Ok,recently, everytime I tried and load up my minecraft launcher, my computer starts messing up- programs stop responding, flash typically crashes, and there's massive slowdown. At the end of all of this, typically 1-2 minutes later, the minecraft launcher loads and the bugs stop. There are no problems when I'm playing minecraft itself. The problem still persists when i get a new .minecraft, and when I re download the launcher or get new ones (e.g, technic pack) the problem still persists.Can anyone help? I'm running windows 7.
There are various threads here where people recommend boosting the amount of memory that MC will use.
Your symptoms can be caused by that.
Basically when Java starts up it needs to allocate memory, and if your PC has little free memory, this kind of sluggish start up can happen.
By default MC will try to start with ~ 750MB of memory, but if you've tinkered with the memory settings it could be trying to get multiple GBs.
