Getting frequent crashes of all of my games.

[LX4]

It started on the 11th, when my dota randomly shut down mid game, I brushed it off then, but its been 4 days of this now and I haven't been able to solve it. I think I might run memtest just to check, anyway, about the crash itself: In dota, nothing happens, the game just closes, in borderlands 2, I get "Borderlands 2 has stopped working", same as CS:GO, I'll put the crash logs here too, thanks for any help!

Hmm, it seems like a faulty nvidia driver.
What graphics card are you using and what is the version of your driver?

After I posted I noticed the nvd3dum.dll trend... if that is what tipped you off. My card is a geforce 650 ti, and I've got the latest 320.49 driver for it, funny thing is, the driver has been installed since the third with no problems, then again I only just started playing BL2 on the 11th

Edit: just looked up that .dll, and it might be that I forgot to uninstall the old driver, before installing the new one, I'm rolling it back now.

Just reinstall the drivers and tick the "perform a clean install" checkbox.
And yes, that dll file tipped me off.

Also if that Dota 2 issue presists, try reinstalling directx.

After doing all of this I had no preoblems for about an hour in BL2, I'm pretty sure this fixed it, thanks very much! I'll have to play more to be certain though
