Hi Nikhil D
It was all grey and then welcome came on
It was all grey and then the welcome came on
I would like to know if you have tried the steps provided in the above post to uninstall and reinstall the video card drivers for the computer.
Please try the steps and post the results.
No I haven't . I shut the computer completely down for a couple of days and now it has not done it again ! Very strange
The problem could be with the video card of the computer, to isolate this please check the functionality of the laptop by connect an external monitor to the laptop and try using the laptop with an external monitor.
Please post the results.
I have the same problem with my 5520; with 7730m gpu. I'm suspecting the gpu there, as Catalyst Control Center could not switch to 7730m, when I play. (medium settings in World of Tanks with an average of 10fps doesn't seem that it uses a 7730m on a 8gb, i5 cpu system.)
I've already checked all the above solutions; LCD BIST is totally OK, reinstalled the latest driver, still poor performance during playin' (suspecting that system do not switch to the 7730m), and random blank screen during usage.
In Catalyst Center I can only see the Intel HD4000 as a gpu, no 7730m displayed at all! I don't know whether it is normal or not?
Should I take it back to the store and send it to a warranty repair?
