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 all,

Here’s my story so far, re-Win 7 64bit random freezing and re-boots.

System specs:

i5 2500K CPU LGA 1155 3.3GHz (no overclock-ever) CM Hyper 212 Plus cooler, arctic silver-5 TP

Gigabyte GA-P67A-UD3R Board (now GA-Z68XP-UD3R)

4x2Gb sticks of G-Skill DDR3 1600Mhz PC 12800 RL 9-9-9-24(CL9D-8GBRL)

Sapphire ATI HD 5770 Vapor-X OC-Ed 1GB GDDR5 PCIe

intel X25-M 320s 120Gb MLC G3 SSD Drive (system drive)

2x320Gb Seagate ST3320620AS in RAID O (firmware upgraded from AAK to AAM) (programs & games)

WD 1TB 64M Sata3 WD1002FAEX (storage & backups)

Pioneer SATA DVR-219L DVD Burner

Corsair HX-620w PSU (now Vantec ION2 620w PSU)

Microsoft Windows 7 Home Premium 64Bit

Fearing I had some faulty hardware as suggested in this thread, I have replaced the following;

Motherboard, from GA-P67A-UD3R (9mths old),(not B3 rev), to Brand new GA-Z68-XP-UD3R

PSU, from HX-620w (9mths old) to Brand new Vantec ION2 620w

All the rest of the hardware is less than 9mths old, and I refuse to fork out for MORE!

CPU passed 8hrs of prime95 torture testing

RAM passed 5 consecutive passes of MEMTest 86+ (64bit) after 3 consec passes of Windows RAM test

First off, I myself began experiencing these problems after I downloaded & installed “Windows Updates”. Prior to this, my daughter’s new PC was running fine!

I have updated the board’s BIOS from F4 to F6c, installed latest graphics drivers + all other drivers from manufacturer’s websites only. Re-installed (after low level formatting) OS to SSD drive 4 times (ACHI mode) BIOS set to “Fail Safe Defaults”. All other drives disconnected. Changed power settings to High (everything under “advanced settings” HDD, NIC etc, etc) no sleep state whatsoever.

Ran Malwarebytes, CCleaner 64bit, MSE.

Downloaded & installed Hotfixes;”Fix322397”,” Fix302249” = No joy!

No AV installed other than MSE.

Disabled all non-microsoft services in msconfig, (only others are intel services for SSD drive, as no other software is installed apart from MB drivers, no APPS)

The PC has gradually gotten worse, now won’t even install updates, (causes failure-freeze-then consequent reboot), will not stay “alive” long enough to perform a “Windows Repair” install. Freezes are totally random in nature, 30secs – 5 mins mostly, sometimes hours (provided you don’t do anything with the PC). Double reboots, freezes on loading OS etc. Easy to cause a freeze, just run either windows update, or “rate this computer” and BAM! Freeze & auto reboot. All while “Fail Safe defaults” set in BIOS F6c.

I’m so sick of seeing the “Windows was not shut down correctly” boot option screen! ARRRRG! It’s like the thing now has a mind of it’s own. I sat & watched it do it’s own thing for an hour, reboot……freeze…..reboot…..download updates…..freeze… reboot, then tell me that updates FAILED and that reason is, Quote: My BATTERY is getting LOW? Seriously!? It’s 240v mains power for christ’s sake! How much more power do you want???

Hardware problem my a$$. This is clearly software run amuk!! And since it is only Microsoft’s software that’s on the damn thing???......

First time I've ever had to use this forum! Apparently I cannot attach a system error report for your perusal?

I am as exasperated as you all and desperate to find the answer.

I'm no geek so I will need some of you who are to tell me if this is an issue or not? When I kick firefox (Firefox.exe *32) off and go into the task manager it shows:
1. Memory (private working set) about 135mb
2. Peak Working set (Memory) about 180mb
After accessing my mail and surfing etc in Task Manager I notice this difference:
1. Memory (private working set) +600mb
2. Peak Working set (Memory) +700mb
Is there a problem with memory leakage or the like or is this normal?

HP Pavilion Dv7 2014TX, Intel Core2 Duo, T9550, 2.66GHz, 4GB, W7 Ultimate 64Bit.

Dual 500GB disks.

Hi goneil99,

Not sure if you are actually experiencing "memory leak", but there is an article on Tom's Hardware regarding it here;http://www.tomshardware.com/news/Windows-Microsoft-BSoD-Hotfix-OS,9637.html

Be very careful though, as if you're not getting the BSOD with error:

"STOP: 0x0000000A"

It may not be for you.

The "Hotfix" can be found here;http://support.microsoft.com/kb/979444/

Note: Read the article in FULL before using the Hotfix!

Quote: Hotfix information A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.

Hope this helps
