I just bought a ps3 slim since my old 1 died but i can't seem to register it online since i wasn't sure if i inputted the serial and model number correctly though i think i did but it kept saying invalid x_X what gives...

Yeah i will be doing that but apparently i have a new problem now. It seems the ps3 seems to keep flickering/blinking at the xmb. I'm not really sure whether is my monitor issue, the cable or the ps3 itself. My monitor can support 1080 resolution and i was using a hdmi cable to connect to it. I have double checked everything though i have not tested it on another lcd screen nor another hdmi cable but im really hoping that is not the ps3's gpu thats faulty.

I did read about it in alot of playstation forums and its apparently about HDCP handshake issue but i don't understand it works alright on my old fat ps3 as it was able to go full HD.

Apparently it was my hdmi cable that was the culprit. Anyways, it seems when i turn Deep Color feature, i will get the rainbow pixels around the screen.
