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

    Hi

    I did not know how to make my own treaht here, so I just replyed. I have this random frezzes also. Getting very annoing. But I notices its happen diffrently when playing diffrenten games. For eg. when I play The Secret World, it rarely happen, the frezzing part. But when I play GW2 it happens randomly from 5-10 mins or more. I fix it by pressing ctrl+alt+delete and press start joblist and then my computer unfrezzes and i can use it again. Well its not my entire computer that frezzes, its my mouse that stop working. I can move around with mouse, but I cant click on anything, unless I do that ctrl+alt thing. I to, have a

    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.
