I am trying to fix this laptop for my sister who really needs it for college. I am about to go crazy over this thing. I bought her the toshiba satellite p75-a7200 less then 1 year ago. Past 2 months, she would get a BSOD every once in awhile. I returned it to bestbuy and toshiba and they told me it was just a bad windows installation and it just needs to be reformatted (took 1 month just to tell me this.) They returned the laptop to me with no windows 8 installed, so I am here trying to install a fresh windows 8. I disabled the correct settings in bio's to get the cd or usb to boot. Once the windows 8 logo pops up, it sits there for a little less then 1min and then I get a BSOD saying at the bottom Machine_Check_Exception. Not sure what that means, or what is wrong. Did bestbuy and toshiba lie to me?
