Why falling off the discrete graphics card on a laptop during the game?

Here's the situation. When playing dota2 (in other hadn't noticed) to a random point in time falls off the graphics card, that is, the image freezes but I can hear sound and can control the character. If you restart the computer, then in device Manager, discrete graphics cards and is visible as disconnected and if you open its properties, there is an error "now the device is not connected to the computer, code 45," and if after this reboot start DotA, it shows error "could not detect direct3d device". Tried shutting down the laptop and re-enabling it. The graphics card appears in the Manager in good condition and you can play. This happens under any Windows (7, 8.1, 10) and only in DotA, which is strange. Yes, the card is so-so, the old laptop, but for some reason in other games everything is fine. Drove formaram map, everything is fine. Was running a high fever, changed thermal paste and got down to reasonable limits. Also tried to play with different wood, - also to no avail.
Rummaged all Internet, I do not know what to do with it. Any ideas?

If after turning off the power on the laptop returns to normal, it is probably something with the bios settings (Windows 7 and 10 can change some bios settings, at least those associated with time; may be windows somehow conveys the right change the settings of the bois DotA...) bios Itself fresh? Try updating if not.

Well, the main idea is to put the driver on vidyahu from the manufacturer website of the laptop. And the only place to put them is necessary. Because the manufacturers are "rewritten" to fit your laptop. But on the other signs, in DotA you need settings grafone to reduce.
A lot of versions of fire wood sorted out - more than five for sure. Including from the site of ASUS, of course. In DotA, the dialogue is minimal, of course. And today again the problem in other games
Now I am scared that the problem is iron and it did not work - Aisha commented on April 19th 20 at 12:26
