Random freezes with windows 7 - 64 bit

I have been experiencing the random lockups with the power button hold for 5 seconds as the only alternative also.  I am running AVG 9 just like you.  I will be removing it this evening.

Dell Studio XPS

Win 7 X64

Look guys and girls, i have read all your complaints about Windows 7. Yes, you asked for it, Microsoft did not. Windows Vista is a beautiful operating system once you master the navigation game, it is very roubust, security intense and does'nt have as many problems as Windows 7. It's incredible that so many people would jump so fast from Windows Vista which has a lot of practical features to one that is basically the same but with a lot of bugs. Microsoft is going to have some home runs but they are bound to have some strike outs! This is one of those strike outs right now until Microsoft can download updates that will resolve many of the problems that users are experiencing right now. The golden rule is never purchase and install the beta version of any operating system until the general public and PC magazine editors are satisfied with the initial version. This may

take six months to a year.

Unfortunately,your only resolve for this problem is to first uninstall Windows 7, reformat the drive and reinstall Windows 7. After reinstallation you still have problems with freezing applications, Click Start, in the RUN box type msconfig.exe. This dialog box will allow you to disable applications that automatically loaded into memory after Windows GUI is loaded into main memory and appears as your desktop. There will be several tabs to choose from, select the one that says startup and click the check box beside all the programs except those that say " SYSTRAY or Expolrer.exe", and click ok. A dialog box will appear and ask you to restart now or later, click restart now.

After the system restarts and your at your desktop, run one application at a time for 20 to 30 minutes. When and if you experience a freeze in a particular application, make a note of that application, close it using task manager. Use this process for every application until the last one in your program folder has been launched. Uninstall those that freeze up. If this resolves your problem then the problem is a compatiblity/ driver problem with those problem applications also use the program compatibility utility. If neither of these solve your problem then uninstall 7 and roll back to Vista, home sweet home!

we dont jump to windows 7 coz we dont like vista . we install win 7 coz we want to test them and we want to be up to date . win XP are perfect , does this mean that i was when i install vista over xp ? no coz i used xp for 2 years and its time to use vista . same with win 7 . Also , with this kind of problem we learn more about computers . in general .

OK, so I decided to take another crack at the freezing issue, and here's what I found so far.

I've been monitoring the audiodg.exe process, and the commit memory has been holding steady at 30MB.  What I did notice though, was that one of the svchost.exe processes has been slowly eating up memory.  The name of the process is svchost.exe(LocalSystemNetworkRestricted).  I tried shutting it down a moment ago, but it restored itself after a while, and during that time, my PC locked up.  The interesting thing is that after about 3 minutes, my PC went back to normal without any intervention from me.

So it appears that my random lock ups are temporary, but they're still annoying, and this particular svchost is my current suspect.
