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

    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.

    this question is best posed to Microsoft as to what those service host processes are doing but it does not sound reasonable at all to have that many. Something is seriously wrong with the OS to cause all of this.

    Having the same problems as all of you as well. Computer will randomly freeze up anywhere between 5 minutes to 1 hour or so. Havent found anything that I can possibly call as a clue to why this is happening. Just upgraded to windows 7 last week, and everything worked just perfectly for a few days. I then loaded up Heroes of Newerth and played for approx. 30 minutes before I got my first freeze-up. Now the freezing has not stopped. All CPU, GPU, ACPI temps are normal. I feel as though the only hardware that could be causing this problem is my Power Supply, But I am not even sure if that is it. My northbridge fan is not spinning, but that is probably not the case for this problem to be occuring.

    Here are my specs

    Intel quad-Core Q9650

    Asus P5N-D Motherboard

    8 Gigs Ram DDR2

    2 GTS 250 Nvidia Vid Cards

    I know we are all experiencing the same problems.. so any help would be amazing.

    also just to add, I have frozen in safe-mode.. multiple times. I do not feel as though it is performance related because it will freeze even if I am idle on the desktop screen. Nothing seems to trigger this problem.

    I am using Avira Anti-Virus, idk what else to state... Ill edit if i think of something.

    Its your memory stick timings, voltage/frequency that is the cause here if its crashing in Safe mode. i can almost bet my life on it.

    I´ve done some more tests to fix the problem:

      -Changed my power settings (no effect).

    -Updated my drivers. I don´t know if all drivers is up to date but I´ve installed the latest drivers for sound, and graphic card. Windows can´t find any new drivers (Didn´t help.).

    -scanned windows system for false files. (No finds).

    -Defragmentation. There was nothing to defragmentat since I Installed Windows 7 less than a week ago.

    -Disk Space Cleanup Manager. Removed old windows files (no effect).

    -Cleaned registry with CCleaner (thought it helped but it didn´t).

    -Cleaned registry with Registry Mechanic (Didn´t help).

    -Stressed my graphic card with ATITool (no error during 15 minute test)

    -Stressed my CPU and Memory with Prime95. (After 45 my computer freezed)

     

    I don´t know if it is something with the Motherboard, CPU and Memory or the usual freezing just interrupted my stress test. I´ve not mention that sometimes when freezing I get some weird sound coming from my speakers. It´s a high pitch sound playing in loop when the computer freezes. This is mostly happening when I watch movies or listening to music. I think it´s just the last sound before freezing that´s in loop. It´s kind of like 'Screech of Death' but I don´t have a Creative Sound sound card.

    Asus P5Q3

    Intel Core2 Quad Q9950, 2,83Ghz

    4gb DDR3 ram

    ATI Radeon HD4890

    Windows 7 Home Premium x64.

    Edit: I runed the Prime95 again and this time for 11 hours. No error.

    you must bump down your memory timings, frequency and voltage to get a smooth system with this software OS problem. Its the only way until Microsoft gets off their lazy as s es and fixes this c r ap. >.< I am running my system memory at 800mhz when they are premium modules specced to run @ 1066mhz. Stupid Microsoft. They don't care about us just the bottom line in their dumb paychecks. =P

    Ive also tried alot to fix the problem without success. I changed my power settings, update drivers, etc.  Last night i did cleaning of my registry with CCleaner. My computer didn´t freeze until a few minutes ago. Thought it fixed the problem but no. Today it even shut down the computer by itself. Was writing on my essay when the screen turn black and the computer rebooted, weird! Then I opened Spotify and didn´t even get to the welcome screen when the computer freezed again.

    Asus P5Q3

    Intel Core2 Quad Q9950, 2,83Ghz

    4gb DDR3 ram

    ATI Radeon HD4890

    Windows 7 Home Premium x64.

    this is definitely the typical example of how the situation happens. It's the memory timings for sure. Once your memory is bumped down to lower frequency and correct voltage this problem goes away. Its an OS issue for sure not a hardware problem. I've had enough experience with this problem to be 110% certain of that fact.
