Attached CPU-Z Pics and Diagnostics. I've got a Alienware laptop that I mostly use for gaming. I haven't experienced any issues while gaming. However, I have a reoccurring issue when browsing the web. The mouse will lockup, then after 5-10 seconds, the computer will reboot itself. The fans don't rev up or anything before hand...there is no blue screen it just restarts after the mouse locks up. This happens in both IE9 and Chrome, though it seems to happen more with Chrome. I must emphasize "browsing." I can go to hulu.com and hbogo.com and watch TV/movies without it crashing. It's only when I'm browsing around sites like google search and youtube. I spent some time with Alienware tech support; they had me run a few hardware diagnostic stuff at startup that turned up no hardware-related issues. I've reinstalled both web browsers and this hasn't always happened. It's only been happening for the last month or so...the prior 5 months I was able to browse without incident.
