Some people had it happen when the computer was only days old. I went onto forums and saw this was amazingly common. There was an option to continue and doing, so, Windows would complete loading and ran normally.Īs it was running normally I continued in trying to get a smooth operation >Disk Clean removed 600MB of various files, I emptied the TEMP folder of 450MB, it hadn't been defraged since February 2012, and there were a number of superfluous programs.īut still, the 'Product information not valid'. I left, and when I restarted, before Windows 7 Pro started, there was a black screen 'Product Information not Valid' and that the computer didn't have the correct serial number, product number, and so on. I fussed with it a bit- deleting a few odd, unused programs, turned off and unpinned, descheduled, non-auto'd updated, and so on. Task Manager told an interesting story too- there were 135 Processes running and I saw CPU use at up to 90% and memory use up to 60% with the laptop sitting there idling! The Blue ball would just sit and spin for almost everything- and almost forever.
