Need help restoring a Laptop

[Shadowdiamond201]

My brother has a Dell latitude D800 that isnt too different from my old latitude D820 that I accidentally smashed. My brother has been having a lot of browser issues and complains that it can load slowly and when it does load the browser is missing photos and the text can be spread out and unorganized. he was wondering if i could help since the main thing he uses the laptop for is just surfing the internet and checking emails. he has also told me that the mouse acts on its own accord when he is typing and can travel from one end of the screen to the other without him ever touching it. The slowness i think i can help with a stick of RAM and the broken mouse seems to be keyboard issues and not software. so im wondering how do i fix his browser issues.

Try updating the WLAN adapter drivers

I feel like he kind of needs to manage his expectations from a computer that old. Even general browsing has gotten significantly more taxing than when that laptop first released (early 2000's?). I'm sure the mouse issue is his palm hitting the trackpad while he's typing, I don't think they had palm rejection back then. Why doesn't he try upgrading to something a little newer?

Wow, he’s actively using a system that old? That’s impressive. I have one of those laptops and it struggles to play videos, even DVD quality. I’d recommend just getting a used (but newer) laptop.

Thank you Crunchy Dragon. this seems to have fixed the browser problems so now all the text and stuff is there and working as it should. however,Theguywhobea is wrong about the mouse pad tracking because my brother just showed me the laptop and when I typed on the keyboard while being very carefull not to touch the mouse pad the mouse would dance across the screen. I also noticed he failed to mention to me that there is a line of dead pixels on the right of the screen that don't show any color. I am not sure how the mouse issues and dead pixels will affect too much since the mouse still works and stops dancing on the screen when you stop typing and the dead pixels only cover a small portion of the scroll bar.
