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,

Found these articles:

http://arstechnica.com/microsoft/news/2010/02/microsoft-details-windows-7-memory-leaks-hangs-freezes.ars

and

http://www.zdnet.com/blog/datacenter/random-freeze-problem-chills-windows-server-2008-r2-windows-7/411?tag=nl.e589

Microsoft describes the symptoms as:

A computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly. Applications or services that are running on the computer stop working correctly. Additionally, you cannot log on to the computer by using the remote desktop connection utility.

And the cause as:

This issue occurs because of a deadlock condition between the Lsass.exe process, the Redirected Drive Buffering Subsystem (Rdbss.sys) driver, and the Winsock kernel.

The hotfix is part of what will eventually (early 2011) be released as SP1 for Windows 7 and Windows Server 2008 R2.

http://support.microsoft.com/kb/2265716 Has anyone has any luck with this hotfix or related issues. It sounded like the exact problem I've been having for the past few weeks. My machine will randomly stop responding for anything from 30 seconds to 5 minutes then come back like nothing was wrong. I tried the hotfix, it made it way worse. Luckily it uninstalled ok.

WOW!!! It looks like a lot of people have this problem. I've searched everywhere on the web for a solution. I haven't come up with anything that works.

Why isn't Microsoft proactive in dealing with this issue? The attitude seems to be--just ignore it.

Well it would seem I am now also a member of the what the heck is going on with my computer club.

It all started happening to me yesterday. My monitor stopped receiving input from my machine and my machine was "stuck", I guess, I couldn't turn it off normally. It still appeared to be running, the power light was on and there were the normal fan sounds etc., but the only way I could get it to power down was to unplug it. When I plugged it back in it automatically booted back up and I have been going through this process over and over as I try to solve the problem ever since. Oh and I should also add that since this started I have also been hearing occasional pops/clicks/static from my speakers.

I have read through this forum and tried numerous fixes and have yet to solve the problem. Sometimes everything is fine for an hour sometimes mere minutes.

All of my drivers are up to date. When I run Core Temp my temperatures are okay. I've custom set my Virtual Memory to 4000. Turned off all of my StartUp programs.I have added {C:\Program Files\Microsoft Security Essentials} to my list of excluded files to scan in Microsoft security essentials and still the problem persists. Even in Safe Mode sitting idle.

I have yet to roll it all back to factory, but that seems like my next step (although it doesn't seem to be the absolute solution from what I've read).

I am running Windows 7 x64 / On a Gateway DX4300 / with a Gateway RS780 Motherboard / AMD Phenom II x4 810 Processor (4 CPUs), ~2.6GHz / 6144MB RAM / ATI Radeon HD 3200 Graphics card.

This machine is fairly new and I have been running it problem free since I've gotten it until now. Any Suggestions will be greatly appreciated in resolving this matter. It has me thoroughly frustrated.
