Random freezes with windows 7 - 64 bit

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

    The supposed hotfix does nothing. My computer continues to crash as usual.

    I've had random freezes myself since september 27th 2010, and they started coming in a very random pattern. I could be browsing the internet, the laptop could be idle, I could listen to music, play a game, watch a video, open a folder. Anything. It has frozen a few times during boot up too. I remember there was a Windows Update that day. I removed that to try and see if it would help, but it didn't. 

    Ever since that day I've tried countless things. Removing audio and graphics drivers. Tried beta versions, downgraded to old versions. Tried the same with intel drivers and wired LAN driver etc. etc. You know the drill. Have reinstalled the OS twice, no change. 

    It's not related to software, I think, as it has happened on a clean boot and nothing touched within 5 minutes. 

    Earlier I updated my BIOS, so far no freeze. But I'm not holding my breath, I've been fooled many times already by my own faith in my amateur computer skills. 

    Tried the power settings, no change. Tried without internet, no change. (As it has also happened at boot start ups.) I don't think it has happened in safe mode, I'm not sure I remember. I sincerely doubt it is RAM problems, I don't overclock anything. I have plenty of space, more than 250gb. 

    As you can guess, defragmentations, memtests, chkdsks etc. say nothing, do little and don't help. 

    EventLog says nothing besides the Kernel Power critical error, because I hard boot my laptop.

    I quoted you because I funnily enough also tried to apply that hotfix october 8th, and froze again sunday / monday 10th and 11 october. It worked a bit though. 

    I hope there will be a solution to this. This laptop is 2½ months old, haven't barely moved it from my desk really, I really really really really doubt it's my motherboard or hardware issues. But hey. 

    It's an Asus G60JX, with an intel core i5 CPU M 430 @ 2,27GHz (4 CPUs), ~2,3GHz

                                 4096MB RAM

    I have a Realtek audio card, and some silly Creative Audigy Advanced HD. 

    I don't have much of a clue when it comes to specs, don't kill me please. 

    I might try and go for the good old XP at some point. :)

    Solution for some found

    I used to have the same problem (random freezes with W7 64bit), I tried everything to no avail, but then stumbled across the solution. Since I applied the fix I havenot had any freezes (about 3-4 months now)

    This will apply to anyone using Malwarebytes with realtime protection on. What you need to do is allow exceptions in your antivirus software (MSE in my case). I am not sure if it works with other anti virus but for those using MSE together with Malwarebytes both running realtime protection this could well be the cause of your problem. In my case it solved it 100%.

    Of course for antivirus you should never have two progs running realtime protection at the same time, but Malwarebytes is not an antivirus program, it's designed to compliment your main AV. As such, and according to the manufactures it's possible run it in realtime along with AV. If you are using XP the exceptions to type into MSE are essential, but it seems they are also necessary for W7.

    I have to dash off to work now, but if anybody fits what I wrote above reply to this and I will list the exceptions you need to put into MSE.

    Hello everyone.

    Im running with following hardware:

    Asus P6T

    Intel Core i7 920

    Kingston 6gb 1333 kit (KVR1333D3N9K3/6G)

    Nvidia Geforce 470 GTX

    I used to have random freezes (randomly freezes for 10sec- few minutes). What i did was i upgraded all drivers and even bios.

    I checked the memory timings for kingston components, tried forcing 1333mhz in bios without succeeding at all. Random freezes persisted.

    As last act before downgrading back to vista 64-bit, I forced my setup down to 1066MHz from 1333MHz. Miracle: My setup worked of a lot faster and with no freezes at all. Been running all good for a week now. Not the slightert glitch. General FPS in 3d accelerated graphics and gaming also improved. It seems that my setup works far better with 1066MHz than it does 1333MHz. Im planning to try different memory components and see if i can get my setup working at 1333MHz.

    Hope this helps. The problem was a pain in the rear.
