Hello Dr.Ahmed:

I looked for the specifications for the B5400 Lenovo® laptop, and based on them it seems that the graphics controller the laptop is using is: Intel® HD Graphics 4600, here is the link where you can confirm that: http://www.lenovo.com/shop/emea/content/pdf/Lenovo/bseries/en/B5400DSEN.pdf http://www.lenovo.com/shop/emea/content/pdf/Lenovo/bseries/en/B5400DSEN.pdfSo, please get in to device manager and try to un-installed the current graphics driver, right click on it and select un-install or delete, then please install the following driver manually, it is driver version 4463 the latest version available for Intel® HD Graphics 4600: Instructions to install the driver manually: http://www.intel.com/content/www/us/en/support/graphics-drivers/000005629.html http://www.intel.com/content/www/us/en/support/graphics-drivers/000005629.html Driver 4463: https://downloadcenter.intel.com/download/26079/Intel-Graphics-Driver-for-Windows-10-15-40-4th-Gen-?product=81496 https://downloadcenter.intel.com/download/26079/Intel-Graphics-Driver-for-Windows-10-15-40-4th-Gen-?product=81496 On the following link you will see a graphics driver from Lenovo's web site, you can also try this driver: http://support.lenovo.com/cr/en/products/laptops-and-netbooks/lenovo-b-series-laptops/lenovo-b5400-notebook/downloads/DS103421 http://support.lenovo.com/cr/en/products/laptops-and-netbooks/lenovo-b-series-laptops/lenovo-b5400-notebook/downloads/DS103421 Also, I found a site that shows a possible fix for this problem: http://www.troublefixers.org/laptops/fix-system-thread-exception-not-handled-in-windows-10/590/ http://www.troublefixers.org/laptops/fix-system-thread-exception-not-handled-in-windows-10/590/ NOTE: These links are being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there. If after trying those drivers the problem remains, then the best thing to do will be to get in contact with Lenovo directly to get further assistance, maybe a BIOS update is needed: Lenovo's phone number: 1-855-253-6686 Lenovo's support web site: http://support.lenovo.com/ http://support.lenovo.com/ http://www.justanswer.com/sip/lenovo?r=ppc|ga|1|General%20-%20Rest%20of%20World|Lenovo&JPKW=lenovo%20technical%20support&JPDC=S&JPST=&JPAD=76040132283&JPMT=p&JPNW=g&JPAF=txt&JPCD=20120207&JPRC=1&JPOP=Darren_Andrew9sec_Trans&mkwid=sEPOiwM6O_dc&pcrid=76040132283&pkw=lenovo%20technical%20support&pmt=p&plc=&gclid=Cj0KEQjw0MW9BRDxtYTn2_S699MBEiQAw33y40N... http://www.justanswer.com/sip/lenovo?r=ppc|ga|1|General%20-%20Rest%20of%20World|Lenovo&JPKW=lenovo%20technical%20support&JPDC=S&JPST=&JPAD=76040132283&JPMT=p&JPNW=g&JPAF=txt&JPCD=20120207&JPRC=1&JPOP=Darren_Andrew9sec_Trans&mkwid=sEPOiwM6O_dc&pcrid=76040132283&pkw=lenovo%20technical%20support&pmt=p&plc=&gclid=Cj0KEQjw0MW9BRDxtYTn2_S699MBEiQAw33y40N...
