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 random freezes with Windows 7 ultimate 64bit. I get a weird noise from speakers and no power on mouse and keyboard. All this when using 4gb RAM. When I remove one dimm everything seems to be fine. Also had the problem when installing. It doesn't matter which dimm I use or in which slot I put it. I had a LiveCD Memtest running overnight for each dimm and for both and no errors occured.

System specs:

CPU: Intel i7 860

MB: Gigabyte P55 UD4

GPU: Nvidia GTX275

RAM: 4GB (2x2GB) Corsair Dominator 1600

Also tried to set maximum memory setting to 4096 manually from msconfig>boot>advanced while on safe mode. Didn't work.

Please, any help would be nice.

Thanks in advance.

Same problem here. Runs fine in safe mode but it freezes everytime i go into regular windows. Sometimes i can get 10 mins out of it if im lucky. It starts freezing the active program then the whole thing eventually goes under.

Really frustrating >.< ive been fighting this all night long thinking it was a bad driver or or process. I disabled everything with MS config except for the microsoft stuff and still no dice

Hi I have been having these same random freeze issues for well over 4 weeks. While browsing the internet. When I put in a USB key. While trying to open a powerpoint presentation (one on which I had worked for many hours without trouble) on the day of the presentation- no joy. Needless to say I am a bit miffed. It is really frustrating because this laptop is so new and should be compatible with 7. I have updated the drivers to the best of my ability, installed the USB hotfixes and updated my NDVIDA software...

Lenovo IdeaPad Y430

Intel Core 2 Duo P7450 2.13Ghz

4GB RAM

Microsoft system management BIOS driver version 6.1.7600.16385

This really sucks. I am only posting this here so that I can add my voice to the clamor and hope that Microsoft notices.
