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 have been following several of these posts related to Win7 freezing. Have tried everything that has been suggested without success until now.

My system is a fresh full install of Win7 Ultimate x64, OEM system

I have noticed the following issues in the event viewer that occurred 3 seconds before the freeze. I have tried disabling the screen saver and power saving (keep monitor and hard drive always on), and while disabled I have had no freezes, but when re-enabling screen saver or power saving, the freeze re-occurs frequently.

I will keep monitoring the system and report back, but so far, as long as the power saving is totally turned off, and no screen saver enabled, no freezes!

Let me know if anyone else has or will try this.

Sorry it didn't help Tim. I'm sure there are more bugs than anyone can even imagine.

Disabled wmpnetwk.exe and no difference, still freezing regularly. Better post this quickly before it does it again

I have this random freezing problem on a new build Dell XPS 13 running 64 bit Windows 7 Ultimate retail version.

There are no peripherals attached, only hardware supplied by Dell.

I was capturing output from the process monitor but the freezing of the laptop corrupts the file so I can't read it.

I did a clean boot ensuring only Microsoft services were running.

Machine rarely will run for 30 mins before freezing.

There is no blue screen and nothing in the Event logs, (I guess nothing has a chance to get written to it).

I'm worried now as have just had 36 new Dells with W7 delivered. I will delay deploying these until this is resolved, (or install Vista).

Troubleshooting this is almost impossible, theres nothing logged and the only thing I can think of is to start stopping services one by one and waiting.
