Dark screen and slightly blurry

I have had my x3 fitted for a while now but today my screen has gone dark and slightly blurry, enough to put me off wanting to use it. Also when i load a game, whether the chip is on or off, I get a little glitch type screen just before it loads with like a bar code at the bottom center. Has anyone come across this problem before and know whats wrong?

I have a bit more info now

I have since reflashed my chip, installed all my software again i.e dash boards , apps etc. The box is fine when I boot it up, the x3 config live screen is nice and clear, i can boot to the evox dash and thats nice and clear, if i run any apps they too look fine but as soon as I load a game up the screen glitches sometimes half the screen goes balck and flickersm and then the dark screen kicks in :-(
Could it be the dvd drive or am I clutching at straws now :?

Also one last thing, my bios comes up with 'unknown'. Is that right?
