Hey guys. Not so long ago I built a computer with the help of computerhope. Everything was going well, until I noticed that my computer crashes. A lot. I'm on windows 8.1, I used to get the "Windows has ran out of memory" which happened to be a problem with the ram, I quickly fixed It though, it wasnt a hardware thing. Now I'm getting a lot more errors, tons of blue screens of death as well, like "Ntfs error". Aside from my computer crashing, other softwares do too. Like Firefox, Google Chrome, Guild Wars 2, My Anti-virus, VLC player (although that could just be the fact that windows 8 is funky). Also, i dont have a wireless card on my computer, so its connected to an ethernet cable. The problem is that whenever the cable gets detached, my computer cant connect to the internet when i reattach it, unless i reboot the computer. Sometimes it just randomly disconnects. Help?
