hi to all,
last week I change my windows. I reinstalled my 64 bit windows7 to be able use all of my ram capacity. (a 32 bit windows was installed before)
I use an academic software which use most of CPU capacity when run parallel computing.( HeuristicLab dev.heuristiclab.com/)
there wasn’t any problem in my previous windows except low ram capacity
since windows change, some time after runing HeuristicLab and reaching spu usage near 100%(about one hour but not always) my laptop turn off by itself!
It’s not an overheating or hardware issue for some reason:
1. It does not turn off suddenly and take 2-3 secs to turn off (like normal turn off but much faster)
2. When I turn on laptop again, there is not any start up repair or safe mode option on start up (this two happens for me when my laptop turns off from overheating)
3. My room is completely cool now, I use cool pad, fan speed is normal and laptop seems to be even cooler than usual.
I don’t have any antivirus yet, and installed my 32 bit drivers on new windows (no any error regarding compatibility issues)
it seems like a turn off command by windows or windows defender to me. Perhaps caused by high cpu usage.
do you have any idea or suggestion?
