Hi. Just wanted to update on the GPU issue that was talked about here earlier. TeamWinminer support emailed me on the matter and said that it was actually just an outdated GPU driver issue. So if you're having the same problem, try updating your GPU drivers and clear benchmark in Winminer then try it out.
Kudos to them on getting to the root of the issue and helping me out.

Hope it works for the others as well.
