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

Hi everyone, I am experiencing random freezes as well:

I just bought a brand new Pavilion DV7 3080-uS 4 weeks ago. My computer started to freeze up about 2 weeks ago now.
- Operating System: Microsoft Windows 7 Home Premium 64bit
- Processor Name: Intel Core i7-720QM
- Processor Speed: 1.6 GHz
- RAM: 6 GB (2+4)
- Weight: 7.5 lb
- Screen Size: 17.3 inches
- Graphics Card: nVidia GeForce GT 230M
- Storage Capacity: 500 GB (7200 RPM)
- Networking Options: 802.11n
- Primary Optical Drive: DVD+/-RW DL with Blu-Ray
It is really frustrating as I am sure that HP customer service won't be able to help and as I have no idea where it can come from.

All the software is up to date, windows updates are up to date, my anti-virus is Microsoft Security Essentials, HP doesn't find any new updates as well.

It can freeze when Im playing games, only using IE8 or google chrome, and lately every time I watch movies with WMP (sometimes I still have the sound, but nothing else is moving and my keyboard doesn't work)...

Sometimes I can't even run safe mode, because it freezes while booting, sometimes I turn my computer on and nothing happens (blank screen).

The most annoying is that my computer is only 1month old and that I feel that I am destroying it with all these "hard reboots"...

Please someone help us...

Thanks.

I'm also experiencing random freezes. It's really frustrating because I'm running RAID1 and it takes an hour or more to complete verifying. Arrh!

Brand new system:

Windows 7 Prof (Freshly installed three times)

Intel i5 CPU

4 GB RAM GSkill

P7P55 Asus motherboard (latest BIOS 711)

ATI 4650 GPU PCIe with latest driver

two Samsung HD 300GB

three cooling fans

I'm not using a 1TB drive and still got freezing - assuming it was the same issue as mine I doubt if thats the problem.

Did people disable Windows Media Player Network Sharing Service?

Did they try taking out their sound cards to see what happens?

How about changing their NIC card (of if it's onboard putting in a new NIC and disabling onboard).

Did they try upgrading their sound drivers/ NIC's?

If they are getting blue screens (nb the main thread issue here is total freezing not blue screens) are they using WinDBG and VERIFIER to diagnose the dump file?

I seriously hope it's not an issue with Windows 7 not liking 1TB drives.

Mostly because I was going to get a 500GB for my new build, but decided to just get a 1TB on the reasoning of "Why not?"

Still, if that Is the problem, I'm sure it's fixable...eventually.
