People of the internet!!!!

Please help me. I overclocked my GPU on bootcamp (Win 7) with MSI Afterburner. It works well and gaming performance is great but sometimes when I reset the clock speeds to stock speeds, the clock speeds randomly spike (usually when using a web browser) and this causes flickering on my screen.

I managed to fix it once by deleting and re-installing the display drivers, but this is a ball ache as I'm not using the standard Apple driver. I don't think I've fried my GPU because everything is A-OK on my Mac partition. I think its something to do with how the clock speeds alter depending on GPU usage and it can't work out properly what speeds it should be at. I think this because when I fix the clock speeds, at my gaming speed for example, the problem goes away.

Here are my specs and the speeds I'm overclocking to:

15inch Macbook Pro (2011)
Mac OS 10.9
Win 7 bootcamp
Intel i7 2.2GHz Quad Core
8GB RAM
ATI Radeon 6750m
1GB VRAM
Catalyst Driver - 13.4

GPU Overclocking speeds:
Core Clock - 780MHz
Memory Clock - 900MHz

Please help, I'm worried this random spiking might damage my GPU.
