PS3 Slim locking up when using browser and sometimes PSN

[Euphoria14]

Does this happen to anyone else?

If I use the browser the PS3 ends up crashing and needs me to hold the power button for a long time before it goes off.

 

I also downloaded something from the store earlier and it also locked up on me. It also goes very slow.

 

 

I can usually play games online though although sometimes in KZ3 it says "Lost connection with Game Master" and take a long time sometimes to jump into games.

 

My connection is about 7MB/s or something like that right now.
