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

mihaicosmin,

I found that amd had a new 64 bit driver on their web site that seemed to help my ATI Radeon HD 7500 series graphics card. I would check the AMD site as they have one dated June 16th, 2010.

http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx?type=2.4.1&product=2.4.1.3.4&lang=us&rev=10.6&ostype=Windows%207%20-%2064-Bit%20Edition

Good Luck!

It's no good I tried installing that update as soon as it appeared and it wouldn't install properly. It extracts to the specified path but near the end of installation says it's installed but when I look there are no files installed in the program files. I resorted to using ATi Mobility MODDER and whilst this worked it still didn't address the issue and so resorted to rollback to previous drivers.

I don't think it has anything to do with whether you have an intel or AMD as it seems to affect both.

It may well be the external harddrives but why should I disconnect them when I need them for my data storage? Disconnecting it is not a long term solution for me.

I recently built a new system as follows: Mainboard : MSI MSI X58 Pro-E (MS-7522) Chipset : Intel X58 Processor : Intel Core i7 930 @ 2800 MHz Physical Memory : 12288 MB (6 x 2048 DDR3-SDRAM ) Video Card : ATI Radeon HD 5700 Series Hard Disk : Hitachi (2000 GB) Hard Disk : ST3500418AS (500 GB) External Hard Disk : WD (2000 GB) DVD-Rom Drive : HL-DT-ST DVDRAM GSA-H42L ATA Device DVD-Rom Drive : TOSHIBA ODD-DVD SD-R5272 ATA Device Monitor Type : LG Electronics L226WTQ - 23 inches Network Card : RTL8168/8111 PCIe Gigabit Ethernet Adapter Operating System : Windows 7 Professional Professional 6.01.7600 (x64) DirectX : Version 11.00 I had frequent BSOD events and the computer simply would lockup when the screensaver was about to start. I decided to try updating all of the drivers as Bobby121393 and others had suggested here, but found that the Western Digital 2TB external USB drives claimed to soley use existing non-WD drivers. They didn't have new drivers, but they did have new firmware. Updating the firmware on the Western Digital drives stopped my BSOD issue completely. ATI had new Catalyst Control Center software for the x64 system. Updating that solved the freezing issue that occured when the screen saver was being started. Updating the Western Digital firmware and the graphic card drivers seemed to fix everything.
