My HP pavilion HPE (beats audio) $900 computer, for the second time in less than a month, froze up, upon booting up. Just stays on windows logo. so had to do a hard shut down, then re start. (and all was okay) any suggestions. This computer has been returned 4 times in the past year, for problems, I/e bad fan, defective hard drive, won't connect to wifi, etc. what a piece of junk !!
