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? Also - Fixed the instant shutdown. Bad wire management.

Also. I am using a hard drive from another computer. While my partner is certain this might not be the issue, I am almost damn sure it is. Sadly, I cannot connect it to any other computer in my household to remove the information from it. Might that be it?

And removing removing, then placing the CMOS back in tends to help..Not everytime though.
