Does anyone know of a trustworthy program that can test my memory from inside windows? I know that the most popular one memtest86 requires running from boot, but the problem is my motherboard doesn't support booting from USB (as far as I know anyway), and I don't have any blank media to burn a memtest onto. So what I would like is a memtester usable inside of windows vista that I can scan my memory with and hopefully find a cause for the BSoD I've had.
