No video on TV - New system

[Fibonacci_37]

Hello. I have built a new computer, and am trying to get it to work. I've been trying for well over a week. If it isn't shutting down to prevent itself from frying as soon as I turn it on, then it won't show squat on my TV, I only see a black flicker every few seconds. I am using a radeon HD 6770, and my TV is a RCA 32 in. LCD tv ( 1366 x 768 ). Any help would be appreciated, I have never used this site to ask a question, but I have looked at it from time to time to gather information, and I must say this is the leading source of answers of anything related to tech. I will be checking back very often, any help would be appreciated.

Note - I got it to work after removed the CMOS(?) but this happens ALOT - I am new to PC building and have liked screwed something up massively. Any tips? Help?

Am also using a harddrive from other computer, which I know is bad. But my comp won't even display image, so I don't even know if it's entering BIOS. I do get it to show up occasionally, and when it does, I can enter bios and etc.

And it seems to be getting hung up on MemOk!, with continuous flashing. Or no light whatsoever. Green LED is on, letting me know there's power to it. I have to shut it down through the PSU on the back, because the front buttons will not respond whatsoever. My screen just flickers occasionally like it is trying to do it, but cannot. I have been checking this site over the last week, and I have taken the steps, like taking out of case, stripping it bard, carboard, etc. I got it to work recently but I swapped harddrives and got a system crash message, asked me to restart, no image again. It has happened before this.

Bump. Am quite desperate here, and very new to it. Will continue to bump until scolded or advise offered.
