New build occasional Bluescreens

Thanks, I downloaded it and ran it. Seems to point to either a driver or RAM issue. RAM is my biggest suspicion at the moment due to how much less frequently the crashes happen with Expo disabled.

Run memtest through the Computer. When it runs, if it's a faulty RAM stick it often will turn red quickly, otherwise wise leave it running (usually can take several hours or even over night).

good idea 

just to add, test them one stick at a time, remove the others, often times you find a bad stick when it won't boot up at all
