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

I have identical problems to everyone else here by the look of things.

My freezes seem to be mainly when playing music, I have tried with WMP11 and KMPlayer and freeze freeze freeze :( I also get problems with IE8, Firfox 3.5, Opera 10, can't be sure about the browsers though, but can about music.

First I had major problems with my SApphire Radeon 5770 GFX and screen corruption I thought freezes were down to this but I guess not as an update to Catalyst 9.11 seems to fix the screen corruption but not the freezes :(

Has anybody managed to solve this problem yet?

My setup Intel i7 860 (not overclocked)

CoolerMaster Hiper 212 plus HS + Artic Silver thermal

Asus P7P55D motherboard

High Power 750W PSU

4GB Corsair XMS3 DDR3 1600 CL8 ram

Sapphire ATI Radeon 5770 1GB GDDR5 PCIE GFX

2 X WD Green 500GB Hd as Raid 0 Sata II

1 x WD 640GB Drive Sata II

2 X LG LiteScribe Sata DVD+-R/RW drives

Creative Audigy2 Platinum Sound (uses this for headphones and onboard for speakers)

Windows 7 64 bit

I have been following the steps in this article http://support.microsoft.com/default.aspx/kb/929135

I believe I have narrowed the problem to one of the following 5 services or startup items.

ATI Catalyst

HD Audio CPL

Intel Matrix storage drivers

Device VM Meta data export service

Asus control service

I can't figure out which one or combination of these causes freezes, what I can say is that with these disabled I have a stable system the longest so far by far and does not seem to cripple my system.

I am tempted to leave them disabled and worry about them if some need arises where I need one or some of them again.

My audio certainly is not affected, still playing HD and only one ATI driver recovered successfully warning.

The only odd thing I noticed was my bios and Task manager seem to think I only have 4087MB ram installed where I have 4096MB unless Ram manufacturers are using some odd calculation to calculate ram sizes these days as do hard disk manufacturers.

Interested to hear if anybody else has this ram discrepancy

******************************************************U P D A T E *************************************************************************

Well I believe I have fixed my problem.

Asus Control Service is definitely the problem, it is the only thing I do not have running now, and as soon as I started it problems began almost immediately, corrupt login screen, froze within minutes of logging in, either this is conflicting with something else (my suspicion is that it is fighting with windows control service).

I believe googling that the Gigabyte service suffers the same problem.

Perhaps this service just is not designed for Windows 7 (my guess)

Enjoyed hours of non freezing, playing HD Audio, movies and games without any glitch.

Out of curiosity I did enable the Asus Control Service one more time just to be certain, and exact same problem freezes, graphic driver crashing and corrupt screen, turn it off and problem goes away! surely this can't be a coincidence, so I decided to remove AIT catalyst from startup and leave Asus control service running, exact same problem, slightly worse by the fact I did not even get a login screen it was just white with a blinking cursor, disabled Asus control centre once again and et voila the problem vanished again.

I hope this helps someone else, I really do believe my problem is now solved, I am not entirely sure what the Asus Control service did, but computer runs fine without it, temps averaging 19 - 23C idle and 48 - 55C when being pushed with encoding or Prime 95.

I do still have the mysterious 4087MB instead of 4096MB ram issue, CPU-Z sees it as 4096MB Bios and Task Manager only see 4087MB a bios problem?
