Strange lag/delay (every action happens 60 seconds later)

[Kungen]

Now and then I start to lag, I don't disconnect and I can still play but whatever command I use it comes 60 seconds later, so I basically die everytime since I solo in deep down in dungeons. Gchat, spells, con all happens with a minute delayed.

Everytime I gotta alt F4 and then I usually start dead. Getting old
