FPS drops that are fixed by disabling Windows Defender real-time protection

Windows 10, i5-4460, GTX 970

I've been having fps drops in my games for a few months now (Rainbow Six Siege, PUBG, Vermintide 2 to name a few) and I couldn't diagnose the problem. Then one day a couple weeks ago I realised Antimalware Service Executable (Windows Defender Antivirus Service) was using about 1-2GB of ram in the task manager. After disabling real-time protection in the Windows Defender Security Centre, I realised all the fps drop problems in my games were gone. Since then, I've been having to disable windows defender before I play any games, since it re-enables itself every now and then, even during games which is noticeable immediately as the frame drops start straight away. Now my question is, why is this happening, as windows defender is no longer using crazy resources, but if it is on, I get frame drops. I don't want to disable windows defender permanently, I just want to diagnose and fix the problem.

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
