Hello, sorry i bother with this, a bit older hardware, but its still doin good for me. I have a problem, that someone may give me some tips or advice. Recently with newest drivers from nvidia (337.88), my graphic card gone crazy, flickering, crushing driver. Ive tried to reroll older driver(s), even few of them even when i roll driver that was runin for like a 6months goin crazy, so now nothing works as it should be. (I run my machine on 16gigs of ram, i5 760, win8.1 enterprise). Then I realized fans are really quiet on graphic, i've downloaded expert tool for OC from gainward, and only what i did is give a little boost to fan's speed. and its working perfectly. Now everyday... even on desktop if fans on graphic are not started, nvidia driver is crushing. its not overheating since its not working only desktop mode IDLE and when i check tempreture, its 33 degrees celzius on gpu. Any advice how to fix this, or OC expert tool is only solution ? Thanx in advance for all answers.. ps. sorry for bad English grammar, am improving each day, i hope so.
