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

This is an update to my post on Saturday, January 30, 2010. Unfortunately my proposed "fix" didn't last much more than a week.

The computer froze this morning shortly after using Skype.

There were a bunch of System log messages (Information 2/1/2010 7:57:50 AM Service Control Manager 7036 None) about various programs entering the running/stopped state before it froze.

I am having a freeze problem . i have win7 prof installed on a brand new pc .

gigabyte p55

core i5 2.67

ati radeon 5700 series 1 gb

2 western digital hard disks , one is external

asus wireless

500w coolermaster

the screen goes black , at random times . when i first met this problem , i thought its the battery settings . so i changed to off the hybrid sleep, turn off hard disk after not in use for 20 minutes , and turn off display , i turned those options off .

in addition i turned off hibernate from cmd prompt . i did not have the freeze problem for about 10 days and i thought it was fixed . but few days ago appeared again .

i changed my theme , some ppl say AERO theme its the problem . some other say reduce the cpu from 4 cores to 1 , this is not gonna happend tho , what the meaning of having i5 then ?

i stressed up my i5 cores , and graphic card with ati tool , i also played state of the art games with the best quality and not a problem ,

just random freeze . i noticed that froze 2-3 times whlie watching videos .. ive got tho the latest drivers .

only solution is to try reduce my ram timings . Anyone tried it ? dont wanna harm my pc ...

im considering install XP instead of win 7 . untill a SP1 come out .

I am having the same issue with my new Dell XPS 435T running 64 bit Win 7 - Core i7 - 920 with 12 GB Ram. Computer shuts down randomly approximately 2 week intervals. I have already spent 3 hours on the phone with Dell.

Ran self test on APC Power backup and the new Dell computer abruptly shut down, yet when I used the APC on my XP computer I had no issue. I had no power outages in the past couple months, but the backup does kick in for brownouts. Could there be a compatibility issue with the backup and the new computer's power supply / power management?

I'm glad I found this thread, because I'm having similar problems with my PC. I feel that my problem is sound-related though. I've currently switched back to XP x64 because I never had problems with lock-ups until I switched to Win 7 64-bit. My PC is running fine now. It's pretty frustrating to go through all kinds of tests only to switch back to an older OS as a final solution. I hope Microsoft is watching these forums so that they can find a solution.

The problem's not limited to ASUS boards, by the way:

OS Name    Microsoft(R) Windows(R) XP Professional x64 Edition

Version    5.2.3790 Service Pack 2 Build 3790

Other OS Description     Not Available

OS Manufacturer    Microsoft Corporation

System Name    KING

System Manufacturer    Gigabyte Technology Co., Ltd.System Model    G31M-S2L

System Type    x64-based PC

Processor    EM64T Family 6 Model 15 Stepping 6 GenuineIntel ~2400 Mhz

Processor    EM64T Family 6 Model 15 Stepping 6 GenuineIntel ~2400 Mhz

BIOS Version/Date    Award Software International, Inc. F10f, 6/1/2009

SMBIOS Version    2.4

keep an eye on the audiodg.exe task process. It has been known to exceed 1GB of commit memory use and I use 2 memory task utilities to keep this task process within its normal tolerances of 40-140mb use. If it exceeds this, its leaking memory. I use memclean and Minimem utils to control its memory use and reallocate its memory hogging. Until Microsoft fixes this ____. Audiodg.exe has had a problem based on many forums posts from the early Vista days. Its a go-between file between teh OS sound system and your sound card drivers to prevent your system fromo crashing in the event of a sound card driver failure.

I did some digging on audiodg.exe, and this could be the likely problem. It doesn't look like I can just disable the file either. I'm a bit tired of reinstalling OS's right now, so I think I'll stick with XP for the time being. Thanks for the help.
