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

txtomcat(and everyone),

    While the Process Monitor is running, you can select several lines and then copy and paste them into the forum or into a text program. If you click on the save button it will save all the entries currently in the ProcMon window. It will default save it to the location that ProcMon was run from. When you open the log file it will open in a ProcMon window. Then you can copy the lines from a time frame when an issue was occurring. Below is a sample of what the text will look like.

unfortunately, The PC is having a bad day and booted to the desktop, just before the cursor started to stutter then it froze.

Wont even allow me to boot up in safe mode now.

gonna try and send it back to cyberpowerpc and get them to fix this.

I have this feeling that the HDD is going bad or gone bad and is just working too slow.

Hey all. I used the ProcMon program as suggested above and noticed nothing for the first 10-15 minutes and things were running fine. Then out of nowhere, wmpnetwk.exe started running. At this point, things started to freeze up and the symptoms that I have been having began. (slow if any response and memory usage spiking to 90% or higher) So I looked into it and it seems that it was an issue with some of the beta builds but was said that it should be worked out before the RTM. Well, here we are and it seems as though the bug may have found its way into my system. So, I ran services.msc from start>run and scrolled down to wmpnetwk.exe. I stopped the process then disabled it from properties. (it should be interesting to note that it was set to automatically start on a delayed schedule which could explain why we have had times where things were fine and then the problems came storming back) I restarted and immediately noticed a snappier feel and have not had ANY of the symptoms since. I should also note that if you share media through WMP or Media Center to your XBOX or another PC that this process is needed so only disable if you don't use it. I don't so I am okay. I really hope this works for all of us and that Microsoft pays attention to the bug.

UPDATE: AlexT from another forum http://social.answers.microsoft.com/Forums/en-US/w7performance/thread/be9c5622-de20-4c31-a5fe-23ee08580329 mentioned that disabling this process DID NOT prevent him from streaming to his XBOX! He says it still works perfectly.
