I have been running into the same thing I thought My hard drive was going so I replaced it, but same issue it will goa a few days with no problems then I will have to reboot 3 or 4 time to get passed the blue sreen then I'm set for a few more days. my next thought is my motherboard is bad, but the hardware site mentioned in the Blue Screen seems bogus, so that leads so my next thought was is there some adware or virus that is capable of causing this problem? Any help would be nice.
