Upon arrival and turning PC on, the start-up was slow and it sounded like mini ball-bearings were rattling around inside the computer. Upon using the desktop different applications including the internet browser ran slow and/or locked up. Attempting to access the Task Manager completely locked/froze the computer out for over 30 minutes. I disconnected the power and reconnected after several minutes. Computer ran fine, and then the entire process repeated itself. Computer operates mostly ok for web browsing and text documents, but the computer often freezes momentarily. Off and on it still sounds like mini ball-bearings are rattling around inside. I will be returning my computer and expecting a FULL refund for a faulty computer that I sought out for the reviews and capabilities that it possessed...Once again, I will be without a computer until this gets resolved.*Update* Received an email from the seller today, requesting that I take this feedback down as it makes the seller look bad. Extremely disappointed in the clientele that Amazon now exhibits.
