DisplayPort gives me a black screen, but HDMI works?

So I just got an AMD Radeon R7 360 to use on my new HP 27S Envy monitor and am having an issue

it's identical to this, i think, which was unanswered: http://ift.tt/1f8b5L5

If I plug the DisplayPort in, i get a black screen. If I plug in HDMI, it works (but is 30hz, so no bueno). When I boot, I can get bios and the windows logo, but once 'Windows' finally actually loads, it goes black.

I can swap into hdmi and immediately get picture, but I need the DP to work to get 4k@60 running

Any ideas?

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
