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

Reinstalled for the third time, scanned both harddrives with spybot, nod32, avg and malwarebytes. No issues. Ran chkdsk on both, no issues. Got to play my Left 4 Dead 2 demo without any problems, going strong now.

Before I performed my latest reinstall, I ran Task Manager>Performance>Resource Monitor>Disk>Processes with Disk.

And I ended up getting the problem txtomcat had; svchost.exe's starting. Only 5-10 to begin with but after 5 minutes or so, there were more than 100.

Installing Aion from scratch at the moment. Just installed Direct X 9.0c from the disc. Gonna suck having to patch it again but oh well.

Wondering how long 7 will go without problems this time.

Having the same problems as all of you as well. Computer will randomly freeze up anywhere between 5 minutes to 1 hour or so. Havent found anything that I can possibly call as a clue to why this is happening. Just upgraded to windows 7 last week, and everything worked just perfectly for a few days. I then loaded up Heroes of Newerth and played for approx. 30 minutes before I got my first freeze-up. Now the freezing has not stopped. All CPU, GPU, ACPI temps are normal. I feel as though the only hardware that could be causing this problem is my Power Supply, But I am not even sure if that is it. My northbridge fan is not spinning, but that is probably not the case for this problem to be occuring.

Here are my specs

Intel quad-Core Q9650

Asus P5N-D Motherboard

8 Gigs Ram DDR2

2 GTS 250 Nvidia Vid Cards

I know we are all experiencing the same problems.. so any help would be amazing.

also just to add, I have frozen in safe-mode.. multiple times. I do not feel as though it is performance related because it will freeze even if I am idle on the desktop screen. Nothing seems to trigger this problem.

I am using Avira Anti-Virus, idk what else to state... Ill edit if i think of something.

Used repair function from install disc and it's running much more smoothly with a few hickups here and there but not as bad as before. I will keep you posted on whether it keeps working or not. Give it a try.
