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

Hi all. Posted for a while and had problems after install over c drive (not the update install). I finally got tired of all the freezing, and completely wiped the drive, reformatted, and did a fresh install. This time, I did not install any of the Lenovo drivers and just let WIN7 do it's thing. It looks like I now have a stable system. The problem here (for me) may be the Lenovo WIN7 drivers just aren't working right. Letting WIN7 run the show seems to be working.

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

I too am expeirencing random Windows 7 freezes, but i have been having this issue from using Win 7 RC, the released 32 bit verion and today with the install of the 64 bit version i still have this issue which i will elaborate on.

First off my ssytem is a Dell XPS 420, which came with Vista 32 bit which runs no problems. I have been wanting to upgrade to Win 7 and as i previously explained i started off with the RC version. The issue i encounter is that after a length of time of around 1 - 2 hours uisng the computer in Windows 7, programs, folders, drives, explorer all stop responding. It generally starts with the window or application i am using which fades out and gives me "not responding." Then the issue seems to spread, i try the task manager, but i could never end a process, then that hangs, then all my windows hang, then my start menu bars freeze up, and then finally before i force a shut down, my background fades out.

At first it thought it had soemthing to do with the external hard drive, but after i disconnected it, used the system for 1 -2 hour, the issue repeated regardless.

I have downloaded all latest windows updates, latest chipset drivers and all other system drivers (not warning messages in device manager), it is a fresh install, but as i said i have installed Windows 7 different version from the release of Win 7 RC all the way up today, and the issue has not been resolved. I doubt it is a hardware issue, as my computer functions perfectly in Vista and XP. I have tried disabling sleep mode and hybrid sleep mode, through lookign through this post, but is anyone else experiencing the same freezing as i am?

Regards

Whisky
