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

This is interesting timing! Mine is W7 Home premium, and the problem hit at that time. Would lock up completely. Machine in warranty, took it back, they said nothing wrong, must be a peripheral. Checked all one at a time, no problem. Did it again, they said bad memory, replaced. Yesterday again sudden stop without reboot, but did not lock up, so I could restart. There are obviously multiple causes in this thread, but something went wrong in early April. I did check Intel site, and that said to download audio driver. (Realtek)

Passionfly1 was right, lowering the ram speed fixed it for me. I built a brand new Windows 7 x64 system with top quality parts and for weeks have been having random freezes and restarts, 20 or more per day. I tried everything. I ran performance tests - all okay; I swapped hardware; I uninstalled drivers; I changed settings; I stopped services; I monitored the event viewer - nothing. I was at my wits end when I scrolled to the end of this forum and read up to passionfly1's posts about ram settings. It was the only thing I hadn't tried. It was inconceivable to me that my XMP ram couldn't run correctly under it's own XMP profile settings. In the BIOS, I simply lowered the ram speed from 1600 to 1066 and that was it - a stable system. I am so relieved and so thankful to passionfly1.

I have the answer! (for me, anyway)

The removal of Microsoft Update KB980302 seemed to solve my problems with freezes on my Win7 64-bit platform!

Hmmm, well I show that update as having been installed this May (2010) and my issues were occuring long before may, so I doubt uninstalling this will help me.

I've tried disabling my second monitor as well, and froze with the second monitor disabled, so that is not the cause.

I've also tried to install the proper logitech drivers for my wireless mouse, but have frozen once since then. I am still not entirely sure it's not a wireless mouse issue, as the freezes always seem to happen just as I start to move the mouse.
