Low fps in games after getting out of sleep mode

I can get something like 110 FPS in Dota 2 but after sleep mode it will fluctuate from 10 to 30, 40 if I'm lucky, FPS. This happens on Windows 7 as well, I have to constantly reboot my PC and obviously I'd rather not do that, since it's bad for my hard drive.

This is my GPU usage while this problem occurs: http://puu.sh/acoUB/fcd0a13ae1.png

Overclocking does not help.

Seems like a lot of work just to post a screenshot. Is it a rule here to upload screenshots?

Also, interesting.. video.
