BSOD working with 3dsmax, UDK and Unity3D opened.

The latest crash was corrupted and unreadable. Probably related to your SSD incompatibility I warned about...

Ok, I take it off.
Have you got a great software in mind to duplicate a hd ?

SSD - Install and Transfer the Operating System may help. You would do it from the SSD to the HDD, instead, though.

Ok, no more crash since I pulled off the SSD. But a new one here, like the first, with UDK and 3dsmax running.

Related to your graphics card. A few things to do:

1. Make sure Catalyst Control Center is not overclocking the card without your knowledge.
   
   
2. Try older drivers. Check each driver in the set from 11.9 - 12.3.
   1. Download the drivers you want for your display card(s)
   2. Click Start Menu
   3. Click Control Panel
   4. Click Uninstall a program
   5. For AMD:
      • Uninstall AMD Catalyst Install Manager if it is listed (this should remove all AMD graphics software and drivers)
      • If AMD Catalyst Install Manager is not listed, use the following method to uninstall the graphics drivers (this applies to onboard graphics, as well):
        1. Click Start Menu
        2. Right Click My Computer/Computer
        3. Click Manage
        4. Click Device Manager from the list on the left
        5. Expand Display adapters
        6. Do the following for each adapter (in case you have multiple display cards)
           
           • Right click the adapter
           • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
           • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
           
           
           Alternatively:
           
           1. Login as an adminstrative user
           2. Click Start Menu
           3. Click Control Panel
           4. Click Hardware and Sound
           5. Click Device Manager (the last link under Devices and Printers)
           6. Expand Display adapters
           7. Do the following for each adapter (in case you have multiple display cards)
              
              • Right click the adapter
              • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
              • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
      • Restart your computer after uninstalling drivers for all display cards
      • Install the driver you selected for the display cards once Windows starts
   
   
   
   
3. Install the drivers without the Catalyst software:
   • You should already have the installer downloaded and installed the drivers/Catalyst software, so your drivers probably exist in C:\AMD\Support\xx-x_vista_win7_64_dd_ccc where the x's replace your version number of the driver software.
     
   • Uninstall all AMD software related to your graphics card by uninstalling AMD Catalyst Install Manager in Start Menu -> Control Panel -> Uninstall a program
     
   • Restart your computer.
     
   • Re-install your drivers from the C:\AMD\Support\xx-x_vista_win7_64_dd_ccc folder using a similar method to that in OPTION TWO of Drivers - Install Vista Drivers on Windows 7

For each of the above steps, test by doing your normal routine for a while and do the tasks that normally cause crashes. Test for twice as long as it typically takes to get a crash (on average).

Am on it, thx.
