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

I used to have slowness in XP due to WMPnetwk.exe soaking up the RAM.

I fixed it by clearing my torrent files of anything I wasn't bothered about. All the partially downloaded movies and such that weren't downloading. That fixed the problem for me. Seemed the sharing thing was trying to interpret a file constantly and was unable to do so because it was unfinished (my theory, by no means fact).

It would be interesting if the problem persists in W7. I haven't configured sharing yet, so I'm not sure if that's what it is. I suppose it would make sense, since the freezes only happened when I was on a network.

Disabling wmpnetwk.exe simply means to find Windows Media Player Network Sharing Services in the services.msc section and Stopping it, right? It stays stopped after that? And I can still stream to my Xbox 360?

Sorry that my advice didn't help you RBTaylor. I am still without problems but obviously there are a lot of bugs right now that are causing some crazy problems even with brand new pre-installed rigs. Glad to hear that the info I found from another user has helped you AzazelEnoch.

I disabled that service a few days ago, and it did not help. Long story short, I DID listen to him and I'm NOT done with this. What has helped, with me anyway, is dropping my memory speed from it's rated 1333MHz down to 1066MHz. Since doing that, day before yesterday, I've had no crashes. Not ready to call it fixed just yet, though. If I go another couple of days without locking up, maybe then.

You're all running close to the same hardware...not me. I'm on a Vaio notebook (VGNAR320E) and have been running WIN 7 since the first public beta. I've been locking up randomly for about a week now 6-8 times a day. I dissaabled the Windows Media Player Network Sharing Serivce and applied the hotpatch for good measure and my system is now flawless under a ton of stress. The hot patches are at the links up there and for god sake listen to the man and dissable the service. I seem to be the only one that did now I'm no longer having to worry about this anymore.
