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

    As an update to my last post on the subject of lockups freezes and shutdown hangs, would anyone reading these posts having similar problems, be able to tell me if they are also having increased seek times with their (CD/DVD Drives)

    My Drive now takes 3 to 4 minutes to respond when I insert a disc this has increased my frustration factor now to ballistic levels.

    Not Bloody happy MS.

    Also does anyone use NERO 9 reloaded pack Burning software with Backup&Burn, as I have noticed some strange results with regard to lockups and Drive seek times. My Optical drive is fairly new drive (Liteon Sata DVD burner)which ran Just fine Before switching to Windows7 Pro64

    I should also point out that like many people I am just average computer user, I spent my hard earned money upgrading my system with components that would deliver a stable PC environment, so that I could enjoy running some of the latest games and other software smoothly and trouble free, my skills and understanding are good at least good enough to know when something isn't working right, and possibly do what are the suggested fixits but, something is very wrong and I know it, others will too. So to microsoft I say DIG DEEP BOYS AND GIRLS, find a solution and do it soon send out an email develop an Service Pack admit that there are some design flaws and get on with it.

    Please

    Have to tried using the "High Performance" plan in the Power Options?  I've been stable (so far) after changing my plan from balanced to High Performance.  The theory here is that something in the power management in Win 7 is hosed, and the High Performance plan basically disables the OS power management features.  You might also try to disable any power management setting you can find in the BIOS.

    That really is annoying.

    We buy a system that supposed to serve, and become servants to the system trying to make it barely work!..

    that was quality words!

    Same here.

    My system (Dell Vostro 430):

    Win7 Pro 64bit

    CPU i7 860 Quad

    MOBO Intel/Dell D735T

    RAM 8Gb DDR3 1333MHz

    GRAPHICS AMD RV710

    Sound Onboard Realtek HD

    Regularly crashing/non-responding apps (mostly IE8 and MSN Messenger), BSOD few times, etc.

    Re-installed fresh three times, sometimes for a couple of days no other programs but Microsoft Live + Microsoft Updates + Adobe Flash, and system was still unstable.

    That really is annoying.
