Hi Ndiddy88

Power on and off your computer three times

How do you do that?

Power on, when you see the Windows Logo - power off

Power on, it will then your computer will boot into the Advanced Recovery environment

Click Advanced Options

Click System Restore, see if you can go back to an earlier time.

If not, boot into the recovery environment again, then try performing a startup repair.

If that does not work, boot into the recovery environment, then click 'Go back to previous version of Windows'

If that does not work.

Hi Ndiddy88

TVALZ O.SYS is TOSHIBA ACPI-Based Value Added Logical and General Purpose Device Driver

Are you able to get into your PC or are you locked out by that BSOD?

If you are locked out, please try this:

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt . . . etc.

Please try each option one at a time, then see of Windows will boot . . .

Go to Troubleshoot - Advanced Option - Startup Repair

See if Windows startup can repair itself

Go to Troubleshoot - Advanced Option - System Restore

Check to see if you have a restore point you can go back to

If you do not have a Restore Point, go to Troubleshoot - Advanced Option - Startup Settings and click Restart

Upon restart, press 4 to enter Safe Mode

Once in Safe Mode, backup your data if you do not already have a backup

Open Device Manager and check to make sure all your Drivers are up to date

Reboot to see if Windows will start Normally

Answer 3

To know what exactly is causing the crashes, I need to analyze minidumps generated by crashes with WinDBG. WinDBG is the only tool which can do end to end complete analysis of ..dmp files generated by BSOD (Blue screen of death).

Go to C:\Windows\Minidump

Zip the contents of the folder corresponding to date and time of your crashes.

Upload the content to Onedrive or any other file sharing site for me to locate the problem

If you need help to generate Minidump - http://answers.microsoft.com/en-us/windows/wiki...

IF YOU ARE NOT ABLE TO GET INTO YOUR COMPUTER

Try to boot into safe mode

Power ON your computer and as Windows / manufacturer's Logo appears, Power OFF - Repeat 3 times

Now your computer will go into Advanced Recovery Environment

Advanced Options > Troubleshoot > Advanced Options > Startup Settings > Restart

Press 4 or F4 to enable Safe Mode (5 or F5 to enable Safe Mode with Networking)

Log in once Windows starts in safe mode

See whether you able to login. If yes, come out of this and start normally.
