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

    All,

    Here are some items to try and some information we would like to know.

    Clean Boot your system and test.

    From the Action Center run the check for performance issues.

    Open the Performance troubleshooter by clicking the Start button, and then clicking Control Panel. In the search box, type troubleshooter, and then click Troubleshooting. Under System and Security, click Check for performance issues.

    If your system freezes, without going to a blue screen error, how do you get out of the freeze?  Do you have to reboot, are you able to reboot through Ctrl+Alt+Del or do you have to do a hard reset?

    Check the Event Viewer for any warnings or errors.  Specifically look in the System and Applications logs.  Let us know the Source and Event ID.

    If you are getting a blue screen error, what is the error code?

    Ok,

    I re formatted and reinstalled vista X64.

    I unplugged EVERYTHING but mouse and keyboard.

    I still get HUNDREDS of SVCHOST.EXE  but they resolve within about 1-3 minutes and I get just

    some sytem files running.

     From what I can tell, 99% of the SVCHOST... files are DLL files. Each different and "moving"

    quickly within the table.

    I have gotten a couple of "event 100,201" warnings for slow shutdown and slow start up.

    EXPLORER.EXE seems to be the culprit there.

     So far she is performing as she should. No updates of any kind installed. No sound drivers

    or graphics drivers are installed. Other than what came with the OS.

    Tommorrow I will initiate sound from MOB only and install WWll online from a disk. and play offline.

    This pc is not going to taste the internet for awhile.

    Question: is it normal for the OS to initially run SVCHOST...DLL files in such large numbers with boot-up

    (or just after)?    (I'm still getting them as before but they go away much,much quicker than before.

    Keep me updated Raikov, looking forward to seeing if you fixed your problem. (I have been up for nearly 45 minutes now without a lock-up.. this is a personal best so far.)
