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+SHIFT keyboard combos not working

I've been using Windows 10 at home for a couple years. I use numerous keyboard combinations that involve CTRL+SHIFT. For example:

• CTRL+SHIFT+V to paste text without formatting
  
• CTRL+SHIFT+T to reopen a closed tab in Google Chrome
  
• CTRL+SHIFT+E to export photos in Adobe Lightroom
  

And so on.

My problem is that all CTRL+SHIFT keyboard combos stopped working. I don't know how or why! Suddenly one day they didn't work any more. Whenever I press CTRL and SHIFT at the same time, I get a beep, and the desired combinations don't do anything at all. This problem persisted for more than six months. I tried everything I could think of, researched many forums and message boards. Nothing worked! I gave up and learned to live without it, though I was quite frustrated.

Two weeks ago I noticed the functionality had returned. CTRL+SHIFT keyboard combos worked again! No more beeps! What changed? I don't know. I enjoyed using these shortcuts again, until about an hour ago when they stopped working again and the beeps returned.

And here's the kicker: midway through drafting this post, the problem once again went away. CTRL+SHIFT is working again. Hooray. But for how long?

I strongly suspect that I'm inadvertently turning some setting on and off. Can somebody please tell me what or how? This is kind of driving me crazy, and I don't want to be at the mercy of my own stupidity any longer. I can't be the only person having this problem, can I?

 

My left ctrl key stopped working, and the right ctrl key is pressing both keys

Hello fellow members, so I recently bought a new keyboard because I got a gaming PC, and probably 2 weeks into using this keyboard, during gameplay. the left ctrl key for some reason stopped working, and all of a sudden both ctrl keys were being pressed
at the same time (and it didn't stop), I don't know what happened but that problem is gone, but the left ctrl key is still not working, and I found out that the right ctrl is simultaneously the left ctrl key, I don't get it, please help me if you can people,
thank you so much.
