All the drivers look excellent by eye. There's none I could even recommend to update.
Two things to suggest:
1) Run Driver Verifier in the hopes it will point to the problem in the next dump(s) you post. Here's how:
Link Removed
2) Use Memtest86+ to test the memory overnight. If you're also up to it, it could be run on one stick of RAM at a time, while all others are removed. This is the best way to single out any defective RAM modules.
I would also make sure that the bios is set manually for the RAM timings, frequency and voltage that the manufacturer's website shows. Use CPU-Z to get the exact memory module brand/model.
