I have the Alienware m14x R2 for about 2 months and have noticed severe performance drops playing various games such as WoW, BF3 and CS:GO. Upon various troubleshooting methods, including the on suite dell doctor, I have installed CPUID software to monitor my CPU and GPU temperatures.

I have a Dell Inspiron and have had it for a year. Over the past week, when I have been using the computer it stops responding and I am unable to do Ctrl Alt Del or do anything except a hard shut down. This has been happening at least 5 times a day. It is also not shutting down now.

We have a stack with (2) 6224s. On port 2/g24 we have a 1000-LX SFP. It seems with that installed and operating ALL the other copper ports (1/g21-1/g24 and 1/g21-1/g23) no longer work. I can get link lights, but VLAN assignments appear to be ignored etc and no traffic is passing on the copper ports.
