BSOD after restarting from sleeping (NVIDIA hardware dissapeared too)
Hello.
I've got a qosmio x770 model PSBY5U (Windows7, 64bits) and suddenly I've noticed that my nvidia hardware (GTX560M) was not listed in the device manager lists. Before I've noticed, I've got some BSOD (most of them, after coming back from "sleeping" mode).
First thing I thought about, the driver. Looked for the most updated driver and it couldn’t find any hardware to work with. So I restored the whole system back to factory conditions and installed the original driver. So far it was all good and back to normal but after I installed all my software back and after several rebooting, the nvidia was gone again and after sleeping and starting again the laptop, another BSOD
I decided on restoring the qosmio to it's total factory state again, did everything all over again (drivers and stuff, without non critical software), worked just fine and after several normal shut downs, the nvidia hardware disappeared again, and so on.
The curious thing is that after several days, I tried to reinstall the nvidia driver, and suddenly I could, the hardware was indeed recognized, but whenever a BSOD happens, the hardware is no longer visible nor recognizable, so I'm really confused on what's going on, if it is just software problem or if it is a hardware problem.
By the way, when my nvidia stops working, the "eco utility" for power saving while working with battery, doesn't work. It looks activated but drains my 3.5h battery in 1.3h but when the nvidia is "working" everything gets back to normal.
Thank you in advance for your help.
