On my Toshiba Satellite A205-S5812 I am having a few problems on start up. Whenever I turn on my computer the first problem is that it always like reboots itself sort of and then recommends using start up repair. I barely do this because I have tried it and whenever I start up it will just ask to do it again. So I start Windows normally and then when I log onto my username a little box pops up that says "Warning: Your system does not support hibernation." If I can remember, my system did support hibernation but I am not 100% positive becayse I have never needed to use it so I wouldn't know if it went missing. Anyways, is there a way that I can stop this from popping up and maybe even get my hibernation back?
