So a week ago i started getting crashes and blue screens. After loads and loads of reading, installing drivers and updating bios i ran a memtest86 and apparantly one of the two 4GB Corsair Vengeance CML8GX3M2A1600C9 has errors, and the other doesn't. Changed slots, one worked on all 4, one gave errors on all 4.

All the hardware is about 1 month old and i was wondering why after 3 weeks a memory module suddenly goes bad.
More importantly, what could i have done to cause it? (drivers? hardware conflict? i have no idea)
When i get a new one through RMA i'd like it to last longer then 3 weeks :S.
