Windows 7 RC build random freezes on Dell E4300

[Consultant]

I installed MSDN RC build on my Dell laptop a week ago. Twice I've come out of sleep and the operating system freezes after about 30 seconds. No keys or mouse are responsive. I have to hard boot. I had this happen to me in Beta when I put the laptop to sleep and after awoke it running on battery followed by plugging in the power cord. That is not the case on RC. It's powered the entire time. I'm not running any of the Dell management software. I used all default drivers on the install.

Here are the laptop specs:

Dell Latitude e4300
4 GB ram
Core 2 Duo P9300 2.26ghz
Mobile Intel 45 Express Chipset
Intel WiFi Link 5300 AGN
Intel 82567LM Gigabit Network Card
32 bit Windows 7 RC (MSDN)

Software
Office 2007 Sp2
Avast A/V
Windows Live Mail
Seesmic
Office Communicator 2007

e4300 lock up on RTM

I now have the same problem on my Latitude e4300 on the RTM version even after clean install. I have all the latest drivers installed. I ran a thorough diagnostic scan with Dell support over the phone. They think it is corrupt software. Pretty generic. Could it be IE?
