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.

Thank you for your response.

The strange thing in here is that I bought this lap one year ago, and I just got this problem like 1 month ago. What would have been the cause of this? I haven’t mess up with the lap nor with software, just normal and smooth operation.

If I do a clean re-install, will I lose the "factory partition"? I mean, will I ever be able to restore the machine to its original factory state after clean re-install?


Thanks,

I guess so.

Are these my only options? I ask this because it's a pain in the ass looking for all the drivers I will need after a clean re-installation (touchpad, speakears, webcam, bluetooth, blueray dvd....etc etc), so, that's the deal? Just those options?

Btw, as you can see, I'm not an expert in hardware-software, you knew it was a ACPI reated issue becauseof the dump files?

Thanks, regards

Then take the last option, go to the vendor and ask for a replacement :)

Yes, a stop 0x9F is mostly a ACPI related issue, but when it is associated with a PCI/PCIe device, it is comparatively hard to troubleshoot. Lots of trials and errors are needed to attain at the desired results; and power saving bloatware like Eco Utility makes the job even harder.

Ok, I guess I will use the warranty extention I joust bought 1 day before its expiration date lol ......Thanks a lot.

So, (I'd like to know a little bit more of this...I'm just curious...) is it a hardware failure finally? I mean, if I wouldn't have any warranty and take this to any workshop for repairs, what should be changed?Just software, the nvidia card or they will just tell me to throw thelap into the garbage?

Thanks, regards!

No, its not a Hardware failure. It's an ACPI related issue mixed up with some bloatware, which is making the hardware fail.

After cutting out the bloatware and adjusting the Sleep/hibernate/power plan settings, the laptop should run fine (provided there is not any hardware error; we haven't checked, and there was no real need to check as per the data).

so evrything is connected? the nvidia card, the bloatware and the operating system-power settings?
