Windows 7: freezing up after sleep mode

Windows Server 2008 R2

Can you upload the .etl file the trace created (compressed in a .zip or .rar first, of course) to a file sharing site?

Do you have Intel(R) 82567LM-3 Gigabit Network Connection on your computer? If so, that's the reason why it is freezing up your system.

Well, I did see the total stoppage of just about everything in your trace all at the same time, and the odd thing is, a driver loads just as everything is stopping - avast (aswsnx.sys). The fact that, right as everything is freezing, the avast driver loads.... frankly, that's very, very suspicious. What is happening is that once the system is up, it looks like explorer.exe is parsing your E: drive, specifically the Music folder - this consumes almost 100% of the disk's time, which is fine - CPU usage is normal, etc. However, *as soon as the avast driver loads*, the entire system comes to a halt, CPU time drops to 0% used, 99% idle, and the disks go virtually silent.

Honestly, if this were my machine, I'd be uninstalling Avast (and making sure the drivers are actually gone after the reboot), and I'd try again to see if the problem continued. This could be a red herring, but it doesn't look like one. Here's the relevant data - the top portion of the graph shows disk activity, and the bottom shows driver load and delay - note that you can see ntfs and filter manager (ntfs.sys and fltmgr.sys, respectively) get called multiple times in sequence, which means a driver is loading (and the disk is being hit to load it) - what comes after is the avast driver, which is the *very* last activity in the trace you took. Again, it *could* be a red herring, but it's not likely.

Thanks for your help. Since Avast is otherwise a good program I'll try disabling the automated scans that the program has been performing at boot time and system start-up first. If the problem persists, I'll do as suggest, and uninstall the program, drivers and all.

Thanks again.
