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

    I found  the exact problem that causes this freezes. My computer freezed today at 20:17. I went to the event viewer and found that at that time there is an event says that "The DgiVecp service failed to start due to the following error: The system cannot find the file specified."

    Is there anyone who knows about it?

    Thank you.

    This is about total freezing as i have the same problem. I did notice something about this issue though.

    I have 2 (identical) Dell pc's that run the AMD single core Sempron processors. Both have Windows 7 x64. I think i have it nailed down to 3 possible things for me. I installed a phenom II x2 in one of them, and there is no problem. Then I put a ATI 5770 card in the one with the phenom and it freezes like crazy but randomly. I took out the HD and put it on the other pc without the upgrades and it boots and runs fine. I then put the not upgraded HD into the upgraded case and it does not freeze, until it recognizes the Vcard and tries to update, then it starts freezing also. now both drives freeze on the phenom unit. I take them both to the pc with the sempron cpu and run a registry fixer and that lets me run on the upgraded one again, but i must ignore updates to keep it running. If i take out the Vcard after it starts freezing, it does not help. I do have a cheap 800 watt PS on the upgraded one (starting to make me wonder). both HD work flawlessly when the sempron cpu is put back in instead of the phenom, no crashes at all, ever. and the non upgraded one works perfect with only the phenom processor (no VC or upgraded PS). I don't get it.

    This is what mine has been doing for months - always when watching YouTube videos in IE or sometimes while watching stored video files.  Computer freezes up with loud robotic buzzing sounds from the speaker, and will resume after a few minutes.  I tried formatting the PC, no help.  I've had this laptop running Vista x64 for 2 years in March - the problem started about 6 months ago, so apparently there is a software update or something conflicting causing this to happen.  I'm thinking about another Mac at this point...

    Good to know that I'm not the only one. I tried rolling back my flash player, but then I stated getting incompatibility issues...

    Sometimes when I play certain flash games my screen gets all crazy, but it only does that with one in particular....and other times, freezing.

    Could flash player be the culprit? But I get freezes when I watch dvd's as well.

    So I don't think dealing with the network manager will help, but I'll give it a shot.

    Hi All,

    Try using Windows 7's Wireless Network Manager, rather than using your Adapter's Network Wireless Manager and see what happens, when connecting to your Router.

    The problem might be in the Wireless Manager posters are using, rather than the Browsers themselves.
