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

    If you are running other 64 bit operating systems fine that utilize all hardware then YOU DON'T have a hardware problem. It is silly to jump to conclusions. Not everybody has the same issue (that's why they should be logging their issue on seperate threads).... don't expect this thread to get anywhere (too much noise).

    That's true but I did not experience sudden restarts until Win7 came about all along having a bad memory timing issue lurking in the background cause me to confront these hardware problems which Windows 7 detected rather violently. If Linux or XP are not showing the symptoms but Windows 7 does maybe its a sensitivity issue of the OS in detecting these off-kilter timings. But the short end of the story is I did have a hardware issue that once fixed made sudden restarts stop completely and my computer is running very nice and behaving and i love it!

    If you think Linux is less sensitive that Windows 7 you've got another thing coming LOL :).

    This probably fixes YOUR issue as YOU hard a hardware related issue and decided to visit a Windows 7 forum with your hardware issue ;)

    I have no hardware issues thankyou (I've been building PC's since the early 1980's).

    Not all the issues here are like yours if you read the thread carefully. And people have been going on about memory timings before. Again if they have hardware issues they should goto TomsHardware.com :).

    It wasn't just "my" issue but many identically Freezing/sudden restart issues or BSOD/CTD on this forum, on many other forums and with my friends. For you to point at me and say this is positively NOT something to be investigated on a PC having these problems is ridiculous. I am not here to offer help and be confronted by such logic. Just because it may not affect your system does not discount that it is a root cause in others, however. And I too have been building PC's since the mid-1980's and my Mom can beat up your Mom, so how does this help the people with problems on this forum?

    Please stop taking these posts as personal attacks against you, your knowledge of computers or anything else personally. I am not being paid here to offer help and neither are you so lets remain civil and discuss ideas without getting into the whole superiority complex side of who is better at computers then whom. Because frankly when u started tinkering with PC's is irrelevant since Windows 7 was not out at that time.

    "Again if they have hardware issues they should goto TomsHardware.com :)" - no one should be told to go elsewhere for anything and you are not the internet police to suggest that. This is the forum for Windows 7 issues whether you like to think so or not.

    If you are going to contribute to information here please do so so it helps someone not attack ppl for offering proven suggestions that have fixed identical problems and should not be dismissed offhand.

    I really hope a fix is found soon as this is becoming annoying as I am unable to use my computer properly and certainly am not making any use of my new quad core processor and Direct X11 gfx card, maybe I will stick with Linux if it is stable and use Wine until M$ eventually release a fix Win7 SP1 anybody?

    if you have a hardware problem in your PC how exactly is a service pack going to help you to correct a hardware issue of incorrect memory timings in relation to your Mobo? I am not saying you have one but do u see how silly this statement is if ppl have their memory timings set wrong or incorrect voltages for the memory speed. Or even memory speeds too fast for the processor they have. A service pack wont do jack to help these issues.

    What would help is if Microsoft creates error codes that are aren't meant to be read by ppl with Computer Science degrees but normal ppl who have some base to work off of to tackle these errors. THAT would help everyone.

    My memory timings where wrong for Vista 64-bit?  Please explain that, I ran solid as a rock under Vista and my memory timings are the same now as they were back then.  

    But then along comes Windows 7 and suddenly I am subject to random freezes.  The cause is Windows 7, not my hardware.

    my timings were the same back then under XP and it ran solid. Look you can bury your head in the sand and offer conflicting arguments but how does this help anyone to to check if this is the case in their system. Myself and many other people have resolved their sudden freezing or restarts by fixing the memory timing issue. Are you claiming that we haven't and just going to say its NOT the cause and we need to keep doing further pointless tests?

    Do you have an actual proven resolution to this issue instead of dismissing this may be the cause? If so, I'm sure the focus should be directed there and not dismissed so easily.
