Troubles with installing the AMD display driver (Windows Kernel Security Check Error)

I'm trying to install the AMD driver for my graphics card. The installation almost completes but as soon as the system switches to the new driver, I get a screen full of blue noise and the system reboots. After this the system will permanently reboot straight into a KernelSecurityCheck-Error.

To fix this I need to boot into save mode once and deinstall the driver. After that, Windows boots normally again, but will be using "mircrosoft basic display driver" instead.

When I try to install the display driver in safe mode, I get a driver signature error, which is very weird.

I'm using Windows 8.1 Pro and the Graphics Card is a R9 270x. I haven't bothered with games yet, but the card(default driver) is driving the display without problems (videos and such). Never had any troubles with the card before this incident,random crashes or artifacts and such. However, the OS is fresh, since I had to switch to a new motherboard recently.

I'm worried, that there might be a hardware problem. What do you guys suggest?

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
