It works! I just did it with my olg 8800 gtx AND gts both now work.
The plastic parts have gone a little cream/yellow color and strangely, the stickers are still white, all but 1 anyhow, that one burnt into a brown crisp. The dvi ports are now yellow/brown and the fan power plastic thino is yellow now. ANYHOW it works! and I've tried it with WIC for 8 hours max settings and no crash. Today I've been playing Left for dead 2 and no problems! 1 week and its still going
BEST FIX EVER! THANKS!
