Wii not loading DVD

Hello,

I've bought a wii. There is a chip in it.no bootmii, no priloader.
I have made an update and format the console.
Now i'm in 4.3E.
When I launch a game, i've a black screen.
When I click on other channel (mii, photo, ...), wii restart.
I saw the icon of the backup when i put a backup dvd but also have a black screen when I launch it.

When I format the console and put wii party i can make an update but after that still have the same symptoms.

Any idea to solve this problem?

Thanks in advance.

you probably screwed up by installing DARKCORP. Uninstall it if you can

how to do this?

DO you play your "Backups" through the disc channel?

when i launch backup , i have black screen through disc channel. I see icon of rhe backup only.

No one cares about your failure to load "backups". Come back when you can't load purchased games. (Probably soon if you're messing with your wii trying to run "backups").
