Computer does not restart after the removal of volatile environment HKEY?

Summary: I was trying to remove a cluttered game persistent of my programs list title

so I'm in regedit (register edit) and tried to find (failure) and in the process, I deleted some other persistent games already removed under the registry 'Uninstall', but then I made clownish error after pressing a different register list of folders and what is called 'Unstable' deleted under current HKEY/user and then I could not access the Add/Remove programs of control panel list (he doesn't respond to my clicks) , and when I restarted the PC,.

I forgot to enter the normal restart and was still stuck at the start-up screen, also the Login usual words of greeting don't pop up, and only a few mojibake flashed on the screen for one second before letting me eternally stuck at the loading screen, so I guess that the deleted file was something important.  In addition, I can still acess the BIOS Setup Utility.I have the tool, make a HARD drive Diagnostic test but its takes time.

Then... help please? : o

I'm typing this on a spare, slower computer Win7 btw

I didn't have a State previously saved for the restoration of the system, so it couldn't be used, other options?

Things are getting more and more difficult...

You can restore your registry files manually to a previous point through the steps described below. The process is complex and requires some careful typing. Ask a computer-savvy friend to help you if you lack experience in this field. You may reset your password to an earlier value.
1. keep tapping F8 during the first phase of startup.
2. select Repair from the menu.
3 log in as administrator if you are prompted.
4. Select repair when prompted.
5. Select the command line in the menu.
6. identify the correct drive letter for your Windows installation. It could be one drive other than c, but it will not X:. You do this by typing commands
DIR C:\Win*
Dir D:\Win*
dir E:\Win*
until you find the Windows folder.
I'll call this "Q:" drive
7 type these commands:
CD /d Q:\windows\System32\config
xcopy *. * Q:\MyRegBack\
CD RegBack
dir
8. review the dates of the software, system, and SAM files. The files created before or after that is your problem?
9. If they were made before the problem appeared, you can then type these commands:
copy software / y...
/y copy system...
/y copy Sam...
(the two points are part of each order)
10. restart normally. If things don't work then you can go back by copying files from the original register of Q:\MyRegBack to Q:\Windows\System32\config.

  • 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.

  • 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!

  • Problem: My computer hangs and does not restart after the installation of MS Update KB2479628.

    Tuesday February 11 I turned my hp Compaq nx7300 off I saw that she was installing updates I thought that nothing of what I had set to automatic updates. On Wedndesday that I have tried to re - turn on my laptop it installed updates. I got a black screen with white writing. The laptop then ran restoration of boot, but he was not able to repair itself and turns off. I tried to turn it back on a few times that I was in total disbelief that a MS Update would do this to my computer, it still does not.

    I tried to start the computer in safe mode, but it does not work.

    I tried to do a system restore but evertime I tried it there was an error, I tried all eight restore points but all back "an unspecified error occurred during system 0x800700b7 restore.

    "In restoration of start I clicked on ' view diagnostic and repair details" it said all tests have been performed with success, but at the bottom it says ' root cause found - boot critical file D:\Windows\system32\ntkrnlpa.exe is corrupt.

    I had to reinstall windows 7 pro three times so far and have now developed to the point that it is KB2479628 update of MS that is causing the problem. I the have not installed this time and have had updates to the manual

    What can I do about this problem, I spent at least 20 hours on this problem now, and looking for the many other forum of people seem to have similar problems. I'm worried that KB2479628 will settle by accident when I want to install some other updates?
