I bought this windows 10 computer the first day it came out. Haven't had any problems with it until today. I woke it from sleeping and it gave me the BSOD and said it had to restart. It showed me a code of hiber_iastor.sys I'm not a computer guy. I use it for emails and radio operations/programs. I read the info on how to post up and what to add to the post but when I tried to DL the W7F program my computer said the file was corrupted and had to restart. So no files to add on this post. Anyone know anything about this hiber_iastor,sys thing. I do good to open email so system things I don't play with. Don't know the difference between bios and registery so now you know my experience. Any help would be appreciated. BTW, My spelling sucks too. ha. This is a Dell computer that came with windows 10 on it. It has 2TB of something and 12gb of something else. Memory and harddrive? Don't know one from the other or wich is which. I've used very little of its abilitys as far as each of these. No movies or odd programs downloaded to it. Onlt the stuff I've used on the last two other computers I've had in the past. Hope this helps.
