Random Crash from Sleep Win7 Ult x64

I put my Dell StudioXPS 1645 to sleep this morning and came home to find it failed to well sleep and BSOD.

Here are my specs and the dump.

I just recently had my bluray/dvd writer replaced.

welcome to SevenForums

Your BSOD was caused by

NETw5s64.sys which belongs you your WIFI card

Update your WiFi driver.

Can You run the SFD tool once more and click on the GRAB ALL button on the top and upload the rest of the files.

Why is your temperature so warm? Where do you place your laptop? Have you checked the case for any dust or lint?

The above drivers are all related to McAfee, as well as, mfeavfk01.sys and mfeapfk.sys, although no timestamp information could be obtained for these for some reason.

McAfee is a well known cause for BSODs for Windows 7, it's best to remove this program completely using the McAfee Removal Tool, and then install and run full scans with these free and proven alternatives which work with Windows 7.

Enable Windows Firewall (if disabled) with it's default settings -Install and perform full scans with:

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system

Well now that I know it was my wireless driver I know to be careful next time I sleep this thing. xD

Temps? This laptop used to run 20+ degrees hotter before I got the fan and heatsink replaced.
right now it is hovering around 50c. I must have taken the pic while I was running a defrag.

About Mcafee, I've had it for 3 years on this laptop and it has never caused a BSOD... yes a few hickups here and there but nothing their tech support wasn't able to fix.

Okay, 50*C is fine for a laptop.

I can only give you advice, so it's your decision if you remove McAfee or not.

Have you had any other problems? BSODs?
