Hello everybody, I'm from Buenos Aires City, Argentina I'm desperate. I don't know what to do. I've been having a lot problems with my laptop (Lenovo y560) since last thursday (February 13th). I don't know why, but, out of nowhere, random BSOD's have been appearing every single day since that day. They've occurred in different situations like, for example, while I was watching videos at youtube, reading posts in forums or just listening to music on my laptop. And all of them with different errors (e.g. page_fault_in_nonpaged_area; apc_index_mismatch; system_service_exception; memory_management; and some of them didn't have a name at all). The minidump files, that are supposed to be saved in order to understand the problem, just dissapear after a day. I don't know if that's supposed to happen. All of this started the same day I got an update from Windows. I don't know if that is what is causing my problems. I'll attache a couple of images of the updates from windows that appear in the control panel for that day. They are all for the 2010 office and those are the only ones that were updated on 02/13/14. There are a couple more from the office 2010 that were updated on 01/08/14 and one from the adobe reader that was updated on 02/04/14. The rest of them belongs to previous years. Oddly enough, I'm sure I've received another update after the first BSOD but it is not listed in the windows update list... Here is the description page of one of those updates: http://support.microsoft.com/kb/2837583 I recieve at least one BSOD per day. Only once I've received two (one in the morning and one at night). The last one I've receive was today, Februaru 18th at 6:00 p.m. (Argentina's time). and the name of that BSOD was "page_fault_in_nonpaged_area". Here I attache the .dmp file. When I get the BSOD, my laptop restarts itself (although in one ocation it turned itlself off) and ask me if i want to run windows normally or enter in the safe mod. If I choose to run Windows normally, the screen where I type my password goes black and I can't do anything. A couple of times the screen appeared but with some colours problems and it didn't let me do anything either. So I enter the safemode with networking. In there, windows tells me that "it has recovered from an unexpected error" (my windows is in spanish so please excuse me if I don't do the translation well) and asks me if it should look for a solution to the problem. I click in "search solution" but nothing happens. Sometime, it doesn't even give me that message. Still, I'm able to use most of my computer, so I don't think is a temperature problem. But I'm not allowed to use the Office. It says that it needs to intall somethings but an error always occure during the instalation and the application just shut down (all this in safemode with networking). After a couple of minutes in the safemode, I restart my laptop and everything is back to normal again. So that's what I do to fix the problem at the moment: I enter safemode with networking, I click "search solution" even if nothing happens, wait some minutes, sometimes I schedule a "comprobation for errors" (again, excuse my translations) in C/:--->properties--->tools (and I abort it when it starts when I restart because it takes too long and nothing changes), and restart (or turn off and then turn on) my laptop and the problem is gone until the next time. A friend of mine told me that I can restore the system until te point where all this started. i'll attache an image of that. Should I do it? Please, Can somebody help me? I really suck with computers Thanks to anybody that take some time to read my problem.
