Q: my laptop is Lenovo Y450A-TSI, recently when I watched video, it always shows blue screen and then auto restarts. When playing games, it would have blurry screen symptom, even after reinstalling operation system, the problem still could not be solve, then please help to solve the problem, thank you so much!
A: from your description, probably there’s something wrong with the display system, you might try updating the display card driver, check whether it could be solved. No need to stand on the manufacturer driver, Lenovo laptop could use NVIDIA public version of driver. Besides, you need to pay attention to the heat radiation problem, suggest doing some cleaning job to the machine internally; if the problem is still not solved, then probably it’s the problem of the display memory. This machine should be still within the quality warrant time. If you cannot handle by yourself, you’d better to send to repair in time, in case some unnecessary problem happens.
