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

    Well the solutions now have been discussed to death. If you haven't tried the hotfixes that I first came up with or disabling windows media network sharing by now then you haven't been paying enough attention or too lazy to read that which other people are spending time to write.

    Those with issues freezing with antivirus - ZoneAlarm has this issue, and the problem is keylogger software. ZoneAlarm comes with key logging protection, under certain conditions (not know yet) the machine will freeze or give a BSOD unless you disable forcefield browser detection/the keylogger option.

    So with other antivirus products, if you've got some options to prevent key logging, or some virtual stuff going on, you might want to disable this.... not sure of the detail but this may help as a clue.

    For me - I'm cured I think... although I'm still interested in installing that outstanding hotfix that still isn't available from MS yet.

    I wonder if the same can be said of Avira.....

    I decided to try Avira and MalwareBytes instead of Avast! and Spybot/Adaware that I'd been using before.

    Upon reinstalling I put m old programs back instead of Avira and Malwarebytes.

    You are right!  After removing AVG 9 my problem went away.  Of course that was only after I tried everything else I could think of including reinstalling Win 7 which resulted in the loss of some files that I wish I had back.  I wish I'd seen this forum before I reinstalled!  The reinstall also got rid of my system restore files so I'm stuck.

    In any event, things are working just find now.

    To all who may be reading this, if you're using AVG 9, GET RID OF IT--NOW and your problems will go away, at least mine did.
