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 hope MS does not start to tie OS with mobo for some peculiar reason or at least make it seem that way.

Come on MS give us that fix don't let us figure it out, it is your OS not ours why should all these users go threw this, if something is not working on your OS properly, a feature or service let us know give us the work around.

I know you have the solution.

Anyways why do we have to take ram out

It is an issue with OS and nothing else if XP works fine then why not 7

If you want to run Windows 7 on your PC, here's what it takes:
- 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
- 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
- 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
- DirectX 9 graphics device with WDDM 1.0 or higher driver

HI,

Have read this whole thread over the last few days and got a lot of tips etc but none really worked.

So today - I decided to take one of my 2gb (2 * 2gb) out and see what happens - and no freezing at all.

was running for 3 hours and no hangs. haven't put the 2gb back in yet.

decided to double check on the compatibility of my memory and my mb, which I 100% thought I checked before ordering.

and to my surprise - it's not compatible.

not sure why only 2gb runs fine and 4gb hangs it - but am ordering 2*2gb of different memory today.

hope this helps.

The freezing has gotten worse over the past two days to where it has now frozen (aka Hard Hang) 3 times during start up. I have to do a hard reboot. I did notice something really interesting though. The icons on my desktop move around from before the freeze to after. I noticed (and read some other threads) where the recycle bin was moving around from one start up to the next -- staying in the same general position, just moving up a grid section or another. Personally, don't leave snap to grid on, but I do use it to align everything, then uncheck the box. Well, this time my file icons reverted back to the location they were a while back.

This is an odd little thing, but hope this helps us understand what might be going on behind the scenes to make these hard hangs happen. I have not had any updates nor installed anything new in a couple of weeks,and all of a sudden the hangs are happening much more often. I don't even have a dump file because of the way things just stop working. My productivity is shot until this gets resolved...

I have random freezes with Windows 7 ultimate 64bit. I get a weird noise from speakers and no power on mouse and keyboard. All this when using 4gb RAM. When I remove one dimm everything seems to be fine. Also had the problem when installing. It doesn't matter which dimm I use or in which slot I put it. I had a LiveCD Memtest running overnight for each dimm and for both and no errors occured.

System specs:

CPU: Intel i7 860

MB: Gigabyte P55 UD4

GPU: Nvidia GTX275

RAM: 4GB (2x2GB) Corsair Dominator 1600

Also tried to set maximum memory setting to 4096 manually from msconfig>boot>advanced while on safe mode. Didn't work.

Please, any help would be nice.

Thanks in advance.

I have the same issues with Win 7 Ultimate X64 no matter what I tried it will hang and freeze mouse key board applications the lot I'm absolutely disgusted with MS.I ran RC of Win 7 on my other set up (P35 chipset) no issues what soever so I tried it with My purchased copy of Win 7 Ultimate x64 and it's been running a whole week with no issues just as it did with the RC version

Gigabyte P35GADS3L

4g Transcend

Core2 duo E8400

ATI Radeon 2400 Pro GPU

Realtek High Definition Driver Version 6.0.1.5973

latest INF file from Intel

all the latest applications

Firefox 3.5.5

Everest5.30

Skype4.1

logitech web cam

Kaspersky INS 2010 runs like a Swiss watch

now the exact same but a new Mobo

ASUS P7P55D Deluxe

i7860

HIS ATI Radeon 5870

Corsair 4g GT DominatorC7

Ran like crapp sent a RMA for the Mobo with the supplier they will test it out ,hope they find what MS can't or have they but to chicken to spill the beans if board comes back ok and I still have issues then I will seek compensation from MS as product is not performing as claimed and give intel there i7860 back and Mobo back to retailer cause it will be all incompatible with each other and swap it for something different like a good Mobo on LGA775 with DDR3 compatibility and keep my E8400.
