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

    I'm thinking of going back to Win 7 32-bit but then I can say goodbye to the extra RAM installed on my laptop. I never had a problem with windows until I updated to 64-bit.

    The random freezing happens when I'm watching anything dealing with flash or a DVD, and it sometimes happen when I am simply browsing the net and I am downloading something. I am confident that this problem is definitely software related.

    I have Win7 Utimate ASUS CG 5270, PQ5L mobo, Quad core 8300, with 8G ram connected to an LG 32" LCD.

    I found my lock-up was due to my Nvidia video card drivers.

    Originally it had Vista and a GeForce GT 220 video adapter and had this problem occasionally so I upgraded to Win7 and installed a GeForce GT 430 which worked for a while.

    Seems like the Windows Updates affected the operation also especially the ones over the past few months.. 

    I tried all the Nvidia drivers and some would work for an hour or so, some would not allow me to get to the Windows screen.

    260.55 seemed to work best but still occasionaly black screens.

    I went to safe mode to reset or restore the video using just the Win7 VGA driver which provided only 2 resolutions.

    Finally I removed the drivers, removed the video card and changed BIOS to use the integrated video.

    Unfortunately my score has dropped to 3.5 for business and gaming graphics performance (from 5.9) even with the latest drivers for my GTX 4500 integrated video adapter.

    So much for gaming but at least I have a useable pc again which will do BD movies and other non-intensive video functions.

    Hagd,

    Brad

    Im suffering with the same kinda of problem and im running Windows 7 x64, it used to be only with watching online videos and after say 30minutes or more but now it happens more often. Sometimes i can just goto the toliet come back and its frozen

    Ive tryed alot of the things mentioned in this topic (power settings/windows media metwork etc) and alass nothing worked. I tryed to install the hotfixes but it said "This update is not appicable to your system". So i couldnt even try them

    I was planning on taking my pc to a repair store but since seeing everyone with the same problem i dont want to pay money for something it does not need
