  A1. Wise move IMHO. The computer seems "snappier" now?

  A2. I can't imagine that another owner of a Dimension 8400 (or 4800?) has not encountered this problem before.

  A4. Welcome & thank you for your comments.

  In fact, there is something else you may need to do: it turns out that KB2607712 is replaced by the KB2616676 in Vista & Win7; Windows XP needs to have both installed [despite the mention you referred in your post on September 14, above] !!!

  => So if Update for Windows XP (KB2607712) is NOT listed in Add/Remove Programs, you will need to manually download/install a revised version [long story, involved - you don't want to know]:

  ~~~~~~~~~~~~~~~
  ACTIONS:

  1. open Internet Explorer to http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=27244 & click on the button CONTINUE.

  2. after VALIDATION, download the installer for KB2607712 & save it to your desktop - NOT run again!

  3. close all open applications (that is, anything with an icon on the taskbar).

  4. double-click on the file that you saved in #2 above to install the update. Follow all the instructions (reboot required).

  5. check that the Update for Windows XP (KB2607712) is now listed in Add/Remove programs.

• Windows Vista does not start. The BIOS loads then black screen with blinking cursor.

  So my friend told me that his PC was not working. When you press the power button on the pc, the screen of the Dell BIOS load but instead of starting then Vista it shows just a black screen with a blinking cursor. Still, the BIOS detects the hard drive and has the ability to boot from it, but it just that again. I tried the recovery disk windows, and when you click on the "Repair" option when it loaded usually shows a list of the operating systems installed and their hard drives. There is no listed on the Vista recovery cd. Manually, you can browse and find the partition from the OS than its sequel, and clearly see the windows directories. It all simply not start, nor let the recovery disk to fix it because the operating system is not detected. I plugged the hard drive on my pc with the same results. Then I started my Win 7 and Explorer, disks and partitions are once again still visible with the appropriate directories. Windows says the drive is working properly and has no file system errors. When viewing in the hardware Manager, he says it's healthy (primary, active partition). My hard drive working correctly says healthy (boot, pagefile, primary partition). Why used it boot and why the recovery disk not recognize the operating system and how can I fix it or do I need to format and reinstall vista?

  2. what type of installation you have done, it's a custom Setup or an upgrade.

• Windows starts, but does not charge not (black screen with cursor)

  [Sorry for the long post, but I feel the need to explain my situation]

  I have the following problem:

  I turn on my PC, and Windows shows it is normal loading screen, then it goes in a completely black screen, with just the mouse in the middle. By the size of the cursor, I can say that it is in a low resolution, probably 800 x 600 (compared to my usual 1920 x 1080). I am able to movements of the mouse, but with no particular purpose without something to click on. No other keyboard input seems to work, except for press SHIFT 5 times, which shows the keys dialog box to self-retaining (with just 'yes' or 'No' options, no other connection); and Windows key + U, which shows the ease of access Center. CTR + Alt + Del does NOT work.

  So far, that's what I tried (in chronological order):

  1. Start in Safe Mode, Safe Mode with network, safe mode with command prompt Mode, start low resolution video, last known good configuration: all give the same result as to start normally.
  2. Repair of your computer:
     1. Startup Repair: find the registry errors (I realized and fixed this more later on)
     2. System Restore: did not find any previous restore points (I know with certainty that there is, I took the habit of making regular restore points).
     3. Windows memory diagnostic: not found error.
     4. Command prompt:
        1. Ran the command chkdsk /f r, has no error report.
        2. Ran sfc/scannow: I don't remember the exact report, but he asked to restart the computer to complete the repair of the problems. I rebooted and ran the new order for the same result.
        3. Forced the scan with: sfc/scannow damaged = c: \ /offwindir = c:\windows, concluded and repair errors, not always not load windows.
  3. Ran Dell Diagnostics start, found no errors.
  4. Startup Repair ran found once again the registry errors. I found the solution to this in a forum for Microsoft Help ( answers.microsoft.com/.../f77d5355-b8be-41d6-af24-cae994e1768f ) and fixed the problem. I rebooted, but the problem persists.
  5. Startup Repair does not detect now no error. I tried restoring the system again, we find 2 restore points dated AFTER the beginning of my problem. I decided to restore it in any case, but none of them worked.
  6. I ran Windows Defender in offline mode:
     1. Quick scan: and found 2 threats and remove.
     2. Full system scan: found 4 more threats, removed 2 of them, the other two could not be removed because they were in an ISO file.
  7. I've tried steps 1, 2 and 3 with no luck.

  With every step, I am aware that I am closer to having to reinstall Windows, then I decided to see if I could still access my HD to save my personal files. I did a live Linux CD (with Ubuntu), but I have a problem of mounting the readers, because they are in a RAID0 configuration. "sudo dmraid s" gives the following error: "ERROR: Sie: number of devices in RAID wrong value"isw_dbdffjficc_ARRAY0"[1/2] on/dev/sdb.

  Important details:

  I changed my graphics about 4 months ago (a 750ti of Nvidia GTX for an ATI Radeon HD 6450), and told me that I can run short with the power supply. The new card requires a minimum of 450W, and I think that my diet is 460W. This may or may not have something to do with this question, I have no idea.

  My 2 hard drives of 500 GB RAID0 configuration has brought me a lot of problems of the day 1. One of the HARD drive would be randomly (I am able to hear a clicking sound different when this happens) failure and the computer would break. At the start, he would ask a boot device. The Dell boot utility would then recognize only 1 readers, but would end without errors. After a reboot or two, everything would be fine and would be boot windows normally (apart from the usual error recovery screen) with no sign of corrupted data or anything. As I said, it happened are the arrival of my PC, but restarting a couple of times still attached. From now on, the two HD seems to work very well, the Dell utility recognizes two of them and found no errors in one of them, and I can access any directory from the command prompt.

  Is there anything else I should try before reinstalling Windows?

  Before the installation, I really wish I could recover my files (I have important documents of the College), is it possible to do this?

  Sorry again for the very long post (and for any errors of language, English is not my native language) and thanks in advance.

  Since you have not yet had your data readers. I recommend a Windows installation without formatting the drive... I don't like this solution, but at this point, you have probably tried everything.

  Use a reinstallation of Windows 7 installation DVD, make sure that you select...

  Select custom: Install Windows only (Advanced)

  

  If you do not select one of the route options and everything simply highlight the largest partition and click Next:

  

  Windows will dump all the old Setup files into the Windows.old folder

  

• U2515H, black screen with error during startup until the Windows login screen

  It is a half frustrating work situation.

  Was doing this:

  display port HDMI card--> cable HDMI - HDMI--> HDMI U2515H port

  This configuration has worked in Windows 7, with a 2560 x 1440 resolution reached.

  However, when you perform a reboot of the machine, the screen went black and impossible to display the BIOS POST screen (these text showing the amount of RAM you have, what are the HD detected, etc.). In addition, there was an error message on screen, saying:

  "The current moment of entry is not supported by the display. Please change your timing of entry to 2560 x 1440, 60 Hz or any other listed monitor calendar according to the characteristics of the monitor"

  The message error and white screen persists until Windows loaded to the login screen. This means that I can't see even the Windows logo, or the safe mode selection screen if I press F8.

  It's so no way for me to go into the BIOS to change any parameter, or do a boot was secure.

  Tried to use a DVI-HDMI converter and also a DVI-HDMI cable to make use of the DVI port of my video card. Still the same error as above. Worse still, this implementation does not work in Windows 7, gives me a white screen.

  I'm sure the DVI port on my video card works, cos it can work with my old Samsung monitor. Inspired by the present, the steps to be followed to the letter, may force the U2515H to show the BIOS screen:

  1. stop down and power down the computer.

  2 port DVI video card-->--> old Samsung monitor DVI port DVI - DVI cable

  3. turn on your computer. The screen of the MESSAGE on the Samsung monitor.

  4. go into the BIOS by pressing del screen

  5 disconnect the cable DVI - DVI video card DVI port.

  6 port card video--> cable DVI DVI - HDMI--> HDMI U2515H port

  The thing is, if I have to keep the old monitor, why bother to buy the new U2515H from Dell?

  So, how can I get the U2515H to accept the signal from my video card during the POST screen and the start-up phase, without going through the tedious steps each time? Thanks in advance!

  Material:

  motherboard: Asus P5K - E Wifi (latest version of the BIOS)

  video card: Galaxy 8800GT (DVI, HDMI)

  It seems that your motherboard ASUS has a slot PCIe x 16 blue. If one of the beaches mid PCIe x 16 graphics cards will suffice. Go here. I have this sort by Nvidia PCIe x 16 2.0 video cards, low to high price. You look for one with DP or CDM. Or simply go to a local store and search the PCIe x 16 video cards with DP or CDM.

• Disc Read Error black screen with the mouse cursor

  Hello world.

  I'll apologize in advance if this was picked up elsewhere, however, I've been unsuccessful with validated solutions, I found.

  I am trying to reinstall windows 7 on my laptop. I used to have win8 but got fed up with the thing of 100% of the disk. I reformatted my drive and installed win7. Everything was ok for a few days, and then he started getting lag. I decided to do a chkdsk (c:/f/r/x). He asked for a reboot in order to complete the process. After the reboot, chkdsk found a couple of bad sectors (I don't remember what files should be moved) and restarted again. This has happened 3 times in total.

  The last restart led me to the «a read disk error occurred press Ctrl + Alt + Delete to restart» It comes as I can get without the disc...

  Then I tried an official win7 installation disc which gets a little further. After lingering on the 'Starting Windows' screen for a few minutes, the screen turns black with only the white slider.

  I changed my BIOS settings also so:

  * SysInfo *.

  -No change

  * Advanced *.

  -CPU - disabled power saving mode

  -EDB (Execute Disable Bit) - active

  People with disabilities - Mode BIOS fast-

  -AHCI Mode Control - Manual

  -Set the AHCI mode - people with disabilities

  -USB S3 Wake-Up - disabled

  * Security *.

  -No change

  * Start *.

  -Boot Device Priority

  1 SATA CD (DVD player)

  2 SATA HARD DRIVE

  -Touch Mouse Pad - people with disabilities

  -Secure Boot - people with disabilities

  -Selection of the Mode of OS - OS CSM

  -Internal LAN - enabled

  -PXE OPROM - disabled

  [Please note that I used setting 'UEFI and CSM the OS' aswell in the Mode of the OS but kept a CSM OS as long as there is no point using both with win7]

  I have used most of the F8 options and get the w/cursor black screen.

  Start in safe mode always seems to stall on "... \drivers\disk.sys" what "loading Windows Files". After 5-10 minutes on this, it would eventually return to the screen Black w/cursor...

  Jacky help would be really appreciated, soon.

  There is no point in trying to reinstall Windows. If your drive is faulty, then a new installation will not fix it. To get a reliable report on the status, you must download and run the web page of the Disk Manager Diagnostics tool.

  Hi Tom,

   
  Thanks for posting your query in Microsoft Community.
   
  According to the description of the problem, I understand that your computer has become suddenly black and now in any start-up situation with the blue screen repair option, correct me if I'm wrong.
   
  Blue screen (sometimes referred to as errors or errors of STOP code black screen) errors occur if a serious problem, windows to shut down or restart unexpectedly. You might see a message that says: "Windows was arrested to avoid damaging your computer."
   
  To better understand this issue, I would like to know the following information:
   
  1. What is the brand and model of the computer?
  2 did you receive an error message before the computer went black?
  3. did you of recent changes to the computer before this problem?
  4. are you not able to start on the screen?
  5. When you say "I tried to put the windows disk 8 in which he refused to take", is the DVD drive on the computer that works well or not the same bed on another computer in Windows 8 support?
  
  When you say "on the repair options, I try to restore my PC but it requires a password for my account profile computers that I have disabled months ago" I suggest you try the enter without specifying a password and check if it allows to connect to the user profile that you have disabled the password long ago.
   
  If you are not able to connect with the system restore without entering the password, and since you're telling the DVD of Windows 8 refuse to take, I suggest you to create recovery USB Windows 8 media and then try to repair the computer.

  (c) restarts the computer, when you see the logo of the manufacturer, continue to press the Boot option menu key to enter the boot menu and change the option to boot in DVD ROM.
  (d) once you start your computer by using Windows 8 DVD or system repair disc, a black screen is displayed with the gray text "press any key to boot from CD or DVD". Press a button on any.
  (e) select the exact time and the type of keyboard.
  (f) click on repair your computer in the lower left corner
  (g) click on troubleshooting, advanced option and then click on auto repair.

• MacBook (2010) starts with black screen with flashing Apple logo

  I recently got ahold of a Macbook Pro 2010 running very slow so I did a reinstall of the operating system (which was a living nightmare, Macintosh is not as easy to manage as it was at the time of PowerPC) once I got to the top and running, I decided to upgrade to the latest version of El Capitan (an update (not an upgrade I already had a version out there) once I rebooted and let the computer do its thing he began to start up normally, but after finishing the progress bar, he went to a black screen (with the screen still on) that flashed the boot from time to time Apple logo. I forced shut down the computer and start in safe mode with success (that's how I'm typing this post now).

  Thanks in advance.

  When you reinstalled, did you remove any third-party system before reinstalling.

  A Mac that runs in Mode without failure, but are generally not normally indicates some incompatible system changes.

  Software common problems are things that are intended to clean, protect, optimize, accelerate, or otherwise maintain your Mac.
