BOOTMGR missing or corrupter...but not all the time...
Desktop won't boot all the time. It seems like it only has the problem in the hot afternoon or evenings. Sometimes it boots fine and he can use it. Sometimes it freezes in Windows. Other times it won't boot and says BOOTMGR missing or corrupted. (mcp6p m2+ BIOSTAR) BIOS CPU temp averages between 92 and 100 degrees F.
