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

what did you do to stop the freezing?

Advanced system settings, unchecked ...."system manage virtual memory", and set minimum at the recommended (3050), max about double.

Other changes also, so cannot be sure.

Remove your anti virus and go for Microsoft Security Essentials.

I was running windows vista 62bit on my hp computer. I installed the windows 7 and started having issues. I have read through the multiple threads. I have tried 2 things at one time so I can't be positive which one appears to have fixed my computer. I was also having to hard boot my computer off which we all know it not good for the computer. My computer was randomly freezing and the mouse and keyboard would become unusable. I was unable to use control alt delete. I was also having crash issues. The computer would randomly shut itself off and then would give me the error messages, corrupt files, possible bios issues, as well as dump files. There is a post on here in reference to anti virus conflicts, as well as posts about not letting the computer hibernate and keeping the screen saver off. I have reinstalled windows 7 3 times in the past 2 days. I set the computer so that it would not hibernate as well as turning the screen saver off. On my windows vista I remembered having a conflict when I had Macafee and windows firewalls both operating. When I reinstalled mcafee the system would not allow me to disable windows firewall. I believe part of the problem was a conflict with both security systems. This time when I reinstalled mcafee I did not select mcafee firewall to download. My computer seems to be running fine for the past 3 hours. We will see. I am running mcafee anti-virus for real time scanning email/internet etc but am using windows firewall.

Hope this helps someone else. I will keep you updated on whether or not this continues to work.
