The case is, it;s 50:50

sometimes it work, sometimes it doesn't
the problem is my monitor screen is just pitch black, but its not on a sleep mode, which means there is a connection, and i know my Firefox window is there, its just that i cant see due to the screen just show nothing but pitch black

but if it succeeded at the start up, then it's good to go

i doubt it's my HDMI cable as it is new, and i tried to play with with my PS3, and it works

it's like it as no power to transfer the HDMI to my monitor, which is weird, because im using GT520 nvidia card and i5

so i figure this is the OS problem not my hardware?

any fix on this?

thanks!
