Hi. So today my computers being a bit wierd, in windows it keeps showing little yellow or blue dots which i guess are artifacts. I have overclocked my 4830 before but nothing that drastic, and I've put it back to stock now. My CPU is overclocked but I imagine the problem here is with the graphics card. Games seem to run fine (cod4, l4d etc) with no noticeable artifacts. I don't think my temps are too high, the card usually runs about 50c idle and peaks at 65-70c after heavy usage. I'm also using the latest drivers (9.6). So basically I just wondered if anyone has experienced this before and knows what to do, thanks. Here's the pics: And here's what those pictures look like when I previewd this post: Recursive distortion for the lose Thanks.
