Heres what I found..... https://www.newegg.com/Product/ProductLi... on that site there are SSDs that are cheap you can look for what you want what size what price your wanting to spend and everything. Hope this helps.
That could be a cable just needing reseated. It could also be what cameron said and it could be needing a whole screen. If you can not open the computer up to check the cable then follow cameron steps. It could be that simple though just reseat the Display cable. Hope this helps.
I think the error you might be getting is caused from the Date being off on your computer. Thats what I have found it to be several times while trying a reinstall or a fresh install of an OS. I would boot up into the installer and then use the Terminal command. If you would go to the Terminal and then type in Date to see if it is the right date set on your computer that will help you figure out if you need to change it or not you can find instructional videos online to help you with changing it if you need to. Say you type in the date and it comes back with July 5 2001 you wont be able to install Sierra because the computer thinks it hasn't come out yet. I tried to leave the instructions on how to do it here but I was marked as Spam..
I do believe it could be an issue with the Logic Board being that so many different things are being affected. If it were just the TrackPad and KeyBoard I would say perhaps a the IDP Cable which goes from your TrackPad to the Logic Board. But being you have so many other issues this fella up here saying Perhaps Liquid damage..?? Could be correct not saying you intentionally spilled liquid but it can happen heck I've seen a computer come in with Cat pee liquid damage and the customer had no idea. The only thing I would suggest doing if you open it up and it does show signs of Liquid would be to take it to the nearest Authorized Service Provider and have them look at it and perhaps give you a quote of a depot. Or you could send it off to a depot that we use called Micro Replay they will charge anywhere form $300-$650.. They will fix everything in the computer for you and they also give a year warranty on their work. Hope this helps in any way possible.
Do you have the Logic Board exposed on the iPhone? If so then Yeah I would get it covered a static charge could kill the Logic Board and it could easily be killed. If you have the Logic Board out and exposed then I would place it in an Antistatic Bag to preserve it chances are that if its been exposed for any type of long term its already been damaged in one way or the other. Hope that helps..
If this is a drive you have used on the same computer and it is not showing up now listen to the Drive and see if you can hear clicking coming from it or see if you hear it spinning. If its clicking then usually that means the Drive is about gone "Dead" if you can hear it spin then I would need to know what type of computer your on and what kind of Drive you have mounting.
Do you still have warranty on it? If so I would try contacting them and see if they can do something for it. In the meantime if you have a friend with an xbox one then try using their Power brick and see if it works that will rule out one or the other.
The only way I know how to go about it would be to put that computer in target disk mode and then erase the Drive then do a fresh install like it were a new drive. If you were just to try and install the OS El Capitan you wont be able to you'll always get the prohibitory sign. you could also take the Drive out of the computer and put it in a sled or you could access DiskUtility form the Sierra installer.
Have you tried a Hard Reset? Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Doing this might help. I would try this before doing a factory reset.
