The server could not bind to the transport \Device\NetBT_Tcpip_{457703E7-2849-40E4-A334-80F0DD6CF413} because another computer on the network has the same name.  The server could not start.

There is some conflict with some other computer in the same network. If you got any more BSODs in between, upload the dumps.

To know the computer name, preww Win + Pause/Break simultaneously, notice in "Computer name, Domain and workgroup settings: of the resulting window.

There is only one way to change the name, as far as I know; that is a clean install.

Uninstall the printers drivers; if you dont use that printer anymore.

Have you checked the names of the other computers in the network?
You upload the dumps, I will check them, for sure.

Apparently the situation is a bit better now, after making a few changes including the network driver update that I can check in the dumps.

Now, free up the startup.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus.
5. Apply > OK
6. Accept the restart.

Then try Memtest again. Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

Hope it will let you run this time. Observe it, let it run for 7 -8 passes, as koolkat77 suggested earlier. Is it showing errors, the red lines?

If yes, replace the RAM modules. If it passes clean, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.
