Hi. I don't have a clue. I'm sorry i can't help you. When our computer has one of those stupid problems we don't how they happened is difficult. But don't worry, I'm sure you'll be able to fix it. Or someone will fix it for you!
Great post and welcome:smileygrin:
This sort of problem suggests there is something terminally wrong with your HDD.
Back up any important data just in case.
