Windows 7: Windows 7 randomly freezes for 30 seconds at a time

Windows 7 randomly freezes for 30 seconds at a time

To be more specific, it seems to just stutter. When I watch a video it will play a very slow, stuttery version of the dialogue that just happened. Same with music playing. But the mouse and screen are frozen.
When I start up my computer it doesn't happen yet but after a while (especially, it seems, with higher RAM use) it starts to happen more frequently and with shorter intervals.

Additional info:
I reinstalled Win7HPx64 about a month ago
I ran a disk check (I wasn't there to see the outcome but it didn't fix it_
I ran a memtest for two passes on both sticks of RAM
Running Process Explorer to investigate the problem but it still won't tell me specifically what makes the PC freeze.
I'm about to Decrap my PC. That probably won't fix anything but it's still necessary with all this VAIO bloatware.

What's my next step?

I just had another freeze and checked Process Explorer again.
It seems that the biggest factor is a spike in CPU0, with about 25% "Interrupts"
I hope that helps narrow it down.

You need to fill in your system specs completely.

Video card specs is most important here.

Get your latest drivers here:

AMD Driver Autodetect

Make sure all windows updates are applied, and you have all the latest drivers for your motherboard and chipset. I would also go further and make sure your bios is up to date.

Also go to sony's site to make sure drivers are up to date: (you will need your model number-if you could tell me what that is as well that would help)

Thanks for the help.

I've updated the AMD driver but couldn't find any updates for the motherboard, chipset or BIOS (that weren't already installed).
As you can see here, most of the drivers for my laptop are quite old anyway. Does that raise any suspicion? Intel does back that up, however, as there are only 2 downloadables for the i3 on W7x64 and neither of them are updates.

(For posterity, this site does a good job of finding all applicable updates on VAIO laptops.)

The model number is VPCEB2S1E/BQ in case you still wanted to check, but you can only do that via the European Sony website.

Any idea what I should do next?

Have you run any diagnostics on the hard drive ?

I did run the W7 Disk Check but I wasn't there when it was supposed to show the results as it took a while and I came back when my laptop had already booted up. Is there a chance I missed anything?

Is there any value in running Memtest again, for more passes per RAM stick? I have this nagging suspicion that the problem is related to RAM.

No harm in doing so. Memtest properly should run for 2 hours imho or overnight to make sure nothing is wrong.
