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'm also having this problem with my Windows 7 64 Ultimate It's been driving me crazy to no end, haven't found a fix in this thread yet, but haven't read through it all as of yet because it's so long :) Hopefully I can find one in here somewhere.

Case: Antec Twelve Hundred Ultimate

Mobo: Asus - P6T Deluxe V2 X58 w/Triple DD3 2000

Processor: Intel Core i7 920 – Overclocked to 3.8Ghz

CPU Cooling: Thermalright Ultra-120 eXtreme 1366 RT CPU Cooler w/ 120mm Fan

Memory: Corsair 12 GB XMS3-1600 PC3-12800 Core i7 Triple Channel DDR3 Kit (6x2GB)

Hard Drive: 2x Western Digital VelociRaptor 150GB 10,000 RPM SATA II w/16MB Cache - Setup for RAID 0

Optical Drive: LG Super Multi Security DVD Writer 22x, SATA, Black

Floppy: Mitsumi 1.44MB

Video Card: eVGA e-GeForce GTX 295 1792MB PCI-E

Sound Card: Creative Labs Sound Blaster Audigy SE 7.1

Power Supply: ANTEC TruePower Quattro 1000W

Operating System: Windows 7 64 Ultimate

Display: 32” Samsung Widescreen TV

I have the processor OC'd to 3.8ghz, which I have recently reduced to 3.7. I had reset it to stock speeds as I thought that may be what was causing my lockups, but it wasn't. Tried a lot of different things, including reformatting etc.

The computer freezes up randomly. Sometimes moments after a boot after loading windows. Other times I can have it running all weekend with zero problems. Or it will freeze up while playing a game. I almost always have to hit the reset button, or hold the power button. Sometimes it will reboot on it's own, though.

The hotfix further above did not work for me.

I've been having the same freezing problem since day 1 MS released Win 7 ultimate x64 in stores and I can't figure out what's wrong at all. I started on the following system: Intel q9550 Gigabyte EP45-UD3P BFG Tech 7600GT OC Seagate 250GB HDD Crucial Ballistix Tracer PC2 6400 2GB kit Samsung DVD multi burner Had freezing problems that I couldn't track down, tried everything, switched to 32 bit, nothing... so I swapped out the RAM for G Skill DDR2 1100 4GB kit, HDD for a WD 500GB, and the video card for a Zotac 9800GT... no joy... Now I just rebuilt the system again after just using XP for about 6 months and I'm having the same problem on what is now a completely different system: Intel i5-760 Gigabyte P55A-UD4P A-Data DDR3 1600 4GB kit Gigabyte 9800GT Asus DVD multi burner WD 500GB HDD Now that I think about it, the only common denominator between each variation of this machine is my wireless PCI card... Could that be the problem? It's an Edimax card that uses an RA Link chipset. The thing is that it has always worked fine with XP (which I'm using now on a dual-boot), so could there be a conflict with Win7 that isn't present in XP?

Five days since I uninstalled Relevant Knowledge and I haven't had a freez-up yet. This is the longest I've ever gone since the problem first appeared.

Hallelujah!
