Hi Jacob,

It depends on what level of freezing you are experiencing. A random freeze once a month is definitely a different problem than 10 to 20 freezes a day.

You can follow the below steps:

Check Event Log

The first thing to do is to try and check the Event Log and see if there are any events in the System or Application log that could help you identify the problem. Look for yellow exclamation and red x icons right around the time the computer froze.

Now a lot of times you may not see anything useful in the Event Viewer because if the computer freezes, then the events may never get written into the log. 
If you do see something useful, but you’re not sure what it means, then post the contents of the log here and I’ll try to help you out.

Disable USB, Network and Other Devices

If you have an ASUS or Gigabyte motherboard, there seems to be a lot of issues related to Windows 7 64-bit. Users have reported disabling certain hardware components has fixed the problem. Obviously, disabling your USB ports is not ideal, but you can at least try it out and see if that’s the issue. Try to disable everything you can including the network card, card readers, other ports, etc.
You can also go into Device Manager from the Control Panel and disable hardware from there too if you can’t figure out how to do it in the BIOS.

Update Drivers & BIOS & Windows Updates

Though this doesn’t help in most cases, it does in some. Go ahead and update all the drivers for all hardware on your computer including the hard disk, network card, sound card, graphics card, and anything else. It’s best to go to the website of your computer manufacturer and download all the latest drivers from there.
It’s also a good idea to go ahead and update the BIOS to the latest version, especially if you’re running Windows 7 64-bit. Sometimes this helps clear out power issues caused by ACPI, etc.

Uninstall Third-Party Software

From the software side of things, if your computer is freezing, it could be due to a third-party program like an anti-virus program or anti-spyware app. I’ve seen lots of freezing with some users running AVG or ZoneAlarm on their systems, but it could be any software.
If your system was running fine until recently, then go back and see which programs you recently installed and uninstall them. Some programs just don’t run well with Windows 7 64-bit and end up causing a lot of grief. If you have a high end system with top-notch specs, then it could very well be related to a crappy piece of software that was not written to for 64-bit and is therefore running in a 32-bit mode.

Repair Windows 7

Just to rule out any issue with Windows 7 system files, go ahead and boot off the DVD and run the Startup Repair. Once you load the tool, you can perform a startup repair, try a system restore, or go to the command prompt. At the command prompt, you can try running a couple of commands:

chkdsk drive: /r
sfc /scannow

For chkdsk, just replace the word “drive” with the drive letter you want to scan, i.e. C:, D:, etc. The sfc command is the System File Checker, which will go through and fix any issues with corrupted or missing system files. So basically, you need to run the startup repair, try a system restore and run these two commands at the command prompt.

Adjust Power Settings

Windows 7 has some advanced power settings that can also cause more problems than provide benefit! Go to Control Panel, Power Options and click on Change Plan Settings next to the power plan you have selected.

Now click on Change advanced power settings.

Now scroll down and disable the USB selective suspend setting and the PCI Express – Link State Power Management setting.

Make sure they both say “Off”. Go ahead and try to reboot your computer and see if the issue has been resolved.


I hope this helps.

Lokesh.
