Toshiba Qosmio NVidia GPU Problem

Hi everyone,

I have Toshiba Qosmio X775-Q7270 with NVIDIA GeForce GTX 560M onboard. Got laptop a year ago, worked fine 'till yesterday. I opened up my laptop, it recovered from sleep mode, and once I started typing in my account password Blue Screen Of Death (BSOD) breaks in, with the stuff written to which I didn't pay much attention. So I restarted my computer as prompted, decided to play DiRT 3, and to my shock the framerate went down from usual 40-60 FPS in all high to something like 10 FPS. I though it was maybe my old Nvidia driver ver. 290.53 going crazy, which I only keep because it has no weird graphics glitches in Battlefield 3 that occur in higher driver versions. So I decided to give a try for a new driver ver.310.54, but on the install it tells me that it could not find compatible hardware. In depressing state I go to NVidia control panel to only find out that "An NVidia Graphics card was not detected in your system". I tried using System Restore and fall back to the configuration of 2 day before the incident happened, but it didn't help.

Then I went to Device Manager->Display Adapters to find out that NVidia 560m was gone from there. I then checked the "Show Hidden Devices" box in "View", and now I can see NVidia in the list, but it is greyed out - "Currently, this hardware device is not connected to the computer. (Code 45)."

Does it mean that my GPU has passed away? May it have overheated (which is not quite possible, as I frequently use cooling pad while playing games). Something inside messed up? Or is just a system fault?

Any help is appreciated.

 

Wow, the problem got fixed by itself, didn't touch my laptop for a while, it stayed in a cool place. On one of the reboots the card appeared back.

 

Glad to hear you got it working, but sorry that we weren't able to help you.

Keep us informed if anything else occurs.
