For a while I've had a problem with my computer freezing for about 4 minutes after I wake it from a power saving state. I can't remember what the power saving state is called but the fans switch off, the hard drives power down, the monitors go in to power save mode, and the only sign of the computer not being completely off is the power LED blinks. After I press a key on the keyboard to wake the computer the monitors come out of power save mode, I think there is a little bit of hard drive activitiy, but then the computer freezes like it is waiting for something. When it freezes sometimes the Windows password prompt is shown on the screen with a frozen mouse cursor, other times the screen is black with a mouse cursor that doesn't move, or the screen is just black with no mouse cursor. The keyboard is locked-up, too. Pressing Num Lock and Caps Lock doesn't register and looks like there is no hard drive activity. Then after about 2 or 3 minutes the monitor goes back in to power save mode. That may be the result of me setting the monitor to switch off after 1 min and setting the computer to sleep after 2 min so that I could quickly get some info from Event Viewer about this and test if any changes I made helped the computer wake from sleep. Eventually after about 4 min if I touch the keyboard or mouse again the monitors will power on and I can enter my user account's password and go back to the Windows desktop. Sometimes, but not always, when I arrive at the desktop I see an error message telling me Media Player Network Service didn't start.
Recently, I tried some things hoping they would fix my computer's problem. I reset the BIOS back to defaults. Or, at least used as many defaults as possible and still be able to boot in to Windows. I ran Microsoft's Fix It for power issues. It just complained about the hibernation file being too small and something about a setting for when running off a battery. Actually the hibernation file's size was 75% of total RAM which should be ok according to Microsoft. I set it to 100% just to go along with what the program recommended. This is a desktop computer. I let the program fix the battery power setting issue and then reran the program and it still found the same battery power setting issue. I don't know if that's a problem or not.
In Event Viewer I made a custom view showing Critical, Warning, and Error event levels from the time Windows booted until the computer went in to power save mode, and until the computer completely woke from power save, and I saved the events as an .evtx file. [attachment=141904:wakeupissue.zip] I think you can open it in Event Viewer on your computer and browse the events. However, there are some other errors and warnings in there that probably aren't related to the problem of my computer freezing durring wake up. The Media Player Network Service error isn't in the event log that I attached but it metions something about blackbox.dll.
Mainly, I'm interested in fixing the problem with the werid freeze after waking the computer. However, if you notice some other issue in the Event Viewer log that you can help me with then let me know. I plan to work on the other issues later. I'll provide more info about my computer's hardware if you want me to.
