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 have the same cpu/motherboard/memory setup, this worked to solve the hard freeze/hard boot issue.

    i'd be interested to know how many people in this thread are using a wireless setup with the Ralink RT61 chipset. i was experiencing the exact same issues as the rest of you until i updated to the driver that ONLY microsoft update catalog has - the 3.0.9.1 version of the x64 drivers for the RT61. nobody has mentioned wireless in this thread but that appears to have been my issue - Ralink's driver support is terrrrrrrible.

    I may be speaking too soon, but my computer has been "up" for over an hour now and that's a record since last Saturday night.

    My Blue Screen of Death occurred when playing Bejeweled Blitz on Facebook and when watching videos that used the Flash Player. (I have Windows 7 64-bit like many of you.)

    I played Blitz on Google Chrome, which has its own Flash player. I *think* that there is a conflict in having both the Chrome Flash Player and the Adobe Flash player downloaded from Adobe's site.

    I uninstalled Google Chrome, and I haven't crashed since.

    I had a few problems about 4 months ago that seemed to fix themselves when I downloaded the driver for my monitor rather than using the generic, but something happened on the weekend that sent everything into a downhill BSOD spiral.

    I'm crossing my fingers that this is a permanent fix. I feel all of your pain!

    Windows Hotfix KB2265716 ("A computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly"), released August 15, 2010, may be helpful to some.
