Hi Guys
I'm having a strange issue with an Acer Aspire A515-51G-737T....The Keyboard of the laptop worked fine when later some of the keyboard buttons/keys did no longer work.
So i Got a USB Keyboard to work on and then later on the mouse pad of the laptop started to get laggy and struggles to work.
So i got an USB Mouse and the same thing appears with the mouse as well.
What i have tried is=
Reinstall Mouse and Keyboard drivers.
Downloaded new Drivers from the original Laptop manufactured Website.

In Device manager everything shows its working BUT i have later discover that in BIOS some of the keys still don't work...So i don't know if it could be the Laptop itself that's having issues or just the Software.
Specs=
Intel Core i7-7500U 2.7 with turbo boost up to 3.5
Nvidia Geforce 940MX with 2GB Dedicated VRAM
4GB DDR4 Memory
1000 GB HHD

Can someone Give me other suggestions on how to FIX this problem...It would really be appreciated.
