Windows 7: Completely Random Hangups / Freezes

For a week now, my computer has been locking up, freezing, hanging, whatever you want to call it, at completely random times. Sometimes I am using it, sometimes it's been sitting idle for an hour or more.

I reinstalled Windows on a fresh hard drive and recovered my pictures, documents, and music from a backup and still have the same problem.

I pulled out all the RAM and reseated it, and ran Memtest86+, which it passed with flying colors.

I was cooling the CPU with a Corsair H50, and the intercooler was full of dust. I removed it and replaced it with a regular heatsink (yes, I applied thermal compound). The CPU is now running around 40 C.

Any help that can be provided is greatly appreciated.

How old the system is? Is it still in warranty? If so, contract the vendors.

Otherwise, break it all in parts, clean all the dust, moisture, and set the system up again.

Earlier I used to use an ASUS based system, and it was very frequent for me a time.

Hello mmbruce10 and welcome to the forums

Have you overclocked any of your hardware at all? I experienced lockups like this when my CPU and GPU OCs were unstable. If so, what voltages are you running at?

With an H50, my guess is that it's a custom build. I don't know any companies that use H50s as stock components. If so, it won't have a warranty and a vendor won't help unless we can narrow it down to an individual part which we can then RMA. I've got an ASUS board as well and it works fine

You might try a newer GPU driver.
Try these steps to install only the graphics driver.

1.Download the preferred driver and save it to the desktop.
2.Double click the installer and you will see a screen where it will be extracted to, change that to your desktop.
3.Open Device Manager through Control Panel.
4.Expand Display adapters and right click the name for yours and choose Update Driver\Browse my Computer. Select the driver folder you just saved on the desktop. Click Next.
5. Your system should say "Windows has successfully updated your driver software".

If you get a window saying you already have the most current driver, go back to step 4 and choose Uninstall Driver software instead. Then restart from step 3.
