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 happen to have an asus motherboard as well (780i), and I can confirm it has one of the most tempermental memory controllers ever. I simply cannot run my 800mhz ram at its EPP timings (which are 4-4-4-15) for very long, and I have to use its default SPD timings to eliminate random freezes (6-6-6-18). 64-bit seems to bring about this issue more.

So if anyone is getting random freezes (especially with asus), try the memory timings and/or memory voltage first.

Hi everyone, I was having the same problems as all you guys after upgrading from Windows 7 home Premium to Windows 7 Ultimate.

Lots of bluescreen and black screen crashes all quite randomly.

Luckily i made Factory default discs before upgrading to ultimate, I restored the system back to Windows 7 Home edition, and then upgraded again to windows 7 Ultimate,now everything is ok no crashes at all, the system is fine.

Some of the programs i installed after the first upgrade were not compatible with windows 7 ultimate, and were the main cause of most of the troubles,the main culprit was a html editor called Arachnophilia.

I have re installed that from the home website and now it runs ok on windows 7 Ultimate, and no more troubles.

Regards to all

This problem is so annoying. I have had since I did my install of 64 bit W7. I have tried every tip suggested here and everywhere with no success. I believe it has to do with hard drive access but I can't prove it. Anybody have any new ideas?

Step -one: Antivirus Test

You'll be able to quickly uninstall your personal computer basic safety computer software temporarily and then test the boot/computing efficiency. If your Windows 7 freezes even soon after removing the antivirus method then it can be extremely probable that there are registry errors leading to this queer issue.

Action -two: Registry Restore Take a look at (Suggested Stage):

What leads to computer systems to malfunction is frequently connected for the corruption in Windows registry which is actually a data source that outlets all the information about laptop or computer products, software package and hardware. Working a registry restore scan with an efficient registry cleaner and PERSONAL COMPUTER optimizer software program can definitely increase Windows 7 effectiveness and fix freezing challenge within your process.

Factor -several: Startup Fix

The plans that begin when your laptop or computer begins are referred to as the startup software programs or things. Too numerous startup items can potentially freeze decrease your computer system. To lower Windows 7 freezes and lags simply type "msconfig" inside the Windows Quest. A process configuration utility will appear and you also will have to click on around the "Startup" choice. An inventory of plans will display up under this selection. You may disable or enable software programs to tweak up the Windows 7 effectiveness.
