So I got an asus windows 8 notebook about 6 months ago and it has had problems ever since I got it. It will freeze randomly, could be anywhere between 10 minutes and a few hours after startup and it will freeze. I will then restart it and sometimes it will freeze before I can even sign in. I have used system mechanic, windows defender and mcafee to see if it's virus related and every scan says it is fine. The motherboard is 1.8GHz intel core i5, the graphics card is nvidia GeForce 720m, 4GB ram (one stick), the psu is a portable laptop charger. I have no idea how to access the minidumps on windows 8 as it's the first windows 8 computer I have had. I do an online course so I really need it to stop freezing as it makes it difficult to study. Thankyou.
