Hi guys, I'm new here in this forum. I just wanna if you encountered this one.
My xbox360 slim has no problem with power connection, it turns on but it does not boot to any dashboard even the xbox dashboard that I know will boot without any external hdd with fsd/xexmenu. So please help me. How do I fix this problem.
Thanks in advance. Cheers!

Please fill out the template. There isnt enough information to tell u what the problem is. Does the system start without any HDD attached? Have you gotten the CPU key?
