Thanks, nikorr, I'll try the photo thing again.
I ran Windows Memory Diagnostics and it never came up with any errors. It also didn't show any results after the computer restarted though either.. But right up to the end of the test it didn't show any errors.
I might just contact G.Skill anyway and see what they say.
If it was me, I'd exchange it, just in case....
For the picture, quick check if all is OK, is the BBCode next to the report button.
