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've been searching for weeks on this problem and there are no answers, everybody just has guesses. I want to know why this product hasn't been recalled or how to get my money back. I am sick to death of my laptop freezing once a day, and of course because my off button is software controlled I can't even reboot without unplugging it and pulling the battery. Windows 7 is clearly defective (I actually like it otherwise) because the entire operating system shouldn't freeze when there is a problem with one component somewhere. That is like my car shutting off on the freeway when I get a warning light. This self diagnosing and endless waiting for the next upgrade to fix this wouldn't be tolerated in any other product. Windows 7 came preinstalled on my laptop, but that does not mean it was free, the cost was worked into the price I paid - and I want to be compensated before having to switch to Linux.

If anyone knows of a class action lawsuit we could join I would be very interested in joining.

I have download the hotfix and my computer has not crashed in the past 24 hours or so. I am going to leave my computer for the next 3 days running and I would like to see if the hotfix helps or not. My computer has frozen up on me even during idle

The sad fact is, I've given up on Win7. I've got work to do and it doesn't include bug-fixing or beta testing for Microsoft. I'm going to UPGRADE this machine to XP Pro SP3. I'll consider Win 7 again AFTER they've released a service pack (or two).

I am having the same issues... it is freezing at 3 mins 30 seconds from the Windows start up screen. It has been fine for just over a week and now I rebooted at least 7 times this morning alone. So far, the onlky time it has NOT crashed is when I have run the system in safe mode with networking. Go figure.

I cannot do 3 mins of work and pray that I get it saved before I reboot.

I initally thought it was my Microsoft wireless keyboard and mouse but it now doing it with wired devices.

I have done a safe start and also a system restore

We neeed a fix for this not just hap hazard band aid measures that may or may not last.
