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,

My random freezes was triggered by a 100% HDD activity time without any or low I/O value. My first thought was a defect HDD so i checked these case without any result. The EventLog shows me many advices with the EventID 7036 (divers messages, "Dienst "Diagnosesystemhost" befindet sich jetzt im Status "Beendet"". is a message frequently seen).

in my case the only working "solution" (It is not exactly brilliant) is to disable the "Diagnosesystemhost" and "Diagnosediensthost" (sorry i dont now the service-name on english systems). I tried many other things like various driver for various components, disabling several tasks (Prefetch, SearchIndexer, and so on), clean system install (incl. required applications), changing RAM / CPU / BIOSsettings, changing system settings (Temp-location, swap-file size, ..), sequential installing win updates but nothing helps except disabling services named above.

Up to now i cant discover the real catalyst :/ Indepentend from these freezes i ordered a SSD now, but possibly it solves the problem because from time to time i read about problems with WD Green HDDs on Win7 (?).

I think it is a Win7 / Win7 Driver problem, because before i installed Win7, my system runs very fine on Vista Ultimate (proper system specs (software and hardware))

System: WIN764Bit Ultimate, I7 920 (OC / without OC), Corsair HX3X12G1600C9 XMS3 (12GB), Asus P6T WS Pro (Bios 0804), Western Digital WD10EADS, Asus GTX 275

Edit: I laughed to soon, after few hours without problems, win7 freezing again (but in a lower frequenzy). It's very annoying, it's not possible to work with this machine and the point to drop the complete pc out of the window come closer and closer.

BTW: Sorry for my bad english, it's a "little" bit rusty :)

I've been doing a fair bit of research into this matter and it appears that AVG 9 seems to be a significant trend to this problem .

Out of interest, how many of you guys that are experiencing this problem are running AVG?

I was. I have removed it and replaced with Microsoft Security Essentials . Since this I have had no problems. (Fingers crossed).

Good luck!

I'm using AVG 9 as well. I was using Microsoft Security Essentials a few weeks back until the system crashed and I had to do a clean install. I'll stick with AVG until someone finds a resolution. I don't want to go through the hassle of a reinstall just now.

Your English is perfectly understandable and very easy to follow, you should see my German, you would laugh hysterically at how pathetic it is =/

If what you are saying is true, I can also tell that disk activity may also be at a root cause because the way the audiodg.exe file interacts (and degrades) with the system performance due to the way the 11ms timing of the audiodg.exe file cleanup works in relation to the disk activity.

I have noticed some very weird activity in the way Win7 acts when its required to interact with a piece of software (audiodg.exe is the Win7 interface with the sound drivers of the computer) that requires the harddrive to act on it like fast small deletions of temp data and extremely fast interactions of small stored data like fast sequential writes. I am not sure where this bottleneck may be occurring but I do believe that an SSD may be the only true way in the future to overcome the now antiquated hard drive system we still all use in today's computers.

Can today's computers be getting so fast that the physical data that is stored in them is creating a huge bottleneck because of antiquated Hard Disk technology?

First i would like to say thanks :)

last night i tried to complete disable my sound device (deinstalling drivers and disabling hardware) but i doesn't solve the problem, hdd activity still goes up to 100% in random intervals and durations (in other words win7 still freezing like a charm). Anyway. Tonight i also stumbled across a new nvidia driver version (196.21 WHQL, released on 2010/01/19), since i have installed this driver, my system runs nearly 12 hours without any freeze (All System-Services and Tasks enabled). I hope this is a permanent status.

Yes i think so, i think classical mechanical drives (SATA / SAS ...) will first degraged to mass-storage devices in areas without any requests on performance and then they disappear sooner or later completly. IMO they allready have only the advantage of price per Mb but wait 2 or 3 years.
