I have seen something like this before a friend of mine bought a new computer when we were in college and it kept having issues. One day in class we figured it it had a BIOS virus right from the factory. Easy enough to fix just flash the BIOS and everything is back to normal or pull the bios battery out over night. This is not the first time something like this has happened from computer manufactures. This is how ever the first time I have ever heard of server hardware having this issue.
