Hi. For the past several weeks I have been having serious problems with my Lenovo Y570 laptop that have been getting progressively worse. The problems started when the computer began to fail to hibernate. Sometimes it would successfully hibernate, other times it would hang with very high fan/cpu activity, and have to be manually powered down. If left in this state, the system eventually restarts on its own and on reboot I get the message about Windows failing to shut down correctly. At first this was occuring only infrequently but now it happens everytime I try to hibernate the computer. I have also encountered issues when closing the screen or when the computer goes to sleep (failure to return from sleep, random restarts, etc.) I have now been starting to encounter other startup/shutdown problems frequently. For example, the system will lockup on the Windows logo screen, or at the bios screen, and have to be restarted. These problems seem to be worse after a failed hibernation when I have had to kill the power. Typically after a few tries I can get into windows, although sometimes I have had to preforms startup recovery (which just does a system restore). Once in windows, the system seems stable. I have worked on it all day and/or left it on overnight without problems, as long as power is not interupted. I have also had several BSODs. Most recently, this occured at the user login screen, before I had a chance to type my password. Event viewer gives the following information:
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000124 (0x0000000000000000, 0xfffffa80084c3028, 0x00000000be000000, 0x0000000000800400). A dump was saved in: C:\windows\MEMORY.DMP. Report Id: 120814-26067-01.
At this point I am pretty sure all these problems are related somehow but since they are so various I'm not sure how to proceed in diagnosing/fixing the root cause. Any help would be very much appreciated. Thanks!
