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

Update: Still the same with underclocked CPU and Memory.

I have no antivirus software exept from the malware detector from microsoft... and my OS partition is only a month old.

I want to confirm that this is a win7 so I downloaded Ubuntu last night and set it up.

Been running nice and smoothly for 12 hours now. Wait and see...

Will let you know. I might use Ubuntu for web browsing and watching movies and use windows just for gaming... It's a pain in the **** but this has been driving me crazy for the last 12 month and I cannot understand what is wrong!!!!!

Now the only thing I want is a computer that doesn't freeze...

I had the same problem with a windows7 professional 64-bit OS that I installed on my lenovo. I upgraded from vista home premium 64 bit, so I suspected driver incompatibilities.

I turned off my sound driver and synaptics touchpad drivers and I've been on for 4 days so far without a freeze. I'll go back and turn one one and then the other to narrow it down further.

Hope that helps someone

It took me forever but I found something that worked for me. I did everything I found in these threads, but none of it worked...I was going through my BIOS settings "again" and I noticed there was a GPU setting in the BIOS outside of Internet Explorer when booted up. I disable the GPU setting "in the BIOS" and I have been 100% freeze free for 2 months. It is definitively gone. The only other thing I did was make sure in my BIOS all my drives are in the right boot order and not set to disables as well. Definitively look for a GPU setting in your BIOS.
