Random freezes with windows 7 - 64 bit

Anonymous

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

    Problem solved :: just increased the ddr3 ram voltage to 1.6v from bios, not else no tweaks with the clocks or any other thing. This will work please reply if this works.

    I am facing the same problem of random freeze on my new pc (jus 2months old installed with Win7 x64 ultimate )

    While watchin a movie it hangs up with a sound hum and i need to restart it

    Sometimes while playing games too it hangs up, sometimes BlueScreen, sometimes totally hangs but hdd led blink ,,  but in all the cases i need to force restart the system.

    So i even tried to change the ram timing from my bios as specified by my motherboard specs on intels website but still the problem is not solved.

    All the drivers / bios are updated.

    Really this problem has now emerged into a super waste of time and money....i would like someone from the community to solve this problem . Please Help..

    the first post on this thread is in Oct 2009 now its 2011 but still no perfect solution to this problem.

    Is it hardware related or software related ? some says that MS gonna fix the deadlock problem with lass.exe but seriously this problem of random freezes is a havoc like thing...:( :(

    Specs :

    Windows 7 64bit ultimate

    4GB DDR3 Kingston ram

    Intel Core i5 760

    Intel DP55WB motherboard

    9800GT 1GB GPU

    1TB HDD Hitachi

    @Rachit2588, did you already check your drivers with Verifier.exe?

    Which Anti-Virus are you using? Did you try other Anti-Virus in the past?
