Raspberry Pi Pinprick / Faint Green LED and Red LED

I have spent nearly 2 weeks wondering why my raspberry pi would not boot, i tried different SD cards, diffferent power supplies and everything. I just kept getting a red LED with basically no green led (or as some people put it, pinprick green led).
I tried using the alternate boot files from github which some people reccommended for class 10 SD cards, and still no luck.
I tried using rasbian, xbmc and the android release with no luck, until this morning i decided to give it one last go and try arch linux.

Hurrah! It booted, now i have use of my pi again!
