Hello guys, I'm new to the forum and am not completely versed in computers. Please excuse my lack of knowledge I'm just a confused person trying to get some help. The last two days, my computer has been acting really weird. Two days ago it just slowed down. It took longer than usual to boot and opening any program took at least 5 minutes. For no reason at all, the performance completely diminished. Then yesterday it was unable to load boot properly. It kept telling me to select a proper boot device (I have not added any hard drives, in or out of the computer. This includes USB). Now it is finally working again and I want to post this in case something happens again. My computer is a Lenovo Idea Centre K330B. The processor is an i5 2310. I know it's not a lot of info but If you guys can tell me any other information you need, please tell me so I can add it here.
