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

Just had 'unofficial' word from Dell that prob is recognised and is related to 64 bit W7. Issues are related to Bluetooth and WWAN and possibly other I/O. Fix is in the pipeline.

This is not an authoritative answer, just a infomal tel conversation I had with a account manager at Dell.

The authoritative answer is that some issues are caused by USB (see hotfixes above) and a possible ASUS/USB compatibility problem.... so far nobody has tried them/given any feedback....

Well, I am not 100% sure that I have solved my problems yet, despite it seeming to run fine once I had disabled the 1TB drive.

I was watching a BBC iPlayer download of Strictly Come Dancing last night...my wife's doing...when we found the video to be a bit jerky. I decided to download the latest catalyst drivers from ATI, version 9.10 as I'd only been using the default Win7 drivers since I'd reinstalled.

The drivers installed without a hitch and it seemed to clear up the stuttering video. All was good.

I put the HTPC to sl;eep last night and came down this morning to resume it and install Live Essentials Messenger and Mail. Whilst this was happening, I loaded Media Centre and tried to watch a bit of BBC Breakfast. It seemed to freeze and not really let me watch anything - back to the old problems. I wondered if it was because I was installing in the background (even though this is quite a fast PC). Managed to get back to the desktop and shut down the machine. Restarted it and it was fine.

Had a think and wondered if it was when resuming from sleep mode that I have the problems. Tested it and it did seem to cause the same freezing problem. After a restart, it seemed to be fine.

Rolled back the graphics driver (embedded HD3200) and uninstalled all the ATI Catalyst stuff. Rebooted and tested. The freeze problem after sleep mode *seems* to have gone away. Further testing is obviously needed, but I found a link to suggest quite a few have this same problem and installing the Catalyst 9.8 drivers should fix it.

Here are the drivers:
