Random freezes with windows 7 - 64 bit

I use to run Vista home premium x86 on a acer computer. This summer I downloaded Windows 7 rc x86. A month ago I bought all new parts and since I could use 64-bit system now I installed a 64-bit Windows 7.  Then did the problem start. Every new and then the computer freezes, some days over 30 times. I thought it was hardware problem and tried a lot of hardware finders and nothing helped. I also installed windows 7 rc my mothers laptop (The same version I use to have that work fine) that used to run on Vista home basic.. But her computer didn’t freeze it just got a black screen now and then.

The I started to suspect that it was because it was a beta version so when windows 7 were released I bought two of them a 32-bit and a 64-bit. But the problem didn´t go away. It´s still there and It´s kind of frustrating and even more now when I’m trying to write a essay.

I used windows upgrade advisor and it didn´t see any problem with an upgrade to windows 7. What can I do?

Guys,

I might have the answer to your problems.  This might fix your sleep/suspend problems and your random freezing problems.  Bottom line is that the default and "auto" values in Win 7 and your BIOS might not produce a stable computer...even with a virgin install.

RANDOM FREEZES FIX:

My computer used to freeze randomly until I fixed the memory timings.  I suspected bad memory early on and tested it with MEMTEST, but it passed with flying colors.  I even tried swaping memory out, trying to eliminate bad memory and/or slots.  It turned out that it was a memory frequency/timings/voltage issue.  No more freezes!  If you have a similar setup, this will most likely fix it.  If not, then check your memory and/or power supply.

The "AUTO" settings in BIOS *may not* produce a stable setting.  You have to goto the ASUS support website and download the latest memory QVL and lookup the memory settings for your particular brand there.  For my memory (OCZX1333LV6GK(XMP)) I had to make the following adjustments in the BIOS:

DRAM Freq:1066  (even though my memory is rated at 1333 frequency, the QVL guide recommended a lower freq!)

7-7-7-16 for the rest of the timings.  The other settings I was able to leave in "AUTO"

DRAM BUS Voltage: 1.6

*warning: be sure to consult your memory/motherboard documentation...the wrong value could damage your components!

SUSPEND/SLEEP FIX:

My computer used to hang when coming out of sleep or wouldn't completely goto sleep.  This solution may be partially dependent on you fixing a random freezing issue if you have one. 

In your "advanced" power settings, disable "Hybrid Sleep".  That's it!  My motherboard doesn't like hybrid sleep.

*If you have a desktop with a UPS, Win 7 will treat it like a laptop and apply the battery settings....sooo make sure you adjust the "on battery" settings!

My setup:

Processor:Intel core i7 920

Motherboard:Asus P6T

Memory: OCZX1333LV6GK(XMP)    (ie. 6GB in 3 sticks)

Harddrive:  3 x WD Caviar Black drives in RAID 5

PSU: X3 1000W

Video card: 2 x NVIDIA 9800 GTX+ SLI

*I have all of the ASUS overclocking/energy savings programs uninstalled

*I have the latest BIOS 0801 and all the latest drivers installed

    There are three sets of audigy drivers to try:

    a) Generic (supplied with Windows 7).

    b) Download from Creatives site

    c) This one: http://forums.creative.com/t5/Sound-Blaster/SB-Audigy-Series-Support-Pack-3-5-10-11-2009/td-p/538381

    With all 3 sets of drivers I experience problems. I'm still thinking this is something to do with audiodg.exe (DRM) and possiblty driver interigration with this "wonderful" application I'd rather not run (and chews up my CPU time).

    NB Please let's not be too hard on people who are only trying to help here.

    allright,

     First let me apologize for being a little ____ last night to Mike from MS. Back is giving me ____,PC giving me ____,

    wife giving me ____...you know the drill.

     So last night I installed the drivers from the Mfg (SPARKLE inc) of my GPU. all went well. Installed Medal of honor,

    allied assault and maxed out the video settings. My Desktop is set to the max at 1280x1024.  The game played well

    for about 45min then locked up in the middle of some graphic intensive shooting with the sound just looping.

    I was able to get to the desk top via cntrl/alt/delete and shut down the game. My event log showed nothing and there were no spikes of the svchost.exe noted. This game does have a tendancy to do this on it's own so I'll assume this to be the problem.

     This morning, the PC locked up on bootup during the transition from the "slider" bar to the music logo pop-up wich is followed by the desk top appearance.  I had to do a hard reset and let the pc come up in normal mode and she did without delay.

     However, there was the HDD light, a solid blue again and the performance drop down for the HDD showed hundreds

    of my friend the svchost.exe. I highlighted some of the files and saw some of the music files in there as well as files from MOH allied assault! This CAN"T be normal for virtually ALL of my DLL files to go through this.

    What would cause this?????

    I'm going to try the clean boot fix that MS mike talked about while the PC is isolated from the net.

    Wish me luck

    PS- I just check the event log and all it showed was my usual 'EVENT 100' warning that boot up was slow.

    nothing in regards to the lock up first thing this morning.

    I could solve the problem on my Windows 7 by disabling the USB and PCI-Express power management features!

    My W7 is in French so I cannot explain you where these settings are, you have to dig deep in the power management settings ;)

    I also suggest you to start a memory test at startup, it didn't find any error on my computer. If it finds any on yours, you know what to do :)
