Laptop Graphics Card sometimes missing.

[gauravweb]

Hi,

I have Samsung NP300E5Z-S0AIN (Intel Core i3, 4 GB DDR-3 RAM, 750 GB HDD, Nvidia GeForce GT 520 MX 1 GB Graphics Card). Sometimes my graphics card is not detected by my system. It does not show in device manager. I have attached some snapshot. How should I fix this.

That video card is famous for driver issues.
maybe try to update to the lastest drivers.

I have already tried the latest driver. But when the Card is not listed in Device Manager the driver installation window says No Supported Device Found

Sounds like the GPU may be starting to fail.....
I would run a program like Checkit ( http/checkit-diagnostics.software.informer.com/ )
and run the Video tests....

I have an update. Previously my TouchPad was not working fine. The touchpad works fine when I start my laptop but after 15-20 mins it does not work as expected. So I started using a wireless mouse. Recently for some reasons I was using wired mouse and I found that the wired mouse is also not working properly. So I changed the mouse and it was still happening with the other one. Somehow I noticed that the same mouse is working fine when I operate my laptop on battery (i.e. without the charger). Whenever I connect the charger mouse started acting funny. However I does not happen with wireless mouse. I am clueless on this. But while experimenting with all this I also noticed that when I turn on the Laptop without the Charger, graphics card is listed in device manager and still remains when I connect the charger. However after a 30-45 mins (charger is still connected) my laptop crashes with blue screen. Is it possible that my laptop is facing some power issues ?

it's definitely a possibility. Sounds like you definitely have a hardware related issue somewhere. it could be a short, could be a faulty charger. It might be a good idea to take it to a repair technician to run some diagnostic tests, unless you have the equipment to test your own hardware.

I live in a pretty backward are where I dont expect any technician to have knowledge to execute such tests. Please suggest me the hardware required and "how to" about the same.
