I'm not exactly certain when I purchased my desktop and am looking for all the information on it as this is posted. About 2 months ago my desktop would beep an unlimited number of times upon booting up whether restart or shut down. I unplugged the power source and waited until the morning and plugged it in and it worked fine and just kept it on until updates and such. I recently went out of town for 8 days and had my computer turned off. When I got back home and turned it on it started updating windows and at about 60% of the updates it went to a black screen and began beeping nonstop and so I unplugged everything attached to it and let it set overnight like I normally do, but this time it didn't boot up it just keeps beeping.
