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

    Same issue, random freezes, Windows 7 64bit, 12 GB of RAM, Core i7 920, Asus P6T.

    I do not appear to be experiencing freezes with the same frequency as most.  My system will be stable for days at a time, and then I just move the mouse and everything hangs, locks up hard, no blue screen, it just freezes - requiring a hard reset.  It always hangs when I am basically doing nothing, and just as I've begun to move the mouse.  Odd.  Perhaps if I were a gamer I'd lock up more frequently.

    I've tried amping up the CPU/RAM voltage a little with no luck.  I don't have any overclock, and in fact I've tried underclocking. But basically I don't think this is a hardware problem as this computer was rock solid under Vista 64bit for several months.  This is very, very clearly a Windows 7 issue.

    Eagerly awaiting a fix.  This is a big black eye for Microsoft in my opinion.  I can no longer say that MS Operating systems are rock solid and stable - which has been my experience since NT 4.0.

    Thanks BlokeUK, I tried your suggestion with disabling the services but I do not have an Asus Control Service and the only item I have running after hiding all the MS services is XAudioService. After disabling that I froze again right away. After reading Dragon_Nexus post about virus I now recall switching from Avast to MSE and that's about when my troubles began. I am going to remove MSE and see what happens even though MSE is running on my desktop with an upgraded Windows 7 with no issues.

    Secondly, In the MS troubleshooting link you posted am I to start disabling the MS services that it first said to hide to see if any of those are causing the issue? I want to make sure I'm doing this right so I don't brick my machine.

    I have spent probably 40+ hours trying to get this to work. Probably better off just buying a new laptop.

    Thanks Microsoft for another wonderfully compatible product.

    It's not limited to Asus and Gigabyte. I have a brand new Dell XPS 16 with the same issue, and so does a colleague who bought the same machine. Dell has already replaced my motherboard - problem still exists.

    I repeat again it's not a hardware issue it's an MS issue

    clean boot does same thing

    xp works not 7

    If you want to run Windows 7 on your PC, here's what it takes:

    • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
    • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
    • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
    • DirectX 9 graphics device with WDDM 1.0 or higher driver '

    AM I MISSING SOMETHING

    i think NOT !

    WE NEED THAT FIX AND WE ARE NOT BUYING new PC it's new just like every ones here
