Hi, past few days I've been having some weird pc crashes. It started when i plugged in my new monitor, but that doesn't seem to be the problem as I've plugged in my old one and the same crashes happen. I formatted my hdd because I thought some program was interfering, but the crashes still continued on a fresh w7. The crashes got less after I've installed the Nvidia beta drivers. They're pretty random, sometimes I can play games with no problems and sometimes there are periods where my pc will freeze when I open google chrome. It just freezes like if there was a blue screen, but there isn't one. The sound (if any) loops and nothing can be done except to do a hard reboot. My cpu and gpu temps are both under 30 when idle, so it can't be an overheating issue. Anyone knows how to fix this, or which component might cause this?
