Hi,
Dell Vostro 3450 (Core i5 2410M, 4GB, 500GB, VGA 1GB AMD Radeon HD 6630M, 14 inch.
Unpredictably, my monitor goes black except for a brief message that there is no HDMI. Usually a cold boot is required to restart, then the system runs in a normal fashion.
The Event Viewer doesn't show any related events. System fans and power continue to run when the screen goes black. I presume it's the video card, but before I throw a couple of hundred dollars at the problem, I'd like to know how to check if it might be something else.
Also...what mid-range cards do you folks like for desktop and mid-range (non-twitch?) gaming? I play a lot of Witcher 3 for example-- and the video card performs adequately.
Thanks very much.
