Did my Mincraft crashed? Or is it my gadget I need to repair?

So I have this 20+ mb world in Minecraft, then it started lagging. I restarted my tablet several times but to no avail. I updated it to the latest and the condition got worst. Everyhing is blue and I can't do anything but walk. Is there something wrong with the PE version? Or ia it my tablet I should repair?

In the market for a pre-built gaming desktop?

In about the $500 range (i'd say about 400-600). Now, it doesn't have to play Battlefield 4 at max settings with 150 fps. I'm just looking for a pc that will play just about anything at medium settings with little to no lag. Games I know i'll be playing that come to mind are Minecraft, DayZ, Killing Floor. I doubt i'll be playing things like Call of Duty or Assasin's Creed.
I know next to nothing about this sort of stuff, so I need it to be pre-built, playable right out of the box, and in that price range (if there's really nothing that works like this then of course i'll go higher, but obviously I want it as cheap as possible).
*Oh and preferably have Windows 7*
Right now I was looking at this one: http://www.amazon.com/...00D1KX2M4/

Thoughts? Suggestions?

Why isn't my minecraft working? - 2

I just started up my computer and when I went to use minecraft, suddenly the icon just glowed and the white little border around the icon disappeared and the game never turned on, this went on for 2 hours as I was waiting for it to turn on by watching tv shows. So that is when I decided to reinstall it and when that happened, the game still didn't turn on. Please answer soon, thank you.

Trouble with hardwired connection to a Netgear n600 dual band adapter?

Trying to play minecraft with wife and son. You must connect via LAN. 2 computers are hardwired and one is connected via Wi-Fi.

The hardwired PC's are marked as being on different networks even though its the SAME router!

one is netgear and the other is netgear-5g (the 5g connection). Again, please recall these are not connected wirelessly…

How do I tell the PC to ignore the 5g connection?

Minecraft Optifine 1.8 won't open properly?
