does not start after the bios screen.

    Details: When you turn on the computer, the compaq logo with intel inside is and has the < F1 Setup > and < F10 System Recovery > options listed as well.  And that's it as far as the computer becomes.  After that the computer just locked up, no work of buttons on the keyboard lights keyboard ect ect.  I tried the puree on the F1 key, as soon as I turn on the computer and I can handle so he can say * entering setup * but it freezes again after this point.  I already tried to eliminate the possible sources of the problem, removed all expansion cards, HDD and Dvd Rom module only disconnected, only memory (256 MB ddr 2700), power, vga and keyboard connected.  Ive also used the jumper on the motherboard to clear the cmos, hoping that would solve the problem without success.  I tried using a different memory stick and different memory as well...  Tried to use both a ps2 and a usb keyboard... Ive even tried pulling the rider for the protection of the bios password (even if she did not have a password on it, just try everything I can think of).

    The installed bios version is 3.1, and that's all that I know on the computer at this point, except that the website tells me to him.

    I'm basically at a loss on this one, so if someone feels scroll line-by-line of their brains on this one, I'd be very happy.

    I have a pretty strong understanding of computer repair, so feel free to give me something to try.

    If you need more information out of me, let me know as well.

    Try to clear the CMOS again but this time remove CMOS battery and hold the power button on a few seconds. Replace the battery, then try to start back to the top.

    1. computer does not start after the Windows XP logo window
    2 works well in safe mode, even connect to the external monitor
    3. I reinstalled xp many times, problem stil exist.

    All the answers?

    Hi dhanushm,

    1. What happens after the Windows logo screen?
    2. You receive an error message?
    3. You have security software installed on the computer?
    4. Have you performed an installation clean Windows XP and even after that this problem exists?

    Method 1

    As the computer starts up fine in safe mode there is a possibility that some third-party programs installed on the computer is the origin of the problem.

    I suggest that you configure the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See section to learn more about how to clean boot.

  • Satellite Pro L300-21F does not start and the screen remains blank

    L300-21F is aged 18 months, so out of warranty. When you press the power button, you can hear the fan and a "click" but the hard drive does not start and the screen remains blank. The power and the battery on the headlight LEDs, but the switch light does not work. I checked the power supply and it is 19.3V and substituted a good known. Removed the battery, tried with just the power cord and still nothing. Pressing ESC or F2 when you press the button power does not bring to the top of the screen of the bios or any other message. I have concluded there is no power the jury. A friend he had its technology take a look and he concluded Council is probably a friend.

    So my questions are:
    1. He's probably right?
    2. is it a common problem with an easy solution?
    3. what else can do before shelling out for a new Board of Directors?
    4. is there a link where I can find how to disassemble the case?

    Any help appreciated

    Hello

    > 1. He's probably right?

    Yes, it looks like motherboard failure

    > 2. Is this a common problem with an easy solution?

    If it's a motherboard problem, the whole motherboard is replaced. Quite expensive part...

    > 3. What else can do before shelling out for a new Board of Directors?

    I don't think you can do anything with fried mobo

    > 4. Is there a link where I can find how to disassemble the case?

  • You can save a broken computer? My computer does NOT start after the blue hp screen.

    In the past months, my computer has been the object of a freezing randomly, and Ctrl + Alt + Delete does not work. I stopped him via the power button. Sometimes, when I start it again, the computer moniter shows nothing but a black screen and the computer sounds different when it starts normally. When this happens, I turn it off again hit the left side of the desktop and turn on again. Whenever I do this, the computer starts normally, and I go on the computer use.

    Yesterday morning, after a break of 2 days, acess my computer and it is random freezing thing once again. I force close down as one normally do, and the computer does not start and displays the same black screen and the same fan/air weird sound. I stopped him and I hit the side RIGHT this time, I think and when I turn on the computer, the usual blue HP screen appears with the establishment, boot, diagnostics and system recovery things. HOWEVER, after this screen, a black screen will appear with this weird blue symbol on the upper left corner, I have never seen this and it looks like a circle with a triangle and a Pentagon below and it remains essentially on this screen forever. When I try to hit the establishment, boot, diagnostics and the shortcuts to system recovery, on the lower left side of the screen, it says "Menu boot loading...". ' or whatever the shortcut of loading represents, but nothing ever happens. When I press the other keys, this tapping noise comes from the computer at each tap of the keyboard.

    I have no idea what to do, and at this point, my first priority is to save important files on the computer. Does anyone know what is the problem? I want her more than a problem of system rather than a virus problem because refusing the boot black screen thing lasts for years. My computer is 3-4 years. I enclose a sketch of what looks like the weird symbol.

    MY COMPUTER WORKS NOW!

    With the flash drive, I was able to access the BIOS, which before, I couldn't.

    Eventually my computer was in some strange sort of lockdown setting, I switched it back to activate and now its work! I remember save important things in the future. Thank you very much for your help!

  • M127FW MFP: Computer does not start after the installation of the MFP M127FW

    My computer does not start on my hard drive after installation of my new printer MFP M127FW unless I have first of all disconnect the USB cable between the printer and then turn on the computer.  My BIOS is set to boot from my drive hard, not from a USB key, so that makes installing the drivers M127FW MFP and software do on my computer?  I guess it has something to do with the Smart Install feature.

    Any help is greatly appreciated! :)

    My first suggestion is to do a system restore at this time point.

    second suggestion is to keep your external drive connected to the pc at all times.  only detach when necessary.   of course, it would be better to install a second hard drive in the computer instead.   in any case, keep your personal files out of the system disk is a wise thing to do.   You can also download and store files for free on the Microsoft Skydrive site.

    third suggestion is to keep your system set upward through executing a check disk and Defrag at least once a month.   Basically, you can open the Explorer and right-click on the drive letter.  then select Properties, and on the Tools tab, you will have the opportunity to run the disk check.  then reboot and do a Defrag.   where this disk check fails, then you will need to run it to the drive via a bootable cd prompt.

    Interestingly, I don't know if the bootable cd that you made you allows to run the disk check.

    so my suggestion is to do a series of tests using your cd bootable your computer works.  see if you can actually run a chkdsk/r at the moment with them.    If Yes, then if your constant worries are having bad sectors on the hard disk, chkdsk/r will identify and mark so windows will jump on them.    in any case, see if your boot at the moment media can run a check disk at all, and let me know.

    fifth proposal is to install "microsoft security essentials" like your anti virus program.  even if you have run ubantu, it is not likely to have been an infected copy.   anti - are most critical virus for windows and not not so much for ubantu or linux is because windows is a system of world class operations.    the people who make the virus deliberately their engineer for the windows operating system.   If, however, ubantu and linux have been just as popular as Windows, virus engineers would make infections for the o.s. too.     Although they no doubt, attacks are more frequent for the windows os.
