Q:

On Boot: Random colors flashing in jagged formation then nothing

I am using Raspbian 2013-07-26 and I have been having a lot of trouble with my Pi lately (cheap SD card I'm thinking, lots of corrupt stuff). 
Anyways, when I try to boot it I get this on the screen (lines are more angular on screen, it's somewhat distorted because it's a picture of a screen:

and then it goes to staticy nothing. 
I really hope I haven't nuked my Pi, but it looks that way, at least the RCA adapter. I can connect and do everything via the USB Console cable I have, but I don't get any graphics on my screen. 
I did add some files via my MicroSD card reader (MicroSD slides into slot on the reader which goes to USB) right before the problems began. I have never used the reader before, so I don't know if this is unusual.
I haven't tried HDMI yet, but I will as soon as I can. I have re-imaged my SD card since this problem started using the same afore-mentioned SD card reader. I will try re-imaging with the MicroSD Card adapter (MicroSD to SD) in my SD card reader to see if that solves the problem.
Have I fried my RCA Video somehow, or is this because of something internal?
Please help, I really like my Raspberry Pi and don't want to have to pay for a new one.
Edit: I re-imaged using the MicroSD Card adapter (MicroSD to SD) and same problem. 

A:

Well, I don't why, but after letting it sit all night, it works again. Thanks for the help @Milliways, but it solved itself. 
I'm thinking something might have tripped the F3 polyfuse as several of the components were really hot, including the fuse (as in burning my skin hot for the fuse).
