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

    I spend thousands of dollars on a PC with windows 7, it works great for months (say 6).

    I literally have it sitting there, just serving media files and it starts freezing them. I have not made any changes to it. Now my expolrer.exe constantly freezes. The only thing I've witnessed is the PC updated itself and restarted. And is now virtually useless.

    Look at this horrendous thread, I have to be some memory timings expert? Have to look up RAM timings sequences from a motherboards website. MS is so out of touch with usability and design. You'd think they'd get it right after all this time. Nope. The amount of useless features cram packed into windows that people never use, if they put all those man hours and effort into making a simple OS that worked everyone would be a lot better off.

    I thought i might have a bad HDD or something, except I've troubleshooted and ruled out the HDD's, I then discovered that thousands of others are having similar issues for one out of a thousand different reasons. Seriously who can be stuffed having to research every intricate working of a PC, like every element to troubleshoot it, I think people could just learn to write their own OS after the amount you need to learn to be able to trouleshoot this product.

    Hey buy a PC with Windows and welcome to the land of having to learn a bunch of inane  technical jargon so that you can get use from your investment. Hah great selling pitch. I (we) are all such suckers.

    I knew I should have bought a Mac.

    Hi Everyone,

    The solutions provided here are all great, however I must emphasise that they all seem to have been caused by different issues; my problems for example have been fixed by building myself a new computer using up-to-date components, whereas other solutions recommend changing settings or even uninstalling third-party software.

    Just so everyone knows but you should try installing Windows 7 SP1 and see if that helps: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=c3202ce6-4056-4059-8a1b-3a9b77cdfdda

    Also try using the complete backup option in Windows 7, and then performing a clean install of Windows. If your problems go away then you know it was third-party software causing them, but if they still exist then you know it's a hardware setting or hardware issue at fault.

    The first step to troubleshooting is finding out what is not causing the problems.

    Re:  Random freezes with windows 7 – 64 bit

    Hello, Everybody!

    I used to have the same problem for a long time; first, with Vista Home Premium 64 bit and after, with 7 Professional 64 bit (Upgrade), I tried hundreds of possible solutions to the problem and all of them failed, but I noticed that the most of the times at least one security program was involved in it, so I focused my struggle on them.   Finally I discarded my G Data, Counterspy and Prevx (just a few days after the license renewal) and I stopped my SUPERAnti from starting with Windows (I start it manually every day a little while after starting Windows) and now I don’t have any freezing problem. 

    I don’t know if each of those antivirus and antispyware caused the problem by themselves or if it was the combination of all of them (and other apps.) together, possibly a kind of incompatibility?   But now that I’ve been using Avast IS, Malwarebytes , Windows Defender and my SUPERAnti, the only change made to my system, it’s working perfectly well.

    Another thing that seemed to help a lot was stopping Windows Defrag and Backup and Restore of running automatically, in order to avoid that they could run at the same time that an antispyware or my antivirus scans.  First, I tried insistently to schedule everything in a manner that they didn’t run simultaneously, but there was always something to make them coincide sooner or later, so finally the only secure solution was using those Windows programs manually.

    I’m really sorry about my Counterspy because it’s very good, but I haven’t finished making my defenses combination.  I will re-install it soon again and see what happens.  Probably I’ll have to disable my Windows Defender, but if it works right this time I win.  The next one to be added (let’s say a month after) will be TreatFire.   But I don’t know if too many security programs could be part of the problem (or the problem itself) that’s something else that I will find out this way.   I’ll let you know the results.

    One more thing for 7 users (if using screen saver):  I suggest you to test how your computer works with and without screen saver.

    Still having freezes here too. Thought the windows update helped but... alas.

    I will say the incidence has slowed down a bit tho.... but Im guessing thats more of a fluke than anything fixed.
