Windows 7 Minimizing Full-Screen Games and Regular Windows

[Triplenox]

Hey, I have a problem, firstly here are my system specs:

AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ 2.60 GHz
6.00 GB DDR3 RAM
Windows 7 64-Bit Home Premium
ATI Radeon HD 4300/5000 Series

My problem is that when I am playing games such as Minecraft or full screen games like Half-Life 2 and Counter-Strike: Source, windows decides to Tab Out... When I (it just did this then) press a key it makes the noise that windows normally makes when you can't use the keyboard (I have no idea what to call the noise o.o) Windows also (it just did it again) basically makes the window look like another window is on top of it here, is basically what it looks like (on the right, I decided to put skype and chrome next to each other and click on skype which makes the top of chrome look (it just decided to do this again) like it's basically not in use, I really do not know how to describe this here is an image w/ the comparison http://puu.sh/1RDgf As you can see on the right (Chrome's top bar is abit lighter than Skypes)

This is really annoying, and I really cannot explain the reason fully, I have re installed windows once, and this does not do anything, so I am not going to try this again! I've tried in my best ability to explain this, but let me say one last thing, It basically seems like another window is popping up, but cannot be seen and this is making my games and normal windows tab out... I can tell because chrome or the game I am playing will either make the top bar look lighter or just minimize and then when I press a key it will make a noise, unless I press the mouse button which gives me control of the pc again.

I would hope someone can understand all of this, because I have looked all over and I cannot find ANY solve for this, thanks for your help:

I think I have fixed it, I just did the following:
I saw that a program called "wermgr.exe" was opening and closing (Windows Problem Reporting) I pressed the start button and searched for "Choose how to report problem" and then I clicked it and then I clicked "Never check for solutions" which then fixed the problem which has not happened for the past 15-20 Minutes!
