OK, Here's my story. PLEASE respond if you can give me some help. A couple months ago I installed a Matrix Modchip with EvoX 2.5 in my X-Box. Today, I received some backup games. I put the backup Halo in and it didn't work. So I opened up my X-Box and re-aligned the chip, but I didn't put the X-Box back together. I put in Halo and it worked. I also played a couple of other games and they worked too. Finally, I put the X-box back together and the games started not to work. I opened up my X-box again and tried to re-align the chip. Still, the games wouldn't work. So, I decided to take out the chip. Now, the X-box won't even turn on. I think it might be the power supple, but I don't really know. Please respond or e-mail me if you can help.

Thanks.

Did you check all of your cable connections to make sure none of them were loose? Also you said "it did not work" what exactly did it do?
