Another Windows 7 Freezing Thread

Sorry to beat this horse once again, but...

I have scoured the internet, I have reinstalled the operating system, I have uninstalled various software and still I have not found a solution as to why Windows 7 freezes randomly. I have some ideas as to what might be causing it, but I would need to test those ideas on three or four new computers with various hardware installed. I have five PCs and a laptop in my house, and with the exception of one I have Windows 7 installed on all of them. Unfortunately four of my computers are 7-9 years old and my theories as to what is causing the freezes wouldn't work on them. The freeze does not occur on any of my older machines.


Older PC specs:

• CPU - AMD Athlon 64 1.8GHz single core (on two machines) Windows 7 Home and Ultimate installed
• Motherboards - Gigabyte and Asus - VIA chips
• Video Cards - nVidia 6800 and 7800GT - both AGP
• Memory - both have 2GBs of RAM PC400 from Kingston

• CPU - AMD Athlon XP 1.8GHz single core - Windows Vista Home installed
• Motherboard - Asus - VIA chips
• Video Card - ATI Rage - AGP
• Memory - 1.5GBs of RAM PC400 from Kingston

• CPU- AMD Athlon 64 X2 2.2GHz dual core - Windows 7 Professional installed
• Motherboard - ASRock - AMD chips
• Video Card - nVidia 7900GT - PCIe
• Memory - 4GBs of RAM PC400 from Kingston

Newer PC specs:

• CPU - Intel Q9300 2.5GHz quad core - Windows 7 Ultimate and Windows XP installed on same HD but separate partitions.
• Motherboard - MSI - nVidia chips
• Video Card - nVidia 8800GT - PCIe
• Memory - 8GBs of RAM PC800 from Kingston

None of the older machines freeze when Windows 7 is installed. The only machine that freezes is the one with the Intel CPU. The CPU is not the cause though, because if you google you will see that many users are having the problem with AMD machines as well. All the older machines listed above have Adobe Flash and Klite codecs installed. One of my theories was that Adobe Flash or some codec was causing the problem. With the codecs installed the freezing occurs more frequently, but when I perform a fresh install of the OS without any codecs the freeze still occurs, just not as frequent. I am beginning to think that the problem only manifests when a particular combination of hardware and Windows 7 are installed. My reasoning is that not everyone is having the problem, even though they have the same software installed. I haven't seen the problem on laptops yet, which is very interesting. There are seven different laptops (all with Windows 7 installed) in my wife's family, and none of their users have reported this problem. I'm thinking the freezing has to do with a certain type of CPU (more than two cores) or RAM (DDR2 and above) in combination with the operating system.


I love Windows 7, and I think it is the best operating system Microsoft has produced to date, but the freezing is driving me nuts. If it weren't for OneNote, Photoshop and some games that I am very fond of, I would switch to Linux Ubuntu in a heartbeat.

Check the temperature of the processor and the graphics card. Check the heat sink,if it's so dusty clean your PC with a dry air dust cleaner.

Hello NuclearDreams and welcome to Seven Forums.

Have you considered stress testing the computer to see if it's a hardware issue?

HeavyLoad - Free Stress Test Tool for Your PC

You can also use individual tests on individual components:
Prime95 for CPUs
Memtest86+ for Memory
ATItool or Rivatuner or FurMark for Graphics Card

If it was me I'd be working with the voltage settings in bios. Slight adjustments to the CPU, Memory or north and south bridge voltages can have a drastic effect on stability. The default voltage settings aren't always correct, this is why they are made to be adjustable in the first place.

People sometimes act like the machine will blow up if they adjust the voltage settings in bios but I can assure you that isn't the case. I've successfully overclocked many different CPU's and I've yet to ruin one of them. Contrary to what they seem to believe over in the BSOD section, updating drivers isn't the only way to fix stability problems which is why it doesn't work most of the time.

I would make adjustments to one voltage setting at a time starting with the CPU, then to memory then to NB and SB voltages, then see how each one affects stability. Using a slow but sure process of elimination should eventually yield some positive results.

Are you following Best Practices for Win7 install as detailed in Clean Reinstall - Factory OEM Windows 7,
only using drivers which Win7 delivers in installer and via optional Updates then supplying only missing drivers?

Try wiping the HD first: Diskpart Clean Command

Then if problems persist work through these Troubleshooting Steps for Windows 7 establishing a Clean Boot, scanning logs for repeat errors, utilizing System Resources to find solutions.

If I have to jump through that many hoops just to get Windows 7 to function the way it should, then maybe I should switch operating systems. I am not the only one having this problem though. If you type "Windows 7 Freezing" in Seven Forums' search engine you will get several pages of complaints. You will also get the same results in Google. Speaking for myself, this problem does not occur in Windows XP/Vista or Linux, only in Windows 7.

About the test and adjustment I explained in my earlier post, it didn't work. For several hours after I made the adjustment the PC didn't freeze. But as I moved the mouse, after an hour of being idle, the PC froze. Again, I have Windows XP and Linux Ubuntu installed parallel to Windows 7, all on separate partitions. Those operating systems do not freeze.

You're welcome.

How does establishing a Clean Boot affect it?

Rebooting causes the system to function as normal, until the next freeze. The next freeze could happen hours or even days after the reboot. Today I've had to reboot the system four times. Reading other user's complaints, I see that some have to reboot their systems even more often than I do.
