I have have this horror issue with my PC. I have even changed the hardware configuration and the problem still persists. My PC fails to display the desktop correctly after using highly RAM intensive applications, especially Chrome, but even after getting the chance to close it, or waiting for it to crash by itself, the PC is still not able to display correctly the GUI, even on other browser/applications as shown in the screenshots.
1st Hardware Config:
Intel Core2Quad Q9450
MSI P43 motherboard
Ati Radeon x550 video card
Software used, that seemed important for me to mention:
Comodo Firewall 5.12
Aero is disabled, because I've considered that it's one of the causes.
So, I've considered that it's a RAM issue or a videocard issue, and I've upgraded to:
Intel Core i7 3770k
Asus P8Z77V-LX motherboard
Intel GPU integrated in the 3770k CPU
The problem just happened 2 times on this rig also, and the RAM was not even coming close to it's maximum capacity of 31.7GB. It was at ~20GB's.
Also, this is another videocard(Intel's integrated GPU), so we can exclude the videocard from the suspects.
1) some desktop manager bugs, or other similar issue
2) video memory allocation - I'm still suspecting that it can be caused by the amount of RAM dedicated to the videocard, currently, I think that it is at 256MB.
3) some poorly designed components of Chrome/Screenshot Captor - still very questionable since there are enough resources on this system, so there should be no fight over resources. And when the system is barely used there are no issues.
4) Adobe Shockwave Flash - maybe this one????
I have attached a set of 20 screenshots here, these were taken on the 1st configuration of my PC, using Q9450:
Notice how it distorts the image by duplicating it and showing it in a smaller space, or how does it displays those black rectangles. In those moments, the PC is fully functional(the apps are running the background), without being slowish or something, but you can hardly control it like that. For example, I've tried to remove the mouse from the USB, and then I've insterted it back, the image was not displayed correctly, but the mouse was recognised instantly and the pointer was controlable.
Same thing still happens on the new configuration. Please advise me.
LE: OS is Windows 7 x64 SP1 Professional and it's Geniune. There is no cracked software on this PC. No games. I've tried to maintain it as clean as possible.

First, please be ensured that you have installed the latest drivers and all the updates.
In addition, try to create a new profile to see how it works.
Hope this helps.

Thank you for your reply, Vincent!
Since it happened on 2 distinct platforms, which needed different drivers for chipset/audio/video/etc, for start I am a bit more interested to discover how does Windows 7 "render" the GUI's for each window. Maybe there is some issue around here.
I think that I exclude Screenshot Captor and Chrome, since it behaves the same, even after turning these 2 off.
Reinstalling and readding settings for each program, and so on takes a lot of time, and I am looking at it as a final measure.
I want first to find out how does windows 7 work when it comes to handling GUI's. If you could give me some info regarding this subject, it would be really helpful.
For example, do I need Desktop Window manager? Can I turn it off?
