Random Split-second Freezing Problem

I have a Dell Inspiron 620 that I'm having a problem with. At seemingly random intervals it'll freeze for a moment then work fine until the next freeze.

Every diagnostic I've run from Dell's website says everythings fine and all my scans show the same. Does anyone know what this issue is a sypmtom of and, more importantly, how to fix it?

Can you be more specific?

When you say freezes, are keystrokes frozen? Video? Wireless/ethernet? Does it always happen during the use of one particular program? What are the specs of your 620? Processor, ram, gpu, etc.

The more information you can give us, the better we can try to help.

Well, when it happens everything on screen stops for the duration (mouse pointer doesn't move, things moving on screen stop, any typing doesn't register) and if there's sound going there'll be a buzz at the pitch of the last sound. It doesn't seem to be on any particular program, as I've seen it happen during start-up

As for specs:
Processor: Intel(R) Core(TM) i3-2120 3.30 GHz, 3300 Mhz, 2 cores, 4 logical processors
RAM: recently upgraded to 8GB in attempt to fix this problem
Graphics card: AMD RADEON HD 6450
Hard Drive: ST31000524AS ATA device, 1TB 7200 rpm
Internet connection: ASUS 802.11n Wireless LAN card

That's about all I can find

Random glitches like that are hard to pinpoint.

Here's a few thoughts:

Download and run malwarebytes. See if perhaps a virus has snuck in.
Are you using the original psu? Sometimes a failing psu will throw spikes that cause this type of glitch.
Is the 6450 original equipment from Dell? If not, did you COMPLETELY remove all prior drivers? Driver issues often cause momentary "locks" that affect all the parts you describe. You can try removing your video drivers, then using driversweeper and/or ccleaner to clean up any left over cruft. Then install the most current AMD drivers.
Also, make sure your bios is current - sometimes a bios update will cure annoying little issues like this.

I scan with malwarebytes every couple of weeks so I've got that covered.
Yeah I still have the original psu. I've noticed that the fan on it seems to be blowing out warmer air than the other fans so that may be the issue.
The 6450 came with the comp so I think that should be fine.
I'm not sure about the bios, so I should probably take a look at that.

I see if updating bios fixes the problem, if it doesn't I'll see about the psu. and if that doesn't work I'll check back.
