I got my Alienware m15 R7 about two months ago. It has this problem during low demand applications. I use this computer for school and when I’m scrolling on the web it will randomly just become unresponsive. Sometimes the window will load and become responsive but will freeze up often. Restarting my computer helps. I’ve ran system checks, gone into Alienware Control Center to run system checks and all come back clean, drivers are all up to date. I’ve restored the drive and it says there are no problems. I’ve tried changing browsers and the problem persists. I have yet to do a clean install of windows. Should I try that or is there something else I should do?
