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

    Fixing the ram timing fixed my random freezes.  Thanks for the suggestion.  The motherboard set my timings to 7-7-7-20 when the ram called for 7-7-7-18.

    If your computer now runs more reliably with the 7-7-7-18 memory timing than with the more conservative (less likely to give problems) 7-7-7-20, I'd say that this is wierd.

    Or maybe I misunderstand.

    Removing TDM - Trusted Drive Manager fixed my computer.

    I have a Dell Precision T3500 Xeon W3520@2.67 (same as I7) with the VelociRaptor Drive, and Windows 7 Ultimate - 64 Bit.  I have had lock up problems since I bought the computer over 2 years ago.  The freezes allowed me move the mouse, but constantly gave "Not Responding" messages with the spinning cursor on every application window while the hard drive ran constantly for no apparent reason.

    Looking in the "Informational Events" of the "Reliability Monitor", every time I restarted my computer I was getting 211 "Successful Application Reconfiguration" messages.

    Since I removed TDM - Trusted Drive Manager on May 10, I haven't had a single "Successful Application Reconfiguration" message, and not one lockup.

    There were also some Windows Security Updates on that day, but I doubt that was what solved the problem.

    I don't know if I am losing anything by not having TDM running, but at least I am no longer losing my mind.  I don't know how many people have this on their computer, but removing it worked for me.

    I just downgraded to an old copy of vista 32-bit i found lying around and my computer worked fine for about 8 hours of playing games and being left just on the desktop before crashing. It seems to be better now i am not on Windows 7 but the problem is still very much there and pops up on me every now and again. I am really lost as to why this is happening now, if anyone could give me tips on how to find out what is wrong with my PC i would be very grateful thanks.

    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.
