can't startup computer

[tomatoes210]

I was replacing the internal fan of my hp dv5220us laptop today. Afterwards, it won't startup. I did not have any problems with replacing the fan. But I think I may have done some harm during the process of taking my laptop apart. After I put my laptop back together, there would be nothing showing on the screen when I turn it on. I would hear the usual computer sounds as when there are no problems and see the usual lights light up at the beginning as well as hear the fan. The light for the wireless connection usually lights up about a minute after I turn on the laptop but it did not light up after I waited. Usually i need to hold down the power button a few seconds before it turns off but it did immediately when i pressed the power button. During the fan replacing process, I took out the screen, battery, hard drive, keyboard, ram chips and just about everything.
Supposing I didn't short circuit my laptop, what other possible problems could there be?

Technology talk show host Leo Laporte said that notebooks are very difficult to reassemble correctly & that the times he tried it even with good directions he wasnt able to get back together correctly. Once I tried to open up a friends HP DV6748 for a similar reason (ie, to acess the CPU fan), I sensed (after removing the screws) that I would never get it back together right.

Leo would probably advise that you check the ribbon flex cable between the LCD & the MB. An issue that occurs during dismantling is to inadvertently break a wire in the cable and/or in one of its connectors. I would concentrate on disassembling the top (ie, LCD portion) & see if it is possible to manually flex/manipulate this ribbon cable while the machine is running. A computer shop should be able to order a new cable for you.

OP here.

I took it apart again and this time got the screen to display. I am pretty sure all the connections and screws are properly placed. However when I start the computer, i get this screen that begins with "we apologize for the inconvenience..." and it has a paragraph saying something about a possible different hardware.

It gives the following 5 options:
safe mode
safe mode w/ networking
safe mode w/ command prompt
lost known good configuration
start windows normally

then a timer on the bottom.

It doesn't matter what i choose, it goes to the microsoft windows xp loading screen and then a blue screen flashes for a second before it returns to the screen above with the 5 options. I do have the option to enter setup though.

Does anyone know what may be the problem or what steps I should take to figure out the problem?

 

[tomatoes210]

In its entirety, this is what the screen says:

"We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this.

If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and folders, choose Last Known Good Configuration to revert to the most recent settings that worked.

If a previous startup attempt was interrupted due to a power failure or because the Power or Reset button was pressed, or if you aren't sure what caused the problem, choose Start Windows
Normally.

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Last Known Good Configuration (your most recent settings that worked) Start Windows Normally

Use the up and down arrow keys to move the highlight to your choice.

Seconds until Windows starts: 30"

OP here.

I was wrong above about choosing safe mode. Actually, after choosing safe mode, many lines get displayed with
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS\system32\Drivers\....sys

where the ... is different each time.
Afterwards it goes back to the screen with the 5 options.

Sounds like a driver or a critical Windows file got corrupted the first failed boot. Can you do a repair install?

 

[C1]

It shouldnt have happened, but it sounds like a system file on the HDD got damaged. Ordinarily the fix would be to just do an OS repair & you would be good in 20min or less. If you only have HP's utilities, then probably all you can do is restore to factory (not sure what HP has provided beyond this with your model).

Someone on this forum will come to help you. First though, verify that the boot loader is correct. If not, there are freeware utilities such as NTFS DOS which can be downloaded to view & write fix HDD files (like NT Loader).

OP here.

Considering that my internal hard drive is newer than my laptop and that it is one of the first and easiest pieces to remove, it seems weird if that is what is malfunctioning. I placed my CD which I used to install windows(not HP's utilities) in and booted from the CD but it could not detect my internal hard drive. But it could detect the partitions on my external hard drive. I tried installing windows on a partition in my external harddrive(which is an internal desktop hard drive) but then after restarting, i could not continue with the installation process.
Is it likely that another component inside the laptop is malfunctioning such as the adapter that the internal hd is attached to? It seems to recognize I am running windows but could it be something else that is causing it to not fully load?

Boot into the BIOS and see what is available there for HDD recognition and settings. It is possible some setting related to the HDD simply got changed. If the HDD cannot be seen in the BIOS then take out the HDD & carefully reinsert it making sure that good connection is being made. If you see a setting in the BIOS related to AHCI you might want to try it in IDE instead (or vice versa). In any event you will need to detect the internal HDD. You may have to use the external enclosure to test the internal HDD (ie, that it operates & can be see by the OS booted from CD; also you will have at that time opportunity to install the HDD from the external enclosure into the notebook to see if that one can be recognized).

Go to its operating system part that is highly responsible for controlling hardware and coordinating it as well. Such types of problems are basically related to operating system. Thanks for sharing.

I am not detecting my hard drive under system configurations>boot options. It seems my bios is missing some features. It only has Main,Security,System Configuration,Diagnostics, and Exit.

Sounds like your not in the BIOS but instead in the notebooks boot selection utility screen. When attempting to boot, look around carefully (usually along the lower left edge of the screen) for the key that should be pressed to enter the BIOS. The message will only display (very small print) for a couple seconds each time. Usually its one of the following keys: DEL, F1, F2, F10 or F12.

Try restarting the computer while holding down F10.

There are two choices at the bottom of the screen for like one second before it boots. One is to choose the boot order. The other is to enter bios which is f10. I did enter bios(the blue screen) but could not find anything about "HDD recognition and settings" and the only other place that I thought the HDD should show up is the choices of boot options. I think this is where it displays all possible places to boot that it detects and it is not actually the place for switching the order of ALL POSSIBLE boot options.
Thanks for replying.

If you have taken the laptop all apart there is a chance you may have done something to the Bios. It could be trying to boot a USB adapter or drive. Try to change the boot options from 1-CD and 2-HDD.
once this is done and it still does not boot then put the boot cd (if you have one) and do as one previous says to repair the OS system.
There is other steps but this would be the first before you try and do a recovery or a boot.ini replacement.
Good luck!

What exactly could I have accidentally done to the bios? I know everything is in the proper place but I may have damaged something in the process. I tried the HDD boot option but it just comes up with the screen with the 5 choices as I noted above. I put the boot cd in but it does not detect a hard drive.

First, I don't think there's anything wrong with the BIOS or HDD. You're getting WINDOWS boot errors which means it's spotting the hard drive, trying to boot then hitting a corrupt file. At a guess, the file got corrupted during the improper shutdown after you powered on the first time you rebuilt.

As to why the boot CD ain't finding your drive... do you have access to any other bootable CDs (e.g. a Linux liveCD such as knoppix) with some diagnostic tools on. They might be able to read and allow you to backup any important documents.

A possibility is AHCI mode is enabled. Older OSes (XP and before, not sure about Vista) needed drivers to access hard drives in that mode which caused issues with installs as the install CD didn't have those drivers in place. I can't tell you of the top of my head where in the BIOS that is (but I'll hazard a guess at System Configuration)

Hope this helps a bit,
Michael

Whats the error code that comes up when the computer crashes on startup? Should look something like 0x0000007B (0xffffffff 0xffffffff 0xffffffff 0xffffffff). This code can be invaluable to diagnosing the problem.

If the screen goes by too fast to read, there is a way to stop it. Keep hitting f8 on statup and it should bring up a boot options screen. You'll see the safe mode options at the top, followed by a list of other options. Look for one that says "disable automatic restart on system failure" (or something like that) select that option. Now the BSOD show stay on the screen and give you a chance to copy down the error code.

Post the error code here; or google it to find out more about what could be causing the system crash. Its not always very specific but it can help narrow things down.

Also, not to be a dick, but if you don't even know what the boot menu looks like on windows, you probably shouldn't be taking apart the laptop.

A problem has been detected and windows has been shut down to prevent damage to your computer.

If this is your first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Technical information:
*** STOP: 0x0000007B(0xBA4D3524, 0xC0000034, 0x00000000, 0x00000000)



I got the same blue screen as shown here: http://oxle.com/uploaded/18/5/error_vmware_stop.png.

Here is the linkie to the Microsoft Support page for your STOP error. I've had a quick look through, but I'm now late for work so I'll try to help later...

 

[Devilpapaya]

0x0000007B INACCESSIBLE_BOOT_DEVICE: this is generally caused by either a physically damaged or corrupt HDD.

My first suggestion would be to pull the harddrive and attach it to another computer and run "chkdsk <drive letter>: /r (or /b on vista/7)" from command prompt. This is windows scan utility that tries to recover corrupt and unreadable data from the harddisk. Its (by far) not the best tool around but its also the easiest/quickest to use.

You can also run the scan if you boot from a windows recovery/install disk, if you have one.

Blue screen of death with boot loop:

STOP 0x0000007B (0xBA4D3524, 0xC0000034, 0x00000000, 0x00000000)

For the record I tried the following without success on Windows XP Home OEM SP3:

Recovery console fixmbr
Recovery console fixboot
W98 FDISK /mbr
Remove disk, attach to another PC via USB disk caddy, then run CHKDSK /f (more precisely right click on partition -> tools -> error check)
Copy partition off drive, erase all partitions, create new partition, check disk works with DOS, erase it, copy failing partition back to drive (no luck)

I think this is a driver problem inside the partition. Mine was FAT32. But apparently

"The '0x0000007B' part refers to an inaccessible boot device
(e.g. the harddrive), and the "0xC0000034" part refers to
a device driver missing from the system...."

In my case I suspect it may have been a SATA disk driver, possibly associated with NTFS partitions (hence not there for FAT32). I was not able to find such a driver for the Samsung HM120JI disk. This laptop (Acer 5673WLMi) had no BIOS option to run the disk in IDE mode. Perhaps the driver could have been loaded via the recovery console dialog "Press F6 to install 3rd party SCSI or RAID driver." I don't know.

I had to do a clean install of windows to a new partition. Since the Acer had lost its recovery partition I had to find a windows XP home SP3 OEM disk in order to re-use the 25 character CoA code on the back of the laptop. The old partition could only be used for data access. Sad mess.

Are you positive that the hard drive is connected properly? It's possible that it's a loose SATA connector.

If it is, get to a command prompt (should be an option somewhere in the windows CD...it's been a while so I can't give specific instructions), and then run chkdsk C: /R. It will take a while, but it will fix any errors it finds and mark any bad sectors so that nothing can be written to them and cause future errors.
