Acer aspire 5742 shuts down after 2 seconds

My Acer Aspire 5742 shuts down, loses power 5 - 25 seconds after powering on. :(
It started when I was playing a video game and the laptop suddenly shut down. I thought it was overheating, so I let it cool down. About an hour later I turned it on and it boot normally, but 45 min. later the laptop shut down again. Next time I tried, it turned off 20, 5 minutes, then 30, 20 seconds later. In those 20 s after pressing the power button no errors or beeps occur, just the Acer logo screen. I even get past Acer logo sometimes or go to Bios password prompt if i press F2, just before laptop powers off. This all happened in the course of a few hours, laptop was working fine beforehand, no overheating (think so cause games lagged when laptop was overheating previously). If I turn it on again, just after it powered off, the laptop shuts down in 7 seconds, as opposed to 25 seconds if i leave it alone for a while. Also, according to task manager CPU and RAM usage is normal when shut down happens.

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
