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 never had any problem with windows 7 64x in my Vaio Fw41E. Last week I made a format and reinstalled the same windows version, also 64 bit version, Professional Edition (MSDNAA) and now it freezes all the time! I am a computer technician myself and have tried every trick up my slieve and i haven't found the root of this! What I notice is that it freezes when the computer is stressed out, but my computer isn't exactly weak for windows, it scores 5.5, fairly reasonable score. I have MS Security Essentials, and SP1...I have all of my drivers up-to-date! I have no Ideia what so ever of what is causing this freezes!

MS, solve this!

Hi Guys,

There are couple of things that seemed to work for people here :
1. Changing anti-virus from AVG to MS Security Essentials.
2. Applying hot-fix http://support.microsoft.com/kb/2265716/en-us. FYI this is a part of later service pack 1.
3. Tune-Up to control the memory management.
4. BIOS settings change back to default in case you have fiddled with it.
Other than 4 have tried all the 3 and it is much better that the random freeze in every login is gone. The freeze still happens but may be once in 3-4 days which is still OK with me. Just to make sure my freeze is not BOSD but usually mouse and keyboard not responding which is fixed only after hard reset.

I am not sure whether I want to try to change my BIOS settings as it could be risky but will wait and watch this thread in case some BIOS expert can pin-point the actual issue.

Hi Arkinstrocity

Oh if only it were that simple. I have never use AVG, always used MS Security Essentials, and still get 2 or 3 freezes a day.

Still I hope it works for you.

ok. First of all I have had freezing problems for about 6 months. I have tried everython this thread.

About a week or two ago someone posted that they thought the problem was the free AVG anti-virus software. They uninstalled that and installed the free Microsoft Security Essential software and said it worked for them.

Last night i removed the AVG virus software and then installed Microsoft Security Essentials. To my amazement all freezing has now stopped. It stopped as soon as the software change and reboot had been done. Not a single freeze since.

I am totally amazed but extremely pleased to have my computer back.

If you're tearing your hair out and have AVG software then give it a go. If it works post back on here to let people know... we might have cracked it.

Good luck
