Computer keeps typing LOTS of zero's!

Hi there everyone, I need immediate help!
For a while now I have been having this bug where my computer just keeps constantly typing zero's like this "000000000000000000000000000000000000000" without me doing anything.

A few points I should mention

1.IT IS NOT THE KEYBOARD!!!!!!!!
-I have unplugged the keyboard and the problem still persists

2.The issue normally starts after watching a movie, a long video or after playing a game.

3.My antivirus software couldn't find anything.

4.It is always fixed with a good ol' restart but it is REALLY annoying to do this.

Please if you know what the problem is or if you have any ideas on how to fix it PLEASE post a reply! Thanks in advance for everybody's help.

Sounds almost like the memory modules are storing data while they're being stressed buffering the movie, video, etc. So I think I'd remove the module(s) and try reseating. If you have two modules or more, install just one and run the computer for a while to see if everything works. Then try the next module. Sometimes you can determine if one is bad. If all modules seem to work individually, reinstall all of them and run a stress test like Memtest86+.

Memtest86+ - Advanced Memory Diagnostic Tool

You can also check CPU, mobo etc with another tool called Prime95.

Torture test your CPU with Prime95

Thanks for the advice but how exactly do I use these tress test programs? Do i download and run or is there an operation?

~edit I have not tried the remove memory yet

Windows 7 also has a built in memory diagnostic tool. Let's start with that.

If it detects any problems, or if you still want to run Memtest86+, you'd have to download an ISO file and save it to a convenient location like your desktop. (This is just a special kind of file that contains the Memtest86+ info as well as special instructions for your computer.) You'd need either a blank USB flash drive, or a CD, or a DVD to create the actual media to run the test. This tutorial explains how:
