Lag and freeze up problem w/ Windows 7

I am running Win 7 (X64), been using Firefox (32) without issue and yes, I have to run IE8 (32) or the (64) crashes, highly unstable.

If you are getting corrupt downloads, "Fire fox" and browser crashes, I would make sure your nic is working. One major problem my son had was finding a nic to work well with Win 7 X64, we went through a few and finally managed a Dlink to work properly, others would not work, or crash the browser and give him 28k speeds on 2mb internet.
