This problem can be chose if set in advanced settings of video: rendering mode or filter for DirectShow Video renderer to “Superior video processor” or “Enhanced Video Renderer (EVR).

In Media Player Classic, this option is View-Options-Playback-Output-Directshow Video-EVR.
In Bsplayer Pro, this option is Options-Preferences-Videos-Output video rendering mode-EVR (Enhanced Video Renderer).

Clear the check box in Control Panel->Folder Options->View->”Hide empty drives in the Computer folder”

If you try to erase the disc you receive the answer “The media is not rewritable” or “The disk is write protected”. Apparently was made by the label on the disk and the program define it as DVD-R.

To remove this label, go to Alcohol 120% and uncheck items in the Tools -> Options -> Emulation -> Ignore media type, in Daemon Tools select Hide CD-R Media.
After this re-erase these disks in Alcohol 120% or Daemon Tools.

Enable memory dump records

1) press the key combination Win + Pause
2) click Advanced system settings
3) go to the Advanced tab
4) press the button Settings in the Startup and Recovery
5) by default they will be saved in the folder %SystemRoot%\Minidump

Core dump analysis and identification of the driver that caused the error:

Option 1

1) download and install Debugging Tools for Windows.
2) download the batch file kdfe.cmd (Kernel Debugger Front End) with a script to facilitate analysis of the dump files created by Windows STOP errors (BSoD), original code taken on resource sysadmins.ru
3) extract the archive to any folder.
Note: If the Debugging Tools for Windows folder is not in the Program Files folder, the file kdfe.cmd should specify another path to the folder where you installed the Debugging Tools for Windows.
The path to the folder is set after the parameter set dbgpath=
4) open a command prompt and navigate to the folder you just extracted to kdfe.cmd
5) run the file by specifying the path to the file dump (in the example below, the file is called Mini1110307-01.dmp)
kdfe.cmd "%systemroot%\Minidump\Mini1110307-01.dmp"
6) wait for analysis. At the end you will see the driver, which served as the cause of the error.

Option 2

1) download BlueScreenView utility.
2) install BlueScreenView.
3) launch BlueScreenView.

Search dumps produced in %systemroot%\Minidump folder, you can also customize and own folder (Options-> Advanced).
To found a dump utility displays:
- In the top bar-file name, creation date, name of the stop error, the error code, settings, and driver, allegedly caused the problem (Caused By Driver).
- In the lower pane – (depending on the settings in Options panel–>Lower Pane Mode) all the drivers that are loaded at the time of the error, or only the drivers found on the stack. Among all drivers-the pink background are suspected to be causing the problem drivers. Also, the utility may display a blue screen, very similar to the one you are all so fond of.
Note: when defining a driver don’t need to rely only on filename column Caused by Driver. Should consider the drivers in the bottom pane (or only selected pink, if you have turned on all drivers), primarily focusing on non-system drivers.

Read the article by Brien M. Posey “Demystifying the Blue Screen of Death” on the site technet.microsoft.com. There you can search for explanations on the specific error.

Go To:Control Panel->Administrative tools->System Configuration->Boot tab->Advanced settings

5) clean cache folder C:\Windows\rescache
6) clear temporary folders (quarantine) your system protection (Norton, Kaspersky, Eset 32 and others), some worth to disable tracing.
7) download the Scanner by Steffen Gerlach to analyze the contents of hard drives. This program will help you to see which folder or file occupies much of your disk.

This sometimes occurs due to improper installation of the hidden partition System Reserved.
For example, if you have one hard drive, Windows 7 installation highlights the hidden partition System Reserved to protect bootable operating system files.
If during installation are two hard drives, Windows may incorrectly identify sometimes second hard drive and use it as a hidden partition System Reserved. Thus, he will not have a drive letter.

To add the drive letter follow these steps:

1) Disk Management snap-in: open the Start menu search box write diskmgmt.msc, and then press Enter
2) find your drive, it will not have a drive letter.
3) click on it and select Change drive letter and paths…
4) in the window that opens, click Add, select the desired drive letter and click OK.

If the disk does not appear in Windows Explorer, then restart your computer.

This problem may occur as a result of the root disk file or folder named “Autorun.inf”.
If you did not create its own protection against viruses using the autorun, then the file (folder) could create a program.
To correct this problem, do the following:

1) open Start-Control Panel-Folder options
2) click the View tab and select the “Hidden files and folders” to “Show hidden folders, files and drives”.
3) delete the file at the root of a drive or folder named “Autorun.inf”.
4) reboot the computer.
5) modify the disklabel (Win + R->label.exe->OK)
If you created the file “Autorun.inf” themselves, then simply add the following:
[autorun]
label=volume label
Instead the volume label you substitute the appropriate value.

In Windows 7 system uses a generic driver for SATA (internal device interface) and eSATA (interface external devices).
Therefore, regardless of which of them is connected hard drive system determines whether the device supports checkout function “On-The-Fly”.
If your system is using AHCI mode, then in the “Safely remove hardware and Eject Media” in your system tray will appear your hard drives. This is due to AHCI mode functionalities, namely feature swappable (HotPlug)–which is able to extract the hardware in a computer system during operation.
If you don’t use a mobile chassis (Mobile Rack) for internal hard drives and do not plan to retrieve them, you can disable their display in the “Safely remove hardware and Eject Media”.

Option 1. Install the native driver for my chipset to which connected hard drives. For example, for the Intel chipset driver for Intel®Rapid storage technology.

Option 2.Specify the system that the device must use the internal port. In Run (Win + R) or at the command prompt running as administrator enter the command:
reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\msahci\Controller(n)\Channel(N)" /f /v TreatAsInternalPort /t REG_DWORD /d 0x00000001
Where (n) is the number of the controller fo drive, (N) — the channel number. In most cases the default is 0 in both cases.

Repeat this step for each drive, replacing values on necessary. The number controller in most cases the default is 0 for each of your drives. Channel number you can look in Device Manager on the Details tab in the Properties of your hard drive. Channel values are numbers that begin with a digit 0.
For example, if you have 2 hard drives, you’ll enter the following commands:
reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\msahci\Controller0\Channel0" /f /v TreatAsInternalPort /t REG_DWORD /d 0x00000001
reg.exe add "HKLM\SYSTEM\CurrentControlSet\Services\msahci\Controller0\Channel1" /f /v TreatAsInternalPort /t REG_DWORD /d 0x00000001
Option 3. Use a third-party software.

1) download and install the program USB Safely Remove. This program will replace the built-in Windows function “Safely remove hardware and Eject Media” on own utility.
2) for the tray icon hiding when there are no connected device, enable the option “Hide icon when there are no devices to be stopped.” It is located on the settings tab of the “Look and Feel”.
