Hey guys,


So, I have a six year old laptop that I use for on-the-go computing.  It is an ASUS N80v series, and it's a decent computer for it's age.


The only big issue I have been dealing with (for the past 1.5 years now) is the random crashes/freezes that occur suddenly, seemingly no matter what I am doing on the computer!


In July of last year, I created a post about this, and a very helpful BleepingComputer user HamLuis walked me through the process of checking my hard drive for bad sectors.  He helped me out greatly.  I ran 'SeaTools', the tool for checking for issues in Seagate HDDs, and my hard drive failed the test.  I subsequently created a bootdisk (as directed by SeaTools) for SeaTools for DOS for sector blocking, and they seem to have been successful in ignoring the broken sectors.


So today, a year later, I ran SeaTools again.  My drive has passed the test, so I do not know why I continue to crash daily.


When I say crash, I do not mean a blue screen crash.  When I "crash", my screen freezes like I paused a movie.  Also, it "freezes" the sound as well, so any sound that was coming out of the speaks during the freeze repeatedly skips as if to make a continuous buzzing sound.  There is no way around the crash but to cut the power and reboot.


Could this be a CPU issue?  I do not know much about internal components, but couldn't a CPU failure lead to a sound failure and sudden screen freezing, or would a CPU failure look different?


What further tests can I run on either the HDD or the CPU to check for these issues, or possibly resolve them?



Thank you for reading this!


(Extra:  Here is my thread from 2013 where Hamluis walked me through his steps to check my HDD.  My HDD now passes because of these steps, but the random freezing persists. http://www.bleepingcomputer.com/forums/t/502649/laptop-crashingfreezing-daily-more-info-in-post/)

I've had the same sorts of problems over the years and it was never the CPU.


These guys will tell you the technical things to do, but, basically I guess you would want to test your ram, update your video driver (or freshly install the same one if you already have the newest one), possibly monitor your temperatures.
