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

it is a desktop computer. I ran the checkdisk but there was not a problem. Sometimes for ten days i have not met with this problem. It is totally random. i ran the asus diagnistics aoftware to test the system and it did not find any problem with hardware.

yeah i am using messenger 2011. In my cases i did not even open the msn messenger. I think another thing causes that problem.

What do you think about the chance of a hardware failure?

Hi tekinalp67,

Is this a Laptop or Desktop Computer?

Maybe not a Hardware Failure, per se, but maybe a File System Failure.

Have you ever ran a Complete Chkdsk with both options checked? You need to schedule and reboot to run.

A 50 GB size partition takes about 30-1 hr to run.

This is why you want to have the operating system's partition small in size.

The larger the partition, the longer it takes to run chkdsk.

I have My Documents on a separate partition.

My computer has 64 bit Windows 7.

It has i5 CPU

1 TB Harddisk

Asus motherboard

XFX ATI 6950 graphic card

My computer goes to black screen randomly, while playing games or surfing over the net. The sound get into a loop. I have to reset the computer.

I could not figure out what is the problem. I make tests by the asus diagnostics tool but it did not find any problem on the hardware..

Hi All and tekinalp67,

Does anyone have Windows Live Messenger 2011 installed? See what happens, if you uninstall the program for a week.

I have noticed that it always freezes / Not Responds when signing in.

This program may be the offending program, because some aren't using this program and I don't think that they are experiencing the Freezing problem. Though, I may be wrong.
