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

    Maybe we should all put down our system specs to see if we can find a pattern in the hardware?

    You guys can use the following template to list your hardware. Just copy/paste and fill in or leave blank if you don't know.

    <p>My specs:</p>

    <ul>

    <li>CPU:

    <li>MEM:

    <li>MOBO:

    <li>GPU:

    <li>PSU:

    <ul>

    My specs:

    • CPU:
    • MEM:
    • MOBO:
    • GPU:
    • PSU:

    This also happens to me.

    • CPU: C2D E7400 2,8
    • MEM: 2 GB Kingston / 4 GB OCZ / 2 GB OCZ (tested all)
    • MOBO: Asus P5Q
    • GPU: Geforce 8800 GT 512mb
    • PSU: OCZ 700 W (i changed my old 500 W to fix this freezes, didnt help)

    Hello All, read through the whole list of posts and here is what I have.

    First off a desktop, custom built with my own hands

    <ul>

    <li>CPU:Intel(R) Core(TM) 2 Quad 2.4ghz Q6600 quad (overclocked at 3.37ghz) Win 7 64bit Ultimate

    <li>MEM: 6GB

    <li>MOBO: Foxconn(P35A)..I think, it's been that long since I looked

    <li>GPU: Nvidia 9800 GTX

    <li>PSU: Jeantech 600W

    <ul>

    This computer has been stable from day 1 at these settings both under XP pro and for the last

    8 months under Win 7 64bit Ultimate.

    Now the machine that has developed problems, and they do seem to coincide with one of two things. Either the latest fixes released or from the recent use of a wireless usb mouse, part of the microsoft 800 keyboard and mouse combi, which incidently works flawlessly on the desktop.

    Model Asus Aspire 7738G

    <ul>

    <li>CPU:T6600 Intel core 2 duo processor 

    <li>MEM: 4GB

    <li>MOBO:

    <li>GPU: Nvidia  GT240M

    <li>PSU:

    <ul>

    In the last 2 months or so since installing and re-installing Windows 7 64bit  (orginally suplied with vista) twice it has experienced freezes. No BSOD only freezes. I've followed all the advice here to date except the one about media sharing which I will try out. It has all the latest drivers and does not have any alterations to timings etc. bog standard. I've swapped in and out the memory modules, run memtest through 10 passes with no problems. It did seem to start with the use of the usb wireless mouse but I cannot remember at the time if that may have also been after updates had run. It does seem to me usb related though. I'm going to try a period of first of all, no usb mouse. Just the trackpad but I do notice this and the keyboard are registered as usb devices...Anyway after that I'll disable the media sharing programme and apply those later kb updates mentioned above. I'll let you know how it goes after a week. I should also add I've disabled all power settings as advised and run at max performance.

    Regards

    HA, well that rules out the actual wireless mouse which I didn't really think was the cause of the problem. Laptop has frozen up at 14:00. 1 hour ago. Hard reboot the only way out of it. I still think it could be usb related though as I mentioned before the keyboard and trackpad appears to be running of the usb bus. So it could be any activity on the usb bus. I don't think it's anything to do with drivers as my desktop is well stressed and overclocked both memory and cpu and it runs fine and I've had a variety of usb devices all connected at the same time to that. Other people here also have the same problem with different hardware setups as well.

    Next step I'll try the event logs and then disable that media sharing thingy.
