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

stability lasted like what? 3 days?

Operating System: Windows 7 Ultimate 64-bit (6.1, Build 7600)

System Manufacturer: Gigabyte Technology Co., Ltd.

       System Model: EP45-DS3R

               BIOS: Award Modular BIOS v6.00PG

          Processor: Intel(R) Core(TM)2 Duo CPU     E8400 @ 3.00GHz (2 CPUs), ~3.0GHz

video card: ATI Radeon HD 3800 Series

Memory: 4096MB RAM

apparently i managed to trace the problem to the video card driver, but it is up-to-date. uninstalling-reinstalling it did not do the trick.

any suggestions?

McAfee was the problem for me. After days of headache with this issue I finally have it solved. My PC came with McAfee pre-installed from Dell and it used to freeze briefly, but would continue. But over the past couple of days it was hanging completely and I had to be constantly doing hard reboots.

When I first started researching this problem, I was convinced it was my ATI Radeon HD 3450 card and the driver problems that some users were having with this card. I even bought a new, updated video card, but still the same thing. Random freezing and constant hard reboots. I uninstalled McAfee and since then, not one freeze and the PC is noticeably quicker.

I now use avast! antivirus. I hope this helps someone because this issue was driving me nuts!!

NO, there is no single solution in all the posts.

Memory seems to be a common mention, as are drivers (especially video/audio), some people got cured by ditching a specific cordless mouse, some a specific MS update.

It has been a month since I have had any problem; last things I did, unchecked system set virtual memory, and updated (MS recommended) Realtek audio driver.

There is a fairly recent post on how to verify drivers. Also, lots of people seem to have ASUS MB, but mine is ACPI.

Welcome to the club, good luck. Check your memory with a thorough hardware checker, disconnect all peripherals that are not in use, and reconnect one at a time when needed seem to be good starting points.
