I m using Acer Aspire 6920-6875 laptop. I have started getting one problem for last 2 months. At first, it was getting frozen and then i always had to turn off the system by using the power button.Then after few days, the system started shutting down suddenly. After using 'Advanced system care' program, now my screen doesn't freeze that much but system still shut down abruptly. Interesting thing is that sometimes it runs without any problem for 7-8 hours BUT other times, it shuts down suddenly within 2 minutes,sometimes even at startup. I m using various Anti-Virus,Anti-Malware,Anti-sypware programs and there is no prob related to this. Also i use a program to check my CPU,HDD temperature and its normal.
I will appreciate any help since i m very tensed.
