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'm getting freezes with 7 32 bit. What I see very much in common is that the vast majority are running Asus motherboards. I'm running an amd 64 3500+ on a Asus A8N-E motherboard with 3 gigs of ram and getting total system freezes at times where I can reboot or power off, I have to turn the power bar off. I never ever had a single crash running Vista 64 bit. I don't use this computer a lot, I'm on laptop most of the time with is running vista. Was thinking of upgrading my laptop to Windows 7 but I'm gonna hold out and see how this plays out and how widespread it is. I don't have a lot of time to be messing around with a new operating system epecially if it's not relatively stable right out of the box.

I just downgraded to an old copy of vista 32-bit i found lying around and my computer worked fine for about 8 hours of playing games and being left just on the desktop before crashing. It seems to be better now i am not on Windows 7 but the problem is still very much there and pops up on me every now and again. I am really lost as to why this is happening now, if anyone could give me tips on how to find out what is wrong with my PC i would be very grateful thanks.

Similar problem - 64 bit Windows 7 Premium (final) - Freezing at random points generally with sound/video.

Reinstalled media player - no good.

My hunch is that there is something wrong with the sound drivers or CODEC's supplied. Probably sound drivers - I have a sound blaster audigy 2 as well. Freeze happens if I use Windows 7 drivers or unofficial Creative drivers.

Total bummer anyway... I have no choice but to do hard resets.

I have a 3.2Ghz Pentium IV (640) - hyperthreaded.

Motherboard:

Intel i925X chipset

Southbridge = 82801FV ICH6).

Also have ATI Radeon X850 XT Platinum Edition.

Dell branded (XPS Gen 4).

NB No problems with Windows XP Pro on same machine.

I have had similar problems as most people are describing. One thing i did notice, was just after the freezing stopped i opened up the Task Manager and checked to see if there were any memory hogs for certain programs. I usually run Firefox as a browser and this was using 800 Megs of ram. every now and then the internet browser seems to suck up a tonne of memory. Once i terminate the application, there are no more freezes.

Now and then it still freezes up, and every time it is related to the web browser. May just be an isolated case i have but. Check it out on your end.
