Windows 10: Left shift not working when using CTRL SHIFT ESC for opening task manager

So I got a new keyboard, and although the left shift key functions normally, when it comes to the short-cut of opening up the task manager, via CTRL SHIFT ESC. When I try using the right shift key, it works. When I use my laptop's keyboard, both shift keys work. Is there any reason why this would be happening? Is there a way to diagnosis this problem?


Note: I am using the Dell XPS 9550, with Windows 10 build 18363

Keyboard Issues, LEFT SHIFT + LEFT CTRL + L/R ARROW doesn't work on travelmate P645-S windows10

Recently i am facing issues with my laptop. Key combinations doesn't work especially with SHIFT.

List of combinations (Not working) :

LEFT SHIFT + LEFT CTRL + LEFT ARROW

LEFT SHIFT + LEFT CTRL + RIGHT ARROW

LEFT SHIFT + LEFT CTRL + UP ARROW

LEFT SHIFT + LEFT CTRL + DOWN ARROW

RIGHT SHIFT + RIGHT CTRL + RIGHT ARROW

List of combinations (Working) :

RIGHT SHIFT + RIGHT CTRL + RIGHT ARROW

CTRL + C, CTRL + V, CTRL + X

Other than above 'working' combinations no other combination works with CTRL and SHIFT

Please let me know why this issue is occurring!

Is this a hardware issue/ software issue?

i have updated keyboard drivers, also uninstalled and restarted laptop & let drivers install automatically.

Also i have checked if laptop's keyboard is loose or anything... everything is fine on that side.

P.S.

Recently i have upgraded my 4+4 GB RAM to 4+8 GB RAM

this RAM is DDR3 and may not be original

 

Ctrl Alt Del, Vista

The whole Ctrl+Shift+Esc should be used to get that crazy screen with those options and Ctrl+Alt+Del should bring up TM.
