I keep getting kicked from every multiplayer server. I can play for about 4-5 minutes, then I 'time out'. There are 2 other desktops in my house besides my own and they experience no problems. Obviously, I think it is my computer although it used to run Minecraft perfectly. I have updated Java, checked firewalls, checked network connections, scanned for adware, spyware, viruses. We have a beefy router, recently bought. Is this a RAM issue? Did my RAM just 'fail' suddenly to cause this? I tried using a USB stick to 'add' RAM as a temporary solution, but I see no change. I have no other internet connection problems. Any suggestions would be much appreciated.
