start -up & shutting down freezing
i have problem on my laptop during start-up process & shutting down because most of the time its suddendly unresponsive,totally freezing & the only way to get back to its normal state is when rebooting it by hard reset.
i have Acer aspire 5750 12.04 (Precise Pangolin) 64bit, 4 Gb ram, Intel HD graphics 3000. I had noticed after updating my system on
available updates the following day the said error will occur., please guide me what appropriate updates
should be done only in order to avoid the problem.
