HELP! I black screen after load, I'm only making it worse.

edit

So I updated last night to Fedora 21 Rawhide.

After the extremely long update, Fedora began to load. It finished loading and then went to a blank screen. (I am running amd 64bit).

I got into the terminal, and tried to delete some stuff assuming it installed a video driver that my computer wasnt happy with. So then I managed to delete a bunch of stuff that I regretted doing after I woke up this morning. - I think I removed almost everything I could...

The only thing I have currently is: Fedora, with linux -0rescue-ae6d340ad4a34e22861a6db9bd76c9b5 as a selection. I don't have an option for Rawhide, not do I have an option for Heisenbug (I think it's called?).

So I am basically screwed. I have messed up my computer before and managed to pull out of it. But my mindset with this problem is that if I can manage to update everything: Yum, kernels, FEDORA - I will be able to get my computer back. - I cannot connect to the internet though, through terminal. I keep getting error messages when I try to install or update anything like this (Error: Cannot find a valid baseurl for repo:)

I was playing around with 'cd' and noticed that my files and everything are still there, so it seems like its a visual issue. and looks to me like there is a way I can be saved from this catastrophy.

On another note. I have a seperate computer running 32bit Fedora 20, and it works like a dream. Compared to my new computer (which is the one with all the issues). The new one runs horribly. It has been nothing but constant issues, screen freezez, delays, things not working, extreme nasty lag when I try to turn the volume up and down. Or my favorite is that if I am watching video (youtube, or a gif, or even an ad with motion pops up) and I try to click on activities in the top left. My entire desktop becomes unclickable and I need to shut down programs in order to get it to work again. - If I can fix where I'm currently at, is anyone familiar with that issue and maybe can help out with fixing that?

Anyways, thanks for letting me vent. Please help.

When I try to do a 'yum update' or anything along the lines this is the screen that pops up and I don't know what it means.

1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distrobution release than is supported by the repository (and the packages for the previous distrobution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid></repoid ...
