hi to all,
I have a shutdown problem since one year ago when I changed my 32 bit windows seven to 64 bit. I need 64 bot windows to be able using all of my laptop ram capacity. but just when run academic softwares (MATLAB and HeuristicLab), and increasing RAM and Cpu usage to more than 90%, my laptop turns off without any warning but not immediately, it turns black for about one secound and then turns off.
I explained this with more details last year in this post. you can see results of some tests there.
it's not a thermal issue as explained in post above.
last year I reinstalled my 64 bit windows and the problem gone temporarily (I guess it was result of having much less programs an RAM usage) but after few days it occurred again.
last year I thought it was a HeuristicLab bug, but now it occurs again on MATLAB but I detect some new information about it.
First off all shut down occurs just when I am using parallel computing in both softwares (it never happens in daily works or on other softwares). my laptop cpu has two core and four threads, in MATLAB parallel have some controls, when I activate two workers and run the code, two of threads are idle in task manager and laptop never turns off even if I run the code for more than 50 hours; but when I use four workers, MATLAB uses all threads and more RAM and problem occurs again
I don't know this happens when I use more than 90% of RAM usage or CPU usage and why it happens.
I would be very thankful for any suggestions and help.
All drivers are up to date
