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

Just an update on where I am at - fixed hopefully.

Had built a new i7 unit with Gigabyte GA-P55-UD3R, 2*2gb, Sapphire 4890, Samsung hd.

I was getting freezes all over the place. Updated every driver, bios etc.

Took out 1 of the 2gb of ram and all was fine, and found 1 stick of ram was faulty.

Even with the good 1 *2gb it frooze on large file transfers.

Also, found out the ram I had was not compatible - from the corsair & crucial websites.

RMA'd the 2*2gb and got compatible ram - 2*2gb again and was playing MW2 today.

initial ram - Corsair 4gb (2x2gb) Ddr3 1333mhz Xms3 Memory Kit Cl9 (9-9-9-24)

replaced with - Crucial 4GB (2x2GB) DDR3 1333MHz/PC3-10600 Memory Kit CL9 1.5V

Thanks to the folks who sugested I take out 1 of the ram, helped to solve it for me.

I have experienced the same symptoms on an OEM system with Windows 7. This hardware has previously worked without issue running XP Pro SP2 for many months but thought it worth trying the usual hardware fixes without any resolution to the freezing. I finally came to the conclusion that this was a driver/software issue with Windows 7 and have since reverted back to XP Pro SP3. I have stress-tested this for many hours using Passmark and have had no issues. To further prove this point (that it is a software issue) I have installed VMWare Desktop on this system and installed Windows 7 as a virtual machine. I used the same stress-testing software on this VM version of Windows 7 as before and it has so far been running for many hours without a single issue. The reason for this, in my opinion, being that XP Pro is touching the hardware and not Windows 7.

Let me make a point here, I am a keen advocate of Windows 7 and have been using this on my notebook for many months with no issues and nothing but good things to say about this operating system. I sincerely hope that Microsoft resolve this quickly and we can all get back on track with Windows 7 being an excellent OS and an obvious upgrade for all concerned.

If anyone at Microsoft or on this forum needs further information on my set-up then post here.

OK here goes again if vista 64 bit works why not 7 64 bit

why should all these users have to fool around with timing and even more to that lower their speeds for a fix

We will wait till after christmas when sales go down for a fix and when thousands complaint, might this be a sales strategy for hardware sales to go up or i could be wrong. (it's all intertwined for profit)

Anyways if i would have the fix i would post it , but i have tried it all and still have same issue.

Make the fix MS we will not buy more hardware if vista 64 bit works then why not 7 64 bit.

I would like to post a fix but we have tried them all, you know we are still giving this OS a chance and trying hard to keep it on our systems and it would be nice to tell all my customers maybe 100+ that windows 7 is stable and they should get it, but if am experiencing this issue i would not want my customers to go threw this, then i will get nailed for recommending it to them.

We are still hanging on for the fix or will it be back to XP

If i had a fix i would just post a fix but all these comments are related and are opinions because no one has a conclusive fix

I know it's a tough world in the so ever changing technology but it is really not up to us to be the beta testers and even have to struggle to make the fix
