help! many problems help

[trippx]

Hey. I was wondering if someone more knowledgeable about pcs would help me out. I've got a problem with my laptop. (It's a HP ProBook 650, originally on Win8Pro.) I put my own copy of Windows on it which is Windows 10 Pro (I think the problem is maybe in the Windows.) I have an i5-4200M 2.5GHz integrated graphics, 4gb of ram. (I'm sorry for any grammar mistakes, english is not my main language)

 

Problem 1: The keyboard on the laptop is weird. It doesn't look ilke there was any contact with water or any other liquid. The keys are like on a normal keyboard, they are not sticky etc. The keyboard works (sort of) because sometimes it works perfectly with every key working or now only half of the keyboard works (the keys a,b,l,n don't work but sometimes they work normally) sometimes like on the number 1 on the numpad it always types 18 except of 1. External keyboards work fine but it isn't practical carrying one around always. 

 

Problem 2: Everytime I turn on my laptop the Wifi works for 2 seconds while I'm still in the lock screen and then I see the Wifi icon turn off. When I unlock my laptop the wifi is turned off, when I try to turn it on I have about 10seconds to connect to a wifi network otherwise the wifi on my laptop will turn off and I have to try again, sometimes it isn't a problem but sometimes I have to turn the wifi on and try multiple times.

 

Problem 3: I have all of the Windows Update settings turned off and still it just pops up the blue windows which says "You need to donwnload these updates" with no way to close it only by clicking "show updates" then it opens the settings and when I close the settings it doesn't pop up anymore until I put the laptop to sleep mode (I close the screen) and open it back up, it usually happens about 5 minutes after i turn the laptop on.

I would try booting something like Ubuntu just to see if the hardware related issues are really the hardware or if it's something going on with the new Windows install.
