I have an ASUS ROG laptop, its older, but I love it. I try and use it to play games and I've noted that after 2 or more hours it crashes; the screen goes black and the system basically hangs. I have to do a reboot to get it up again and usually I don't use it again until the next day. I suspect it is overheating. Are there any utilities I can use to watch the temp on the system as I use it? Also, is there anything I could do at all to remedy this (outside of buying a new machine)? Also It gets really hot on the bottom as I use it.
