Windows 7 - Full screen videos crashing to black screen and buzzing

My computer has a problem with crashing while playing a video in full screen. When it crashes the screen turns black while the speakers give out a buzzing noise. Everything is unresposive the only solution is to turn it off with the power button. It happens in any full screen video online or offline and even visualizations from windows media player and iTunes, but only in full screen. I don't think it's overheating either because sometimes it takes 30 mins to crash and other times it will crash immediately when put in full screen. *I've tried setting it back to factory settings thus reinstalling windows. *All the directx features are working with no reported problem there.*
I don't think it's a memory issue in the computer, as my specs are:
Windows 7 64-bit
Processor: intel core i5 3.20 GHz
Ram: 8 GB
Graphics card: NVIDIA GeForce GT 220
Graphics card memory: 0.5 GB
Any other ideas?

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.



To ensure minidumps are enabled:

Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
OK your way out.
Reboot if changes have been made.

I am also experiencing the same problem as these two posts "Full screen videos crashing to black screen." Is there a solution?

Thanks.

thanks for the quick reply zigzag3141, things got busy and I didn't have time to try to fix it like i hoped but it's happening more often now.. here's the minidump files attached with this post. It doesnt have to be in full screen to crash anymore. it just crashes randomly. will post pictures of what it's done in the past. I recently ran dell diagnostics and everything passed. then once when it crashed it said it couldnt find the 3rd and 4th sata drives and when I ran diagnostics then it said that it could not find the drive and i needed to reinstall it, however after deleting the data that windows was trying to resume from. it regonized the drive and booted fine. it still crashes quite often periodicly, sometimes it's black with buzzing if the sound was set loud enough and other times it shows weird colored blocks flashing around the screen. any ideas for a solution? thanks!

here's some of the pictures more to come

Qwerty5 did you ever sort this problem out??
