Screen flickering on my VAIO laptop (OS is Windows 10)

My model is Sony Vaio SV15139CJS Video card: Intel HD Graphics 4000 Sometimes randomly my screen starts to flicker and it is a really annoying problem because pink lines start to appear on my screen and it becomes impossible to use, the screen becomes practically unresponsive. I have tried downgrading and updating my video card driver and the problems seems unrelated to that. This problem occured once even when I was using the Windows's safe mode. When connected to external screens, the external screens respond perfectly with no problem. Is it a hardware problem? If yes, would it be costy to fix it?

Thank you so much, I need my computer to study and I beg for your help.

certain keys on my keyboard dont work when "cold"

Hi guys, i have a Lenovo Y520-15IKBN (80WK) and certain keys on the keyboard don't work (e,g,h,8,9,Fn...) but only when the weather is cold. for example in the winter it used to work after certain amount of time when i first boot the laptop and stops working when i stop using it for a while, but now that the weather is hot it works just fine except for the first couple of minutes or when its colder. of course i do realise that it has nothing to do with the outside weather but with the temperature of the computer itself. can someone explain to me why this is happening and how it should be fixed as i cannot take it to the tech service until july even though it's still under warranty because i need it for school. ps: an external keyboard works fine.

Old PC with a Foxconn n15235 motherboard needs drivers! Help!!

So my Pc corrupted and I had to fresh install windows on it, but now its missing 3 drivers and one of them is for the Ethernet controller! I've tried searching everywhere for the windows 7 drivers but all I seem to find are some dodgey programs saying they will install it for me. Problem is without the ethernet driver I can't bloody connect to the internet. I've been using a USB to try get some drivers on there, but they just end up being useless programmes . I'm also a bit of a noob at these things, I don't understand where to find the names of things in my PC, I've opened it up but I don't understand whats significant and what isnt. If someone has the drivers and can teach me how to install them I'd be very appreciative! Submitted April 29, 2018 at 02:47PM by darrilsteady https://ift.tt/2r76xMZ
