7'' amlogic a9 android 2.2 problem

[rainbringer]

Hello,

I've bought a new 7'' amlogic a9 android 2.2 and I've two major problems with it:
1. It sporadically reboots once in 10-15 minutes.
2. I can't browse the web because the browser shuts down (I'm thrown back to desktop) about once in a minute.

What can be the problem? Hardware? Software? How can it be solved?

Thanks!
