Toshiba Satellite L755-s5306 Blue Screen of Death BSOD

Toshiba Satellite L755-S5306 Blue Screen of Death BSOD

If you are having “The Blue Screen Of Death” (BSOD) with a Toshiba Satellite L755-S5306 you are not alone. Please leave a comment in hopes enough of us can find each other and come up with a more permanent solution than the work around I present here. As of the day this was posted there was nothing index into Google or Toshiba’s forums regarding a Toshiba Satellite L755-S5306 having a BSOD problem.

Unfortunately I don't have an answer or solution so much as a troubleshooting alternative and that is to install Ubuntu 11+. I would rather use windows7 but the fact that Ubuntu runs without crashes indicates that my problem is a Windows 7 software issue. Windows7 is conflicting with either the hardware within my computer or some pre-installed factory software.

This laptop is new (it has only been out of the box for 3 months), has an i3 processor, 4GB of RAM and is still under warranty; until Sept. 10, 2012. I have yet to contact Toshiba but will. Within the last month (Feb. 2012) I started to get multiple BSODs out of no where. These were the following error messages:

1. KMODE_EXCEPTION_NOT_HANDLED
Caused By Driver : luafv.sys

2. KMODE_EXCEPTION_NOT_HANDLED
Caused By Driver : Ntfs.sys

3. SYSTEM_SERVICE_EXCEPTION
Caused By Driver : ntoskrnl.exe

4. PAGE_FAULT_IN_NONPAGED_AREA
Caused By Driver : ntoskrnl.exe

5. KMODE_EXCEPTION_NOT_HANDLED
Caused By Driver : partmgr.sys

I have done all of the following hoping to solve this issue with no luck:

1. Re-formated computer with factory shipped disk. Five Minutes after I did this I got the BSOD. That definitely eliminated the idea that it was something I had installed or that it was a windows update conflict.

2. Got all window updates. That didn’t help.

3. Checked all drivers manually one by one through the device manager for updates; according to the Device Manager there was no updates.  
*However, this is the only area of hope that I have. I downloaded the program Drive Max and it list several drivers as outdated. I can only download two a day and install them. After I have them all installed I will report back as to whether or not I have a BSOD.

4. Updated BIOS. Toshiba did have a BIOS update available but it didn’t work.

5. Ran window's memory diagnostic tool. It reported  no errors.

6. Check Disk with no errors

After all those failed attempts I took to the Internet. That is when I ran across a post online where a person stated they had the same problem with a similar Toshiba laptop and switched to Ubuntu. After doing so they had no problems. I did the same and agree I have no BSOD or other issues after one week. So I hope this helps for now. If anyone finds a windows based solution please leave a comment.

Access External USB Hard Drive via Virtualbox W/ Linux Host

How to access an external USB hard drive via Virtualbox with Linux Mint 8 or higher as Host.


For starters I have seen a lot of work arounds with this problem so the solution I am presenting here is only one of many. I am presenting this solution because it makes the guest OS recognize the external drive as if it were plugged into it directly; like it was the host.


Step One

If you have not already done so download and install VirtualBox.


Step Two

If you have not already done so download and install VirtualBox's Extension Pack. Once that is accomplished reboot your host OS.


Step Three

Install guest OS within VirtualBox (in my case XP).


Step Four

After installing guest OS boot it and install Guest Additions in guest OS. After that reboot guest.


Step Five

Connect external USB hard drive to computer.


Step Six

Shutdown guest OS and go to VirtualBox's main menu. Select Guest OS and then select settings. When the settings window opens select USB in the left hand menu.


Step Seven

Make sure the two options below the USB subheading are enabled. Next on the right hand side of the settings window click on the icon of the USB with a green addition sign over imposed. After clicking this your external USB hard drive should be an option to select; click it. However, if it is not an option at this point and it is correctly connected to your computer you need to reboot your host OS and start at step five again and proceed.


Step Eight

After successful completion of Step Seven open your Linux menu and select “Users and Groups”. Then unlock your users. Select your user name and then select “Properties”. When the new window opens select “User Privileges”. Scroll down to “Use VirtualBox” and make sure that it is enabled.


Step Nine

Finally, go back to “users settings” main window. Select “manage groups”. Scroll down to “Vboxusers” and select. When the new window opens select your user name and close.


That's it your done. When you boot into your guest OS it will automatically grab your USB drive.
